How to pour a foundation for a standing house

Not everyone's home construction begins with laying the foundation. A large number of owners of private buildings bought a plot with an existing house, which was then renovated. But the first thing you need to do is figure out how to make a foundation for an old building, because the functioning of a house is impossible without a solid foundation. You can fill the old foundation to strengthen or restore it, as well as to insulate the house. This article will discuss how to lay a foundation for a standing house and what materials will be needed for this.

Rules for selecting a jack

After the preparatory work, it is also necessary to calculate the mass of the house, this will allow you to correctly calculate the lifting power of the jacks and their number

After the preparatory work, it is also necessary to calculate the mass of the house. This will allow you to correctly calculate the lifting power of the jacks and their number required to lift the building.

You need to calculate it this way:

Repairing the foundation under a wooden house

We calculate the volume of all the walls of the house in cubic meters and multiply by the density of the logs.

Important: the approximate density of a worn round log is 700-800 kg/m3.

To the resulting number add the mass of floors, beams, interior decoration and everything that was not dismantled/removed.

Having determined the mass of the structure that we will lift, we determine the number of jacks. Taking into account the fact that the house will be raised not from one corner, but from all sides for pouring a new foundation, it is necessary to prepare several jacks (from 4 to 6) depending on the length of the walls. Their lifting capacity should start from 5 tons each.

Important: placing jacks in the corners of the house in this case is not recommended, since it is the corners of the future foundation that need to be poured monolithically with a strong reinforcing belt. But jacks won't let you do this. Or use another method of raising the house, which we will consider below.

Creating a foundation under an old house

The procedure for installing a base under an old building consists of the following steps:

digging a trench near a building;
installation of formwork;
foundation reinforcement;
pouring concrete.

Such work is not very complex, so they can be handled without the involvement of specialists.

Digging a trench and installing a support

Experts believe that the optimal distance from the ground to the base of the building is one at which a person can easily fit lying on his back or stomach. To begin the procedure for preparing the site for the base, you will need the following tools:

It is necessary to climb under the building only if it has been decided to pour the foundation also under the internal walls of the house. If the building is small, then digging a hole for the base can only be done from the outside of the building and only along the perimeter. The depth of the trench should be approximately equal to two bayonets of a shovel.

In the resulting pit, it is necessary to install small supports at a given interval so that their lower part rests on the bottom of the pit, and the upper part rests on the base of the erected building. Wood pillars or reinforced concrete columns can be used as supports. With any choice, you will need to use waterproofing materials or special chemical mixtures that will help avoid rotting wood or damage to reinforced concrete structures. The width of the pit should be calculated based on the size of the supporting materials used.

After installing the supporting structures, you can proceed to constructing the bottom of the base. To do this, create a cushion of sand with a thickness of up to 15 cm. This depth is optimal and will allow the base to evenly distribute pressure on the soil and at the same time avoid its cracking.

Stone slabs can also be used as supports.

A good method for compacting sand is to wet it, but then you will need to wait for it to dry.

If the work needs to be done in a short time, you can use a manual tamper.

Creating formwork

Next, the formwork is installed under the building on the inside of the base. For this, low-grade plywood or wooden boards are most often used. In addition, you will need the following tools:

metal fasteners;
hammer;
saw for cutting material;
self-tapping screws;
screwdriver

Simply installing wooden material into the soil around the perimeter of the base will not produce high-quality limiters, since pouring the foundation will simply destroy them. In this regard, the formwork will need to be strengthened by installing additional stops or metal holders, which will ensure maximum efficiency when installed in the corners. You can hammer them in with a hammer or sledgehammer.

Also an important step is connecting the formwork sections. This procedure can be carried out using a screwdriver and self-tapping screws. In addition, a hole must be left in one of the sides of the base. It will be used in the future to pull out the installed formwork walls from the inside, since after strengthening the foundation it will no longer be needed there, but it may be useful for another similar procedure.

The formwork can be left in place altogether, but you need to be sure that the depth of groundwater will not rise and harm the structure. Otherwise, wooden materials will begin to rot and transfer moisture to the concrete base, and from there to the walls of the building. Moisture can also greatly damage the foundation of a building.

If the hole was created outside the foundation, it will need to be sealed decoratively. To do this, you can install a sash or plant a flower bed that will hide the hole.

Base reinforcement

After the installation of the formwork has been completed, you can begin to reinforce the base. This procedure will help strengthen the base and increase its strength. In some cases, when a foundation is being made for a finished house, this stage is skipped. But in order to increase the service life of the building, it is still recommended to perform reinforcement.

