Finishing the base with corrugated sheets

During operation, the foundation is exposed to various negative factors and at the same time takes on quite large loads, transferring them to the ground. At the same time, the foundation must retain heat in the house and prevent moisture from penetrating into the basement.

At the level of these requirements, the aesthetic side fades into the background, but you should not neglect the finishing of the base. Firstly, each base has a part that is located above ground level, so its appearance must be consistent with the overall exterior. Secondly, the cladding of the base is a kind of protection of this part from the influence of a large number of external aggressive factors.

The finishing of the base can be done with any material, including brick (we have a detailed article about the brick base), natural stone, siding (we previously wrote about installing basement siding on the foundation) or polyvinyl chloride panels. However, when choosing a facing material, the consumer gives preference to an option that combines strength, aesthetics, durability and reasonable cost. All these requirements are met by profiled iron sheets.

What is the difference between corrugated sheets and corrugated sheets?

Corrugated sheeting is often confused with corrugated sheets and vice versa. These materials are similar in the manufacturing process. They are produced by cold rolling of steel sheets with a galvanized coating, which reliably protects against corrosion and destruction. The external resemblance is obvious.

Profiled sheet

Corrugated sheet

Main differences:

rigidity,
scope of application,
profile height,
variety of colors and designs to choose from.

Corrugated sheeting - used most often as a roofing material, has a more pronounced profile, which gives the material additional rigidity. The finishing corrugated sheet has a profile height of less than 3.5 cm. Profiled sheets are presented by manufacturers in various colors, shades, sizes, which cannot be said about corrugated sheeting.

Advantages of corrugated sheet cladding

Today, the base is increasingly made from corrugated board, since this material has a number of important advantages in this case.

Strength that will protect the lower part of the house from various external factors.
Durability - if you cover the base with corrugated sheeting with a high-quality polymer layer, it will serve for more than 50 years, maintaining its attractive appearance and contrasting colors.
Low specific gravity, which ensures ease of installation.
Aesthetics. The bright polymer decorative and protective coating allows the corrugated sheet to be perfectly combined with any other materials involved. The variety of shades (1,500 colors in total) allows you to find the one that will most harmoniously fit into the exterior.
Such a base can be ventilated, which will allow the structure to be insulated with both artificial and natural insulation materials made from mineral fibers.
Democratic price. The material is made from a not particularly thick layer of metal, and therefore costs several times less. If desired, you can even use substandard corrugated sheeting, which is sold cheaper than usual. This includes the remains of large batches, products that do not meet any new requirements, sheets with defects, or damage to the metal base. The main thing is that the polymer layer is intact.

What type of material is used?

The base is sheathed with a certain type of corrugated sheet . Any material will not work here. Sheets for finishing the base part are designated “C”. This material has the required strength characteristics and resistance to temperature changes.

If the markings are with the letters “N” or “NS”, then they are not suitable for finishing work on the walls. The sheets are too strong, which leads to higher prices.

The “C” marking is followed by a number indicating the height of the ribs, for example:

S8,
C10,
S20,
C21.

The higher the height, the greater the strength. Next comes the thickness, the standard value of which is 0.4 ÷ 0.8 mm.

The choice of sheet depends on the purpose of its use . For finishing external walls, installing fences, C8 (budget, with a sheet thickness of up to 0.7 mm) is suitable. If the roof is covered and insulation is added, then C10 is used (up to 0.8 mm).

For finishing the base, C13 is selected, with a thickness of up to 0.7 mm and a ribs height of 1.3 cm.

Technological features of finishing with corrugated sheets

Before sheathing the base of the building, it is necessary to prepare all the necessary tools and materials and take measurements.

List of tools

To perform the work technologically correctly, you will need:

profiled sheets 0.6 mm thick;
clamps for metal profiles;
guides, dowels, corners, screws;
grilles for creating ventilation;
cutting tools: grinder, scissors, hacksaw and hammer.

Corrugated sheets can be installed only after the construction of the sheathing is completed.

