Dismantling the foundation: methods, main stages and recommendations

You can dismantle the foundation of a permanent structure yourself, but it is not always rational. Sometimes, it is better to contact a construction company. It will turn out even cheaper. For a small area of ​​work, it is enough to consult with specialists. They will be able to guide and explain competent technology for dismantling manipulations.

Estimated cost of work to dismantle the house to the foundation level:

Loading waste into a container 27m3 = 9t.r. (When setting up to 10m from dismantling)

• Columnar or pile - analysis of this type of foundation is carried out using heavy hydraulic equipment. The piles/pillars are pre-stretched and freed from the soil.
• Belt - small in area, which can be destroyed using a hammer, sledgehammer, hammer drill, or diamond disc.
• The most difficult block type - its removal is carried out only using special equipment. If there are no residential buildings nearby, then you can use explosives.

When special equipment is used, the process of destroying the old foundation proceeds quickly and smoothly. The specialists of the First Dacha Company take into account all the nuances of the process and strictly follow safety precautions to avoid negative consequences. The use of modern technologies can reduce work time and reduce costs.

Stages

Methods for dismantling the foundation

Method No. 1 Manual dismantling.

For this purpose, a crowbar and the worker's muscles are used. This method of disassembly is only suitable for a brick foundation.

Method No. 2 Dismantling with a jackhammer.

If the entrance to the object is closed or the foundation is small, then it is possible to use a jackhammer. This work requires a lot of physical effort, so it costs more than dismantling using machinery. It is worth noting that we recycle disassembled foundations and transport them in containers from 8 to 20 cubic meters.

Method No. 3 Using an excavator.

If the foundation is made of concrete blocks, then it can be dismantled using an excavator bucket. Concrete blocks are heavy and are placed in the ground in several rows. Using an excavator, the blocks are pulled out and loaded onto a dump truck. Sometimes this method is used to dismantle a brick or strip base. This method requires a trawl to deliver the excavator to the site, which significantly increases the cost of dismantling work. Therefore, it is advisable to use an excavator to carry out a large volume of work or when complex work is being carried out to demolish a house and its foundation.

Method No. 4 Using a hydraulic hammer.

This tool is an attachment to an excavator boom that works like a jackhammer. It is used for crushing concrete or brick when dismantling strip or brick foundations. The loader loads the waste onto a dump truck with its further removal outside the site.

Method No. 5 Non-explosive method of destroying the base.

Holes are drilled in the concrete foundation into which a special mixture is placed. Under its influence, the base turns into crumbs within two to three days. The rest is disassembled manually using a crowbar or sledgehammer. The time frame for dismantling the foundation of a private house is one to two days. It is believed that it is better to do such work in the summer due to the dryness of the soil at this time of year. In autumn or spring, the soil is very waterlogged, which complicates the work of equipment and destroys the appearance of the site.

Dismantling and disassembly in stages

Our specialists visit the site to draw up a robot schedule and familiarize themselves with the features of the upcoming disassembly process. In captivity, means and methods are prescribed that will be optimal in a particular situation. We clearly apply the necessary effort and resources when disposing of waste and minimize costs. The team begins dismantling using the chosen method and removes all resulting construction waste. In any case, you can find out about specific installation methods specifically for your facility only after our specialist has visited the site and preliminary inspected the area with the foundation.

The cost of base removal depends on the following factors:

• What equipment will be used in the process and what tools are needed;
• What is the foundation made of?
• Depth and width of the base;
• Base type;
• Is it possible at the site to provide power supplies for tools?

In addition, the remoteness of the object, where it is located, and whether there are residential buildings nearby play a role. The first dacha company offers its services for dismantling foundations of any type using manual labor or special equipment. Contact us now and find out all the details of the work. Our employee will visit the site completely free of charge to carry out calculations and determine the dismantling method. We will carry out the necessary work quickly and at a high professional level and at a competitive price.

Turnaround time

The specific duration of the manipulations associated with the dismantling of the old base depends on its type and specifics. The complex process requires the involvement of special equipment and a team of professionals. Dismantling the foundation usually takes no more than 1-2 days. This is relevant when there are no problems with the access of equipment to the place of operations.

It is advisable to carry out work on dry, fairly dense soil. Otherwise, the wheels of special equipment will damage the appearance of the site. Waterlogged soil also contributes to an increase in work time.