To increase the strength of the concrete base, you can use simple steel wire, various metal rods, and gratings. Some experts even use remnants of reinforcement that fit the shape of the dug hole.

After the reinforcement has been completed, installation of the outer sides of the formwork can begin. If there is any doubt that the formwork walls are completely sealed, you will need to stretch several layers of plastic film. This will help avoid pouring out the concrete mixture.

Pouring the base

Many people wonder how to add a foundation to an old wooden house. Fine crushed stone is poured into the existing pit. It will help the concrete solution to distribute evenly and fill all the cracks. Otherwise, voids may form, which will adversely affect the strength and service life of the foundation and the building itself. You need to carefully carry out the procedure for filling the base of an old house; you will need to monitor how the hole is filled and compact the solution as necessary.

Carrying out such a procedure is quite difficult, especially considering that there will be only a small hole between the house and the surface of the earth. Therefore, if you don’t have confidence in your abilities, there are other options on how to lay the foundation for an old wooden house.

In the following video you can see in practice how to lay the foundation for an old house.

Other foundation options for a wooden house

If it was decided to use another method to lay the foundation for an old house, you will need to use other materials. You need to prepare:

Tools will be used similar to those used in conventional foundation construction under a building. The usual method of laying a foundation under a building can take quite a long time, and the process itself is very labor-intensive. Instead, many professionals recommend creating simple brickwork, which is much easier to create and can be fitted tightly to the base of the house. With this choice, there will be no need to install formwork, reinforcement, or add concrete.

For old buildings, different types of foundations can be used.

In addition, this method of installing a base will require much less material, which is a good opportunity to save money. You can use bricks that have already been in use. Unattractive or damaged brick can be decorated with various building materials. For this purpose, you can use siding, tiles or artificial stone.

It would also be a good idea to put a dilapidated house on a pile foundation. It involves installing piles along the entire perimeter of the building directly under the base. Installation is carried out by methodically screwing the piles into the ground until they reach dense soil. Such columns are concreted near the base, after which you need to raise the house using jacks and lower it onto a new foundation. This type of basis is a good solution, and the work to create it can be done fairly quickly.

As can be seen from the article, a house without a foundation does not have the necessary strength, so its installation is still inevitable. Sometimes it also becomes necessary to add base, in which case it is necessary to raise the building. The procedure for laying the foundation for a built house can be performed in different ways, but all of them are not individual.

Preparation for the start of work

If you plan to pour a foundation for a standing house, you need to prepare the following tools:

4 jacks;
Wooden beams or metal fastenings. Their length must exceed the length of the house by at least 1 meter;
Metal or wooden supports on which the house will rest.

In addition, you also need to prepare a concrete mixer, 12 mm thick reinforcing bars, sand, crushed stone, and Portland cement grades M400 or M500.

Stages of work

The foundation for a standing house must be of high quality and reliable. And in order to carry out this work, you need to prepare a work plan, which includes the following points:

Digging a trench;
Installation of supports under the house using jacks;
Construction of the formwork system;
Foundation reinforcement;
The final stage.

Laying the foundation for a house

The work begins with digging a trench for the foundation. If you want to pour a foundation for the interior walls, then you will have to dig up a significant amount of earth to get under the house. The width of the trench being dug corresponds to the width of the installed supports.

When the trench is ready, 15 cm of sand is laid on the bottom, watered and thoroughly compacted. When the sand has dried, you can begin installing removable formwork from unedged boards. We install the boards along the edges of the dug trench and fasten them together with self-tapping screws. To ensure that the structure holds well, we secure the joints with metal posts.

To increase the strength of the foundation, we carry out reinforcement. For this work, we take a steel grate, metal rods or thick wire. We fasten all the elements together by binding or welding, which is more reliable.

The foundation for a standing house is a responsible job and you can’t do it without helpers. Now it's time to begin finishing work on the foundation. We fill the trench with fine crushed stone, and then concrete mortar prepared from:

1 part Portland cement;
3 parts sand;
2 parts crushed stone.

The components are thoroughly mixed in a concrete mixer and then poured into the formwork. In this case, it is necessary to additionally lay several reinforcing bars at the bottom and top of the formwork. Next, we wait until the concrete solution sets well and hardens, we take out the formwork and fill the vacant space with earth.