Selection of building cladding material

Sheathing the foundation with corrugated sheets is not so difficult. For work, you can take a corrugated fabric marked C (wall). Manufacturers produce material with a corrugation height of 8-21 mm. The following sheet modifications are distinguished:

with textured embossing for finishing the exteriors of luxury buildings;
with a polymer coating - a protective layer on the surface;
hot-dip galvanized - an economical option for the construction of fences;
uncoated - a budget material that requires periodic paint treatment.

To increase the service life of the cladding, hot-dip galvanized sheets are embossed and a polymer layer is applied. In ventilated areas that are in drafts, corrugated sheets for foundations grades C8 - C10 are used. For buildings near which snowdrifts constantly form in winter, it is better to use sheets of increased rigidity - C13 - C21.

Which coating should you choose?

The metal sheets are treated with zinc coating, followed by finishing:

Polyester – thickness up to 25 microns . It is based on an artificial substitute for tree resin. It prevents cracking, destruction, and burning. The disadvantage is poor protection against mechanical damage, which contributes to the development of corrosion.
Matte polyester is a thicker coating with a textured pattern that imitates natural material.
Puralom – high strength, quality, allows the use of profiled sheets in regions with excess humidity.
Plastisol – the coating imitates wood and stone. It withstands the influence of snow, water, dampness, and mechanical damage.
PVDF - has increased strength, reliably protecting the entire surface of the material. Operational warranty up to 40 liters.
Printech coating with a complete imitation of the surface of natural stones, bricks, and wood. It is considered the best coating for corrugated sheets for cladding the basement of houses.

Existing brands

The brand of wall corrugated sheet is chosen depending on the designation. "C" stands for wall material. "NS" is universal. Other designations have increased strength indicators and increased thickness, which makes the use of the material impractical and too expensive. The finishing of the base part and its durability depends on the height of the rib profile.

The most suitable options to prevent the surface from destruction and mechanical damage:

S8,
C10,
S20,
C21.

Standard sheet sizes:

width – 1060-1200 mm;
length from 0.5 to 10 m;
wave height no more than 15 mm;
thickness – up to 0.8 mm.

Execution options

The sheet profile differs in wave height, thickness and purpose of the material:

“N” - load-bearing, has high strength characteristics.
“C” - wall (suitable for finishing wall surfaces, plinths).
“NS” - universal (also suitable for the base part).

The choice of color, geometry, wave height, and shape depends on:

owner's taste
general house design,
garden territory.

Relevance of plinth cladding

The process of installing the cladding
The base part of the building is the lower visible part of the wall, which plays an important role in the process of uniform distribution of the load and is most subject to the harmful effects of environmental factors, each of which, to one degree or another, leads to the gradual destruction of the foundation. Based on this, any prudent home owner, striving to keep his home in decent shape and provide it with the most reliable protection, sets himself the task of protecting and insulating this important element of the residential structure.

Tools and materials for sheathing

Before choosing the right material and counting them, it is necessary to take measurements, decide on the overall design and color scheme. You need to choose the option you like, clarify its dimensions and then start making calculations.

Having the necessary tool listed below in the article will not be superfluous. Its purchase is an additional expense.

Before purchasing or choosing materials for construction, you must consult with experts about the parameters of the profiled sheet you like, its service life, reliability, and preservation of appearance.

Don't skimp on quality . The better the material and its processing, the longer it will last while maintaining the characteristics declared by the manufacturer.

What is low tide and what are its functions?

Since the foundation performs a load-bearing function, it is often wider than the walls. Therefore, the base forms a protrusion relative to the walls. Melting snow or rain moisture can accumulate on the top of the foundation and gradually penetrate deeper, eroding the structure of the base of the building. In addition, when freezing, water that gets inside the base expands, also having a destructive effect.

To prevent such processes, a bar is installed on the ledge, the width of which can be from 5 to 40 cm. It is mounted on the base at a slope, which allows water to drain. This is the low tide.

Base ebb

In addition to being protective, such a canopy performs a decorative function, participating in the design of the facade of the building. It is made from various materials in various colors.

