Finishing the foundation with a profiled sheet

Plinth plating can be done with any finishing material: brick, siding, natural stone or PVC panels. Recently, however, consumers increasingly prefer iron corrugated board, which combines durability, aesthetics, exceptional strength and affordable price. How to properly veneer the basement from the outside with a profiled sheet - we will tell you in our article.

During the operation of the structure, its foundation is daily exposed to external adverse effects. It takes enormous power loads. In addition, the task of keeping heat in the house falls on the foundation. And of course, the general appearance of the basement must certainly correspond to the style of the building's facade.

When using corrugated board for cladding the foundations of buildings, they resort to the facade ventilation technique. Thus it is possible to ensure optimal thermal protection of the subfloor and significantly reduce the heat loss of the supporting structures. With the help of corrugated board, you can decorate the basement, as well as finish the pick-ups of the basement zone in buildings on columnar or pile-type foundations.

Its advantages are undeniable:

• long operational period;
• the high quality of the polymer coating determines the strength and richness of color, which persist for up to five decades;
• the profiled surface provides increased bearing capacity;
• does not support combustion;
• is resistant to aggressive environments;
• quick and easy to assemble.

In addition, profiled metal has decorative look. In stores, you can buy models of a wide variety of colors - modern manufacturers select shades in strict accordance with the RAL catalog, which includes about 1500 tones.

It is possible to cover the plinth with corrugated board all year round. High quality canvas reliably protects concrete and stone elements from adverse conditions and allows them to maintain their original technical and operational characteristics for many decades.

However, there are also disadvantages:

• heat and sound conductivity - sheathing of basement structures with a profiled sheet is desirable to be performed on top of the insulating layer;
• vulnerability of the polymer layer - any scratches should be painted over with polymer paint of the appropriate shade as soon as possible, otherwise oxidation and, as a result, corrosion may begin;
• low efficiency - associated with a large amount of waste after cutting the profiled sheet.

When buying a profiled flooring for arranging a basement area, one should be guided by the marking of the offered products.

• The presence of the letter "H" indicates the high rigidity of the finishing material. These sheets have found their application in the arrangement of roof structures. In plinth plating, they are rarely used due to the high price.
• The letter "C" means a material in demand for wall decoration. This profiled sheet has sufficient flexibility, thanks to which it is popular when sheathing solid foundations. When used for foundations, it requires a reinforced, solid frame.
• "NS" - such marking indicates a corrugated board intended for sheathing of vertical surfaces and roofing. The technical and operational parameters and the price of this material are approximately in the middle between the similar indicators of professional sheets of categories "H" and "C".

The numbers immediately following the letters indicate the height of the corrugation. When selecting a facing material for the foundation, the C8 parameter will be sufficient. The next marking symbol indicates the thickness of the profiled metal, which affects the bearing parameters of the entire material. When it comes to the finish of the base, this characteristic does not play a key role - you can focus on the 0.6 mm indicator.

When choosing profiled sheets for arranging basement structures, special attention should be paid to the quality of the protective coating, its design and color scheme. There are the following modifications of professional sheets:

• embossed - are in demand when finishing the facades of elite buildings;
• polymer coated - assume the presence of a durable protective layer on the surface;
• hot-dip galvanized - economist, most often used for the construction of enclosing structures;
• without cover - such a professional sheet is used in conditions of a limited budget, it will require regular processing with paints and varnishes.

For sections of buildings located in drafts, the best choice will be a professional sheet of grades C8 – C10. For houses near which snow drifts constantly accumulate in winter, it is better to use corrugated board of increased rigidity. This requirement is met by products marked C13-C21.

To independently install the profiled metal plates, you need to prepare working tools:

• building level - it will allow you to mark the basement surface;
• plumb line - necessary for verifying the verticality of the main structural elements;
• felt-tip pen / marker;
• ruler / tape measure;
• puncher;
• screwdriver;
• drill with drills;
• a tool for cutting metal blanks.