We cover the finished foundation with two layers of roofing felt for better waterproofing. After this, we gradually lower the house raised on jacks to its original place, while pulling out the support beams one by one very carefully. Your home should sit firmly on the new foundation.

Before laying a foundation for a standing house, be sure to check the bearing capacity of the soil, as it plays an important role in the strength of the entire structure. Remember that at least a month must pass from the moment the concrete is poured until it is loaded. Filling is carried out at a temperature not lower than +5 degrees.

And lastly, never save on building materials for the foundation, since you will have to deal with low-quality material or incorrect work in the near future. And it will be a shame for wasted money and time.

Ways to jack up a house

So, if there is only one jack and its lifting power corresponds to the weight of the house, then you can lift the building a little on each side

To pour a new foundation, you only need to lift the house with a jack. This method is quite effective and, although it takes more time, unlike lifting the building with a crane, it causes less damage to the structure itself.

You can raise the building with your own hands step by step from each side or simultaneously from all sides.

So, if there is only one jack and its lifting power corresponds to the weight of the house, then you can lift the building a little on each side. To do this, install the device at the designated point of the house and raise the building by 2-3 cm. Place a support under the resulting space and move to another lifting point. This way you can raise the building to the desired height.

Important: this method is quite dangerous, because with minor differences in height, the walls of the house may not withstand the load and simply break. Especially when you consider that the height difference in the crown area of 1-2 cm at the level of the ridge is already 5-6 cm.

Another way to raise a house is to work simultaneously on all sides. In this case, the jacks are installed along the long walls of the house, retreating 60-70 cm from the corners into the wall. If the crown logs are sufficiently worn out and the wall is more than 4 meters long, then additional jacks can be placed in the middle of the walls. In this case, the work must be carried out synchronously, raising the frame by 3-4 cm at a time. In this case, each stage of lifting is secured with support beams or pillars. This method of raising a house is effective and less dangerous for both the log house and the craftsmen.

How to properly pour a foundation for an old wooden house - step-by-step instructions

Sooner or later, any foundation under a house has to be changed or repaired. The house begins to change its position, cracks may appear, and windows and doors jam. All these signs indicate the need for repair or complete replacement of the foundation. In this article we will try to tell you how to properly pour a foundation for an old house without compromising the integrity of the structure. After all, only competent and correct work will give you a guarantee that your house will stand firmly for many more decades. However, in order to take on this matter with confidence, you should carefully understand all the intricacies of this process.

Material and tools required for work

To repair or replace the foundation, it is not always rational to use special construction equipment, and fitting it to the house without damaging other buildings and planting garden crops can also be problematic. Therefore, it is important to know what tool you may need during the upcoming work and prepare it in advance:

Jacks. At least 4 pieces. They can be of any design, but it is preferable to use hydraulic ones. When choosing them, it is important to take into account that they must lift a load weighing at least 10 tons, therefore, they must be able to develop sufficient force. If you don’t have them in stock, then it would be wiser to rent them than to spend money on purchasing them;
Sledgehammer, steel crowbar or jackhammer;
Wedges of various sizes;
Temporary supports, which can be used as bricks, massive beams, durable boards of various thicknesses, metal beams or chocks;
Panels made of beams or boards measuring at least 250 square meters. cm, which will serve as the basis for the jacks;
Steel plates about 5mm thick. so that the force from the jack rod is evenly transmitted to the lower crowns of the building;
Concrete mixer. It will be needed to prepare cement mortar. If the volume is large, this will be difficult to do manually;
Reinforcement, the thickness of which will be at least 12mm;
Materials for mortar: cement, crushed stone and sand. Their number depends on the size of the foundation;
Waterproofing materials.

The order of work and the features of each stage

Replacing the foundation or repairing it does not accept haste and haste; everything must be thought out to the smallest detail. Before starting work, it is necessary to find out the bearing capacity of the soil and the depth at which groundwater lies.

Neglect of these parameters will lead to the fact that the new foundation will quickly become unusable, since it will be subject to strong pressure from the frozen soil. Based on the data obtained, a calculation is made of the depth of the foundation and the features of its installation.

Scheme of pouring the foundation for a house

Lifting a house from its foundation

In order to avoid problems at this stage, you need to start work by making supports for the corners of the house. They begin lifting the house from the most sagging corner. Using two jacks, evenly understand the angle on both sides.

It is recommended to raise the angle no more than two centimeters, otherwise multiple cracks may occur. Every 5mm. When lifting, blocks are placed to protect against malfunction of the jack.