Planks can be of different shades

Note! The color of the tint can not only match the tone of the facade or base, but also be contrasting. If you choose the right palette, this option will decorate your home.

Calculation of the required quantity

Calculating the required amount of material is not a difficult, but responsible task. It is necessary to carefully measure the area of the plinth. Calculation procedure:

Calculation of foundation area .
The width and height on each side are measured and their area is found. Next, all areas are summed up. A standard house is a rectangle, which means to find its area you need to multiply the width by the height, and so on on 4 sides.
The total area is the sum of the 4 sides of the house. It is most convenient to make calculations in meters, so as not to later get confused in converting units of measurement.
Purchase of materials . Knowing the dimensions of the base, you can easily select the necessary profiled sheets in a hardware store. Prices for material are indicated in sq.m., which is convenient in calculations.
Increase for additional expenses . To the resulting amount you should add 10-15% for unforeseen situations, since it will not be possible to take everything into account. This increase will help out in case of force majeure, especially if the house is of non-standard design.

Frame installation technology for sheathing with corrugated sheets

Frame installation diagram for sheathing with corrugated sheets.

The lathing for sheathing with corrugated sheets can be made from either a metal profile or wooden blocks. For vertical racks use a U-shaped profile 60/27 or 50/50. The first option will be optimal. since this will make it possible to install the profile in the PN 28/27 guides. If you decide to make a frame from wood, then take bars 30/40, 30/50, 50/35.
The profile or bars are attached to the base using dowels and hangers. At the same time, the foundation is leveled vertically and horizontally.
The pitch of the vertical posts should be 40-60 cm.
If a metal profile PP 60/27 is used to cover the walls with corrugated sheets, then it is recommended that the upper and lower ends of the racks be strengthened and leveled using guides fixed in a horizontal position. This will give the frame a more strict and regular shape.

How to sheathe it yourself?

Before starting work, you should prepare the necessary materials, tools, calculate and purchase the required number of profiled sheets. Profiled sheets are mounted on the finished surface of the house. The work can be completed independently, having everything you need available.

Tools:

Level, roulette.
Marker for making marks (black, white).
Self-tapping screws for assembling parts and fastening them.
Bulgarian.
Screwdriver, screwdrivers of the required sizes.

How to make cladding with corrugated sheets around the base of a house? Main stages:

Preparatory. Preparation for finishing implies the presence of waterproofing, the absence of cracks and depressions. Cleaning the surface from dust and dirt.
Marking . Markings are applied across the entire area of the base, where the frame will go, and the attachment points, depending on the size of the profiled sheet. To do this, use a level, a rope, or a special marker. Perpendicularity and parallelism to the line must be maintained so that the structure looks beautiful and stylish from a design point of view.
Installation of metal frame structure . Installation of a metal frame, its dimensions depend on whether or not additional waterproofing and foundation insulating materials will be installed. The profile is installed at a certain distance (no more than 40-50 cm) for convenient fastening of profiled sheets.
Installation of insulation, waterproofing materials , if necessary.
If the base needs to be insulated or waterproofed, then this should be taken into account when choosing profiled sheets, calculating areas and installing a metal frame. In order for the profiled sheets not to allow moisture to pass inside, the base must be waterproofed, i.e. The concrete foundation is subject to special treatment.
Thermal insulation is ensured by using basalt mineral wool and polystyrene foam, which are mounted from bottom to top. All components must be sealed.
Fastening the profiled sheets .
Upon completion of the preparatory work, you should proceed to fixing the profiled sheet. Its installation starts from the left corner, moving towards the right. As the sheets are fixed, you need to constantly check the surface with a level for evenness. If even one part is laid unevenly, this will lead to displacement of the entire surface, resulting in a deterioration in the overall appearance. The first corrugated sheet is secured with a roofing screw with a press washer and its surface is leveled using a level. The fastening step is through 1-2 waves to the lower parts. Each subsequent sheet is laid overlapping the previous one, which allows you to achieve the effect of naturalness of the material. The joint area is reinforced with rivets. For one sheet 3 pcs.
The final stage, finishing work . Once all the work is completed, finishing should be carried out to remove unnecessary gaps and irregularities to give the house a spectacular appearance. For this, finishing strips, corners, and ebbs are installed.