To prevent excessive spending of funds, it is necessary to calculate as accurately as possible the amount of material that will be required to carry out the work. In the case of corrugated board, as a rule, there are no difficulties, since their installation involves fixing rectangular metal sheets to a vertical surface. Nevertheless, some points still need to be taken into account.

• To simplify calculations, it is desirable pre-draw a diagram placement of sheet material and brackets.
• Fixing the slabs can be horizontal, vertical or cross, this can affect the number of brackets used in finishing. Therefore, you need to decide on the placement of the panels before going to the store.
• When calculating the total area of ​​the basement of the building, placed on the ground with a slope, you must account for the variable height in this area.
• You need to select sheets so that minimize waste after cutting.

You can improve the external decorative characteristics of the foundation areas located above the ground, and additionally create protection against adverse influences with your own hands. To do this, you must adhere to the installation technology.

After completing the basic calculations, purchasing tools and cladding material, you can go directly to the plinth trim. At this stage, all work is carried out in a given sequence, that is, step by step.

Before installing the battens on the foundation, its base must be protected from water. Waterproofing is applied to all exposed concrete surfaces. Usually, for this, the coating type is optimal, a little less often - the plastering type of treatment.

Special attention should be paid to the nodes of the junction of the blind area to the plinth - in this place, waterproofing is carried out with hydroglass, a special film or membranes. They are placed on top of the insulation board on the purlins, and then run through the cladding. These simple measures will effectively protect concrete from destruction due to the effects of precipitation and underground moisture.

Next, you need to mark the surface to be sheathed and calculate the location of the main load-bearing elements of the sheathing. It should be borne in mind that the step between the guides should be 50-60 cm... In addition, door and window openings, as well as the corner parts of the basement, will require separate brackets - they are fixed at a distance of up to 1 m from the corner part. According to the marks given, holes should be drilled, it is advisable to use a perforator for this. The length of the hole must exceed the size of the dowel by 1–1.5 cm. However, it should be borne in mind that if the base is made of brick, then it is not recommended to drill the seams of the masonry.

The holes are thoroughly cleaned of dirt and construction dust, and then the brackets are attached. For uneven foundations, brackets with moving parts are the best solution, they can be moved and fixed at the desired level if necessary. To begin with, the brackets are fixed at the edges of the basement area. Subsequently, they are connected to each other with a construction cord and form a certain level for mounting intermediate brackets.

Warming of the foundation is carried out using basalt or glass wool, as an option, you can use extruded polystyrene foam. They begin to work from the bottom, moving up. First, slots are formed in the insulation to accommodate the brackets, then the plates are pushed onto the brackets and fixed with disc teeth, their number on each plate should be five or more pieces.

The fixation of the profiled sheet directly is performed using rivets and self-tapping screws. For each square meter, you will need about 7 pieces. Installation of sheets is carried out vertically, starting from one of the corners. Sheets overlap one or two waves - this will ensure maximum strength and sealing of the structure. The sheet is fastened with self-tapping screws from the outside, in the deflection of the corrugation. The lathing in the joint areas of the canvases is closed with specialized corners. Please note that the fasteners should not be tightened too tightly, otherwise dents will appear on its surface.

During installation work, remember about the arrangement of the ventilation system. The holes in the panels must be prepared in advance, in order to close them, you need to buy special grilles - they are sold in any building supermarket. They will not only improve the external characteristics, but at the same time prevent the penetration of dirt and dust into the skin. The fixation of the product is carried out using mastic, and the gap between the ventilation grill and the canvas is sealed with silicone sealant.

At the end of the work, you should arrange the corners using a decorative finishing strip... If during the installation of the profiled sheet the surface of the material is damaged, then all chips and scratches must be covered with an anti-corrosion compound, and then painted in one tone with the canvas around. The foundation of a private house, finished with profiled sheet, provides reliable and at the same time budgetary protection of the structure from destruction.