Dismantling and demolition of reinforced concrete foundations of houses, dismantling reinforced concrete

In a metropolis like Moscow, today there is an active construction of facilities for a wide variety of purposes - residential, commercial, industrial.

Often, construction is carried out on land plots that previously contained buildings and structures. In many cases, such areas contain remnants of an old foundation that must be removed before construction begins.

Dismantling the foundation is one of the important stages of work in cases where buildings are demolished.

Foundations are the strongest part of a building's structure. In addition, a key feature is their underground placement. This makes dismantling much more difficult.

Work with the foundation has to be carried out using various types of special machinery and equipment. Also, qualified personnel may be required to dismantle the foundation. Therefore, it is recommended to trust only professionals to dismantle the old foundation. A specialized organization will be able to solve the fundamental “tasks” as quickly as possible and dismantle it efficiently. If you need to carry out foundation demolition in Moscow, our company will be able to offer its qualified services.

How to break the foundation

Secrets of dismantling: how to remove the old foundation
Often, when purchasing a plot of land or inheriting it, you end up with a dilapidated house that can no longer be used.

And if breaking the upper part of the structure does not present any special difficulties, then in order to remove the old foundation of the structure, you will have to suffer quite a bit.

Not everyone knows how to remove the old foundation. Today we will talk about this.

The abundance of different types of foundations for a house or outbuilding does not imply the use of one universal method of dismantling. Let's look at the main types of foundations and how to destroy them using mechanical devices or on your own.

The simplest option for both installation and dismantling is a brick columnar foundation, which consists of several separate supports partially buried in the soil and protruding above it. It is made by laying it on a cement-sand mortar. Sometimes reinforcement is placed in the seam for strengthening.

Columnar brick foundation: diagram and implementation

In order to be able to break such a foundation, it is enough to have a construction chisel and a hammer or sledgehammer, since removing the foundation of such a structure is not difficult.

The main task is to break the masonry joint. To do this, just place the chisel on the seam and hit the striking part several times.

This way you can gradually break each old column.

Difficulties may arise when working with the underground part.

To facilitate the process, you will need a simple bayonet shovel, which is used to dig around the perimeter of each foundation to the very foundation. After this, you can continue working.

After removing all the supports, all that remains is to level the site as it was and you can use it at your own discretion.

Dismantling the foundation - preparatory work

Before starting to dismantle the foundations, it is necessary to carry out preparatory work. First of all, specialists perform a thorough examination of the object to be dismantled.

It is necessary to study to what depth the foundation to be demolished is laid, what materials it is made of, and what condition it is in. For this purpose, technical and design documentation for the foundation (if available) is provided.

In many cases, there is no documentation for the dismantled object. Therefore, a physical examination of the foundation, which should be carried out by qualified engineers, is of particular importance.

After completion of the survey work, a project for dismantling work is developed. It is determined what machinery and equipment will be used to dismantle the foundation, the required number of workers, and a demolition plan is drawn up. Safety measures are being developed during dismantling. At this stage, the estimated cost of the work is determined, as well as the time frame within which the foundation will be dismantled.

Dismantling the foundation

To carry out professional dismantling, you have to use various types of special equipment and equipment during demolition. The composition of the technical means used depends on the type of base being dismantled and its characteristics.

In most cases, it is necessary to dismantle foundations of strip and monolithic types .

Dismantling is carried out using special equipment to carry out excavation work to open the foundation. So, to demolish the foundation, you may need an excavator, loader, or bulldozer. It is necessary to use various types of hydraulic equipment. Dismantling can also be done using a hydraulic hammer, which breaks concrete structures (see section Dismantling and demolition of concrete structures).

Another common type of equipment for dismantling foundations is hydraulic shears.

Dismantling a strip foundation is relatively simple and faster compared to a monolithic foundation. With a small thickness of the structure, dismantling work is carried out in a short time. When dismantling, hand tools can be used - powerful hammer drills, jackhammers, etc. Plasma cutting equipment will be required to dismantle reinforced concrete structures.

Heavy hydraulic equipment is used in cases where it is necessary to dismantle the powerful foundation left behind a large multi-story building.

Dismantling a monolithic foundation can present the most significant disassembly challenge. In some cases, blasting may be required. However, it is important that there are no buildings, structures or other objects nearby that could be damaged by flying fragments.

Prices for dismantling the foundation are determined based on the volume and level of complexity, as well as the labor intensity of the work.