If there are chips, scratches, or cracks, they are painted over with a special paint that matches the color of the profiled sheet.

Waterproofing and insulation of the basement

Before making the sheathing on the foundation, the base should be insulated and protected from moisture. This is done using the following methods:

thermal insulation is carried out with extruded polystyrene foam or basalt wool, which is used to cover the horizontal top edge and the entire vertical surface of the base;
waterproofing is applied to accessible concrete surfaces. The gluing, coating or plastering type is used;
sealing of junction points to the blind area plinth. This is done with a special film, hydroglass insulation or membranes, which are attached over the insulation to the purlins and run through the cladding.

Waterproofing will optimally quickly and effectively protect the foundation from destruction.

Average prices for materials and labor costs

Average prices in Russian cities for professional sheets and work:

Moscow, Moscow region - from 400 rubles/m2 for work, which includes installation of insulation from 90 rubles. per sq.m. Purchasing the material will cost from 200 rubles. per square meter;
St. Petersburg - from 150 rubles. per sq.m. material, work will cost from 350 rubles;
Kazan - the material costs from 200 rubles/m2, you will have to pay for the work as in St. Petersburg.

The price for the building materials needed to close the basement is approximately the same across cities, since they can be purchased not only in large hypermarkets, but also ordered online.

The cost of work in big cities is higher, due to high demand and high wages, compared to peripheral regions.

Profiled sheet for decorative stone for plinth

Cladding the base with a profiled metal sheet to look like stone is a fairly common method of finishing the lower part of the house, which stands out among others (plaster, tiles) due to its low cost, ease of installation and good performance characteristics. The modern building materials market offers a wide range of sheet materials, among which the leader is corrugated sheeting of various colors and textures. The popularity of this material is also facilitated by the possibility of applying any print or texture, which increases the visual appeal of the finished structures.

Pros and cons of using

The main advantages of the profiled sheet include:

High strength indicators. The sheets are made by cold rolling, which gives them additional strength.
Long service life. The material is not subject to corrosion or destruction.
Large selection of colors, geometries, shades. The variety of choices allows you to choose sheets to suit any design of your home or garden.
Easy installation. Basically, the cladding is done in-house, since the material is easily cut and attached to the surface.
Availability. The main advantage is that it allows you to get a good appearance of your home at low cost.

Disadvantages include instability to mechanical damage. If the surface protective layer is damaged, the material quickly rusts and collapses.

Tools and accessories

A high-quality screwdriver is indispensable during installation.
Arranging the basement floor cladding does not require special skills and abilities, so it can be easily done with your own hands. For high-quality and prompt installation of corrugated sheeting, it is enough to prepare the following simple tools and consumables, which can easily be found in every home:

screwdriver or drill with bits of the appropriate section;
hammer drill (for drilling holes in the base for mounting brackets);
construction tape and level;
felt-tip pen or marker;
scissors or saw for cutting metal and profile beams;
Bulgarian;
rubberized hammer.

When preparing the tool, it is important to take into account that the use of electrical equipment will significantly reduce the time spent on installation; however, if it is not available, you should not purchase expensive devices, but it is more advisable to use alternative manual devices.

Cutting corrugated sheets

Finishing the base with corrugated sheets begins with the preparation of all sheets, which must be fully suitable in size. To do this, the first thing you need to think about is how much and how high the layer of corrugated sheeting on the base will be. To cut the material you will need a grinder and scissors for cutting metal.

When working with metal scissors, the cut will be smoother. If you prefer an angle grinder, then you need to choose thinner wheels. It is best if the disk has a carbide coating. After the sheets are cut, it is very important to treat the edges with a paint and varnish composition, otherwise in the future, due to burrs, rust will form on the entire surface of the sheet.

In general, it is recommended to use metal scissors. Yes, the process in this case will slow down somewhat, however, the edges will be smoother, and additional work will not be required.

Ideally, you need to select sheets in a hardware store whose dimensions are best suited for your base.