Raising the corner of the house from the foundation. 1 - lower crown of the frame, 2 - lever made of boards, 3 - support for the lever, 4 - old foundation

On the outside of the house there will be a jack on the inside, a support made of bricks. To do this you will have to lift the floorboard;
The jack and support should be installed as close to the foundation as possible, this will reduce the load on the lever. Don’t forget to lay out a brick platform under the base of the jack;
A metal channel or beam can serve as a lever for raising the corner of the house;
We begin lifting with slow movements of the jack handle. The main thing here is to prevent the outer end of the lever from sliding off the jack platform, so every 2-3 pumping check whether everything remains in its place;
After raising the corner, it is necessary to place supports in the resulting gap. They must be placed on stable surfaces.

Pricing and labor intensity of the task

The price of work for raising a house depends on the type of house and its height.

Prices:

1. Raise a 6x6 frame house with exposed floors and without internal supports - from 35,000 - 45,000 rubles

2. Lifting a timber house or a 6x6 log with exposed floors and without internal supports - from 40,000 - 50,000 rubles

3. The presence of a veranda, porch and other outbuildings – + 7,000 – 13,000 rub.

The difficulty of lifting an old log house onto its foundation lies in the danger of the work.

If the owners of the facility have taken care of the preliminary stages of preparation in advance, then the work will be easier, faster and more reliable.

It is recommended to evaluate the object completely - the visible problem is not always the only one.

The approximate price of additional work is as follows: Lifting and leveling a blocked corner - from 9,000 rubles

Raising/leveling the wall of a large house - 20,000 rubles. Dismantling of house cladding - from 200 rubles m2. Raising a house up to 40 cm – price without additional factor. Lifting up to 1 m – price with additional charge. coefficient + 100%. Raising a two-story log house - from 100 thousand rubles.

The cost of each process depends on the scale of the work, full or partial lifting, and the architectural features of the building. It is more expedient and more economical to order a full range of services for raising the house, restoring or replacing the old foundation.

How to make a foundation for an old house without a foundation

Residents of private houses are very often faced with the problem of carrying out constant preventative and repair work, which allows the existing building or several buildings on the site to serve for a long time and conscientiously. Almost no season can go by without patching up the roof, painting the fence, or strengthening the foundation. Of course, an initially well-built foundation will last for several decades before requiring repairs.

However, not everyone makes a home from scratch. And not everyone’s construction of private property begins with laying the foundation. The fact is that a significant part of summer residents and residents of suburban settlements often buy a plot with an old house on it, which is restored over time. And this matter is extremely complex. The very first question is how to make a foundation for an old house. After all, without a foundation, even a veranda cannot function, not to mention a living space.

A new foundation is poured not only in cases of its absence, but also to strengthen the existing or dismantled foundation, to improve the appearance of the building, to insulate the space directly under the house (basement, subfloor, ground floor) and in many other cases.

What does replacing the base with screw piles give to a wooden structure?

Wood is an environmentally friendly natural material that provides comfortable living in the summer heat and severe frosts. Wood retains heat well and allows walls to breathe. But if used improperly, mold can form on the wood, which leads to its rotting. This is especially true for the lower crowns of the building, because they are the ones who experience the flow of rainwater, temperature changes and the colossal pressure of the entire building. This has a detrimental effect on the wood material and leads to its deformation.

Raising the foundation of a wooden house will solve the problem of wood damage, because when using screw supports, the height of the base depends only on the wishes of the customer. As a result, the tree will be ventilated, which significantly increases its service life. In addition, replacing the base with a pile-screw one by raising the foundation of a wooden house will improve the structure and give it a new look. The pile-screw foundation is not afraid of soil heaving and loose soils. After all, the support, going deep into the bowels of the earth, passes through all the unfavorable layers of the soil and ensures the strength and stability of the foundation.

Installation under an old house

Diagram of a strip foundation for a house.

A very successful option for organizing an old house is when the distance from the ground to the base of the house allows a person to easily fit while lying on his stomach or back (this is necessary for repair work). In this case, you need to dig a trench from the outside of the house being finished, the depth of which should not exceed the bayonet of a shovel. After some distance, we install small supports under the base of the house. They can be wooden posts or reinforced concrete columns. The width of the trench must be equal to the width of the supports used. After the trench around the entire perimeter of the house is ready, a sand cushion approximately 10-15 cm thick needs to be poured onto its bottom. This will be enough so that the created foundation evenly loads the soil and does not crack under the weight of the house standing on it.