Destruction and demolition of strip foundation

The foundation of a building has always been one of the structures that are built to last for decades of use. As a result, in the vastness of modern Russia today you can find foundations of completely different types - from hand-made pile foundations to strip foundations up to 1.5 - 2 meters deep. As you understand, the elimination of such “self-constructions” takes a lot of effort and time and is often impossible without the use of specialized units.

Do you want to completely free the site from old dilapidated buildings and not come across shards of concrete when landscaping the site? We advise you to contact professionals who have extensive experience in dismantling various types of objects. It is they who will be able to completely and with a minimum of excavations saw and pull out the remains of the foundation blocks, including all more or less large pieces, sharp fragments and rotten reinforcement.

Such specialists have been working successfully in our company for a long time, carrying out dismantling operations throughout the Moscow region. Specialized equipment delivered to the company from abroad is highly reliable and has excellent power characteristics. Therefore, we work practically without interruptions and failures, completing clients’ tasks in the shortest possible time. During demolition, both pneumatic equipment and mechanical tools are used - all systems that can be useful and effective for completing a specific order are used.

Demolition of an established and settled foundation is a rather labor-intensive process, both in terms of preparation and in terms of performing the work. They use jackhammers, concrete breakers complete with a compressor, grinders and much more. The exact composition of the master’s tools is determined after inspecting the scene and the concrete used in the pouring. Elimination of a concrete foundation can be complicated by the presence of blanks for the basement, great depth and connected communications, and these points undoubtedly need to be taken into account during the demolition process.

Dismantling of concrete structures may be necessary in various circumstances, and not only for obsolete structures. Dismantling actions are used, among other things, when pouring is unsuccessful, deep cracks appear on a relatively new foundation, etc. We are ready to help you in every such case - at a low price, promptly and using modern technology.

When is it relevant?

The reasons for dismantling the foundation may be different.

• Owners of summer cottages often decide to build a full-fledged cottage with all amenities on the site of a demolished garden house. The existing foundation, which is not designed to withstand heavy loads, must be removed to create a new and strong foundation.
• When reconstructing a building, adding a second floor and expanding the area, the old foundation must be removed in order to build a stronger foundation designed to withstand increased loads.
• The foundations of unclaimed or unfinished buildings are removed so that the freed space can be used for other purposes.

specializes in dismantling work of any level of complexity. Dismantling a reinforced concrete foundation is a common and familiar task for the company’s employees.

We are able to free the site from any type of foundation:

• reinforced concrete,
• tape,
• pile,
• block
• monolithic.

For responsible and thoughtful organization of work, we draw up a detailed event plan. We make sure to evaluate the location of the property and its proximity to neighboring buildings. To ensure convenient access for equipment, we are considering various options for moving special equipment. We select the appropriate tool and dismantling technology, depending on the type of foundation.

Dismantling methods

The foundation can be dismantled in different ways.

• Manually - using a sledgehammer, crowbar, jackhammer and other devices.
• Using an excavator and other heavy equipment.
• Using special chemical compounds.
• With the help of an explosion.
• Ultrasound.
• Hydrocline.

For private houses, the first two methods are most often used. The manual method is the cheapest, but labor-intensive; you will also need to remove debris from the foundation material of the house. You can try to do it yourself, but it is important to decide whether such an expenditure of effort is really profitable, and whether it would be easier to hire a team of workers. Using an excavator, you can dismantle the foundation easily and quickly; the debris will be immediately loaded into a special container or truck body.

Demolition of a house by explosion can only be used when there are no other buildings nearby, in addition, its cost is quite high. This method is recommended for monolithic bases in the form of a slab, which will be very difficult to disassemble manually. Only specialists should carry out blasting operations; if the technology is not followed, this method can cause harm to both buildings and people.

Special chemicals that are poured into holes drilled in the foundation are also not cheap, as is the use of ultrasound. These methods are safer and do not produce unnecessary noise. After using chemicals or ultrasound, the concrete crumbles into small pieces that are convenient to remove. Also, these methods do not cause harm to neighboring buildings.

Hydrocline

One of the recommended methods is the use of a hydrocline (concrete breaker). This tool is small in size and does not emit dust or unnecessary noise when used. The hydrocline acts in a targeted manner; when used, harm to surrounding buildings is excluded.

The principle of its operation is a strong tensile effect on the structure from the inside. The working part of the hydrocline is spacer frames. Between them, a liquid is supplied under pressure, which stretches the concrete to the sides and breaks it. Using a hydraulic wedge, you can break concrete structures indoors or where it is impossible to bring equipment or carry out blasting operations. To install the tool, a hole is drilled in the concrete, the diameter of which depends on the brand of concrete breaker. Then the tool is inserted into it. How a hydrocline works, watch the video::

The disadvantage of this method is its high price, but it is the fastest way. The hydrocline is capable of breaking slabs several meters thick.

When is it profitable to dismantle the foundation yourself?

You can disassemble the foundation of a house with your own hands if its area is small, if the foundation is strip, pile or columnar. However, in these cases, it is better to consult a specialist before starting work.

Dismantling the foundation of a house yourself will not always be cheaper than ordering such a service from a specialized company or hiring a team of workers. When calculating future expenses, take into account the cost of purchasing or renting equipment and the subsequent removal of construction waste, as well as the time required. Perhaps for the time you spend dismantling the foundation, you can earn the same or more than the cost of the work of specialists and equipment.

Manual method

It is not always possible to bring an excavator or bulldozer to your home. Let's consider how to dismantle the foundation manually. This method requires a lot of physical effort, as it consists of gradually chipping off pieces of concrete using various tools.

• scrap,
• sledgehammer,
• jackhammer,
• circular saw with diamond blade,
• hammer drill

The easiest to dismantle is a shallow strip foundation. You can disassemble it yourself, this is especially true when the site is located in such a way that special equipment cannot approach it. You can also relatively easily disassemble a pile or columnar foundation; screw piles can be unscrewed with your own hands. Special equipment will be needed here only if there is reinforcement 3 cm thick inside the concrete structure.

Before dismantling the foundation, you need to draw up a work plan, think about how you will get rid of construction waste - debris from the old foundation, and be sure to familiarize yourself with safety precautions. It is necessary to decide which methods and tools will be used. It is necessary that all of them are available at the time the work begins - if you have to buy something in addition along the way, this will greatly slow down the process.

Hydraulic equipment will greatly simplify the dismantling of the foundation. You don’t have to buy it - you can rent it from construction companies or even some stores. A hydraulic hammer easily destroys concrete structures without causing damage to nearby buildings. Hydraulic shears are considered a more modern option. They can cut highly durable concrete, monolithic structures made of reinforced or unreinforced concrete, metal beams and other structures.

To destroy the foundation of a small country house, it is quite justified to use chemical compounds that are poured into holes drilled in concrete. After a few days, they corrode the concrete, and it crumbles into small pieces that are easy to remove. Non-explosive destructive mixtures can also be used. The principle of their operation is that the granules of the mixture, after mixing with water, significantly increase in volume and break the concrete. They are poured into pre-drilled holes and filled with water, as a result of which the concrete breaks due to the pressure of the expanding substance. You can also remember the ancient method - wedges made of dry wood are driven into holes in the foundation and watered over them. As they swell, they tear apart the concrete.

Saving an old wooden house: repairing or replacing the foundation

You can determine whether a foundation needs repairs by taking just one look at it. The fact that the days of the foundation of the house are already numbered is indicated by the skew of the building, cracks on the walls and subsidence of the house.

It is impossible to insure a building against such deformations, because over time the foundation materials deteriorate.

Therefore, one day the time comes when the owners of a wooden house have to decide what type of repair to do - partial or complete.

Conditions for partial and major repairs

In order to find out the extent of damage to the foundation and determine the necessary measures to restore it, you need to carefully study the current state of the foundation and identify characteristic defects that may affect the strength and integrity of the building or its individual elements.

If cracks appear on the foundation, then you need to think about the need to repair it.

The foundation is restored in fragments if it has sunk lower but has not begun to collapse. Complete repairs are resorted to when cracks and other damage are detected.

The decision on what basis to replace a completely damaged structure is made taking into account the type of soil, the terrain and the type of foundation originally created.

If the foundation of the house has sunk into the ground, it’s time to repair it

With a strip base, they often proceed as follows: the destroyed areas are dismantled and the structure is reinforced along the entire perimeter. In case of serious damage to the foundation strip, it is decided to completely replace it.

If there are serious defects in the strip foundation of a house, it makes sense to think about its complete replacement.

Repair of a columnar foundation is almost always carried out completely: all the old supports of the building are replaced with new ones. To do this, the house is raised to the height of the pillars using jacks. New reliable supports are fixed on reinforced concrete “pillows”.

The columnar foundation is most often completely replaced with a new one

A wood foundation that has already been slightly damaged by fungus is usually replaced with a strip or columnar structure. To do this, the building is raised to a certain level and concrete blocks or bricks are placed under it.

Strengthening the foundation of a wooden house

When repairing the foundation, it makes sense to immediately strengthen it. This can be done if you are confident in the stability of the soil, which is below the foundation level of your house.

Strengthening the structure under the building may also be required in the case where it is planned to add another floor to the house, but there is a suspicion that the previously installed foundation will not withstand the increased load.

You can strengthen the foundation in two ways, depending on the load it has to withstand.

Instructions for strengthening the strip structure

To make the foundation more durable, perform the following work:

1. A trench is dug along the perimeter of the base. The hole must be wide, otherwise it will be inconvenient to work. In addition, we must take into account that the new foundation will become stronger.
2. The soil is removed from the excavated foundation.
   To do this, use a metal brush. The trench must be wide enough to make it comfortable to work in.
3. Holes are made in the old base with a drill. It is important that their diameter exceeds the thickness of the purchased reinforcing bars by no more than 1 mm. In this case, the metal elements will be installed securely and without gaps.
4. Reinforcement rods are inserted into the drilled holes using a hammer.
   They will help connect the new base to the old one. Reinforcing bars are driven into the drilled holes, to which the vertical grid is attached.
5. Further metal elements are welded to the hammered rods, forming a reinforced belt.
   It is better to solder the reinforcement with already installed rods only in a few places. For the most part, it is wiser to tie metal elements with wire to avoid deformation of the reinforcing belt during pouring and hardening of concrete. The reinforcement cage will firmly connect the old foundation with the reinforcing concrete structure
6. The formwork is installed and filled with concrete.
   After waiting for the solution to harden, the structure of the boards is dismantled. The new foundation is left untouched for several days so that it becomes even stronger. Formwork is installed around the reinforcement frame and concrete is poured into it. After the reinforcing layer has hardened, the formwork is removed
7. The created base is covered with waterproofing material. An asphalt strip is created around the foundation at an angle.

Thanks to the reinforcement, the weight of a wooden building is distributed over a larger area. This method allows you to stop subsidence and destruction of the house.

Replacing the foundation under a timber building

The method for replacing the base depends on its type.

Replacement of strip foundation

Overhaul of the base in the form of a tape is carried out in stages:

1. In order to reduce pressure on the foundation, furniture is removed from the house, floors are dismantled, and the stove is dismantled. Only heating equipment located on a separate concrete platform is not subject to dismantling.
2. The building is raised slightly.
   If the house is small, then its level in relation to the ground is changed using a kind of lever for lifting weights - a beam measuring 8x8 cm, placed at the corner of the building. A log will serve as a support for it. For heavy construction, it is better to choose thicker lumber. The wooden structure is raised by applying pressure to the timber. The house is raised on jacks and temporary supports are placed under it.
3. A trench is dug around the house or only in areas where the wooden building needs to be raised.
4. A jack is placed under the old foundation. There may be several mechanisms for raising a building. The number of jacks is determined by their load capacity and the weight of the house. The mechanisms can only be installed in areas where there is no damage.
5. Using a jack, the house is slowly raised to the desired level.
   It is important that it rises evenly above the ground. Since there is a risk of unsuccessful installation of the jack, it is advisable to play it safe - place wooden wedges between the structure and the base pad. The house is raised evenly on several jacks. For insurance, wooden blocks are placed under the load-bearing beams.
6. The lower crown of a raised wooden structure is tied together with a steel hoop or hammered in with strong boards. This technique will protect the overloaded lower beams of the house from damage.
7. The house is freed from its former foundation right down to the surface of the earth.
   If you are not ready to spend a lot on repairing the base, then you can partially disassemble the structure - remove only the damaged areas. A hammer drill is used to destroy the old foundation.
8. A cushion of sand-cement mixture is made under the reconstructed base of the house. Supports made of concrete or bricks are placed at the corners of the building. Instead, you can use piles. Thanks to the installation of supports, the size of which must correspond to the height of the foundation being constructed, in the future the foundation will be able to withstand increased pressure.
9. Construct a reinforcing belt necessary to strengthen the base. Elements of a metal structure are connected not by welding, but by wire.
10. Formwork is made from boards.
    The finished structure is filled with concrete mortar. Formwork with a reinforcing frame inside is reinforced with side supports and filled with concrete
11. After 3 days, the concrete hardens, so the formwork is removed, but no further work is carried out yet, waiting for the foundation to strengthen.
12. A few days after dismantling the formwork, the new base is covered with a waterproofing sheet, for example, roofing felt.
    A few days after the formwork is removed, the foundation is covered with waterproofing material
13. The house is lowered, acting as slowly as during the raising of the building. The front side of the base is covered with waterproofing and facing materials. A blind area is made around the house, which will not allow rainwater to seep into the foundation.

Repair of support pillars

To replace a columnar foundation, proceed as follows:

1. The house is raised above the old foundation to such a height that it is convenient to dismantle the old pillars and install new ones.
   It is important not to overdo it, otherwise the lower crown of the house may sag. During repairs, instead of a columnar foundation, temporary supports can be installed
2. Pillars damaged by time are removed, and rickety, but still good supports are leveled.
3. In places where new pillars need to be installed, soil is removed.
   A sand-cement cushion is installed at the bottom of the resulting pits. Pillars are placed on it, which are secured with metal rods. New poles are placed at some distance from the old ones
4. The supports installed in the pits are poured with concrete right up to the surface of the ground. When the poured solution has hardened, steel or wooden beams are placed on the pillars, which make the load uniform. After this, the structure is lowered.

If it is necessary to replace just a few pillars, they act differently: they make tunnels in the area where they are located, and pipes are immersed in them and filled with concrete. Old supports are dismantled after the solution has hardened.

Converting a rubble or brick foundation into a monolith

Since the brick foundation is characterized by increased fragility, it is more advisable to replace it with a concrete foundation.

To build a concrete foundation in place of a brick or rubble foundation, perform the following steps:

1. Old masonry made of bricks or rubble stones is dismantled piece by piece.
   Removing every half meter of the structure, first install a jack, and later - metal supports that take on the weight of the building. The old foundation is dismantled piece by piece and metal support beams are installed in its place.
2. A base plate is constructed to install the jack. To do this, reinforcement is laid out on the site and filled with concrete. If the ground under the house is hard, then the jack can be placed on a concrete paving slab.
3. The house is carefully lifted using jacks. Under the lower crown of the building, temporary supports are placed - metal products welded from corners.
4. Installation of formwork begins with the installation of its inner wall and laying the reinforcement cage.
   Next, an external contour is constructed and the resulting space is filled with concrete mortar. Under the new foundation, formwork is made with a reinforcement cage inside and filled with concrete.
5. After the concrete has hardened, the formwork is removed and the house is carefully lowered onto the new foundation.

Repairing the foundation of a wooden house with your own hands

The wooden foundation is mainly made of pine or larch. A wooden structure always requires complete replacement, since over time it becomes completely covered with fungus and rots. Replacing old elements of such a base with new ones is carried out as follows:

1. Using jacks, the house is raised above the old foundation to such a height that it is convenient to carry out work on dismantling old pillars and installing new ones.
   It is important not to overdo it, otherwise the lower crown of the house may crack or sag. The corner of the house is jacked up so that the old pole can be removed
2. Rotten pillars are removed, and rickety, but still high-quality supports are placed straight.
3. In places where new pillars need to be installed, soil is removed.
   The bottom of each base under the support is covered with a 10 cm layer of sand. A concrete “heel” is created on the compacted sand “cushion”. It consists of a layer of cement mortar 20 cm thick. A new wooden pole wrapped in waterproofing sheet is placed in the concrete before it hardens. Before installation, wooden poles must be covered with a layer of waterproofing.
4. The installed pillars are covered with earth and coarse crushed stone. After leveling, roofing material is placed on the supports and wooden beams are placed. The building is lowered onto them.

The damaged foundation of a dilapidated wooden house can be put in order. To do this, you need to obtain the necessary knowledge and choose a repair or replacement technology. You can do the reconstruction of the foundation of a house yourself, if you have the desire and at least a little experience in construction work.

Garbage removal

Dismantling the foundation will not be possible without removing construction waste. You need to decide whether you will do this yourself or contact a specialized company at the stage of planning the work. Small pieces of concrete can be removed without the use of special equipment; larger pieces will have to be crushed first.

Dismantling the foundation yourself is not an easy task, but it is doable. However, before you start work, you should evaluate whether dismantling it yourself will actually be cheaper than turning to specialists for help. Some types of foundations, such as slab foundations, are extremely difficult to disassemble yourself.
