Одним из распространенных способов теплоизоляции The foundation of today is the use of penoplex, which is a polymeric material having a closed cell structure. At 98% it consists of air, which, as we know, is the best heat insulator. Working with the material is quite simple due to its low weight.
This insulation for the foundation has a lowwater absorption, which is 0.5% of the volume during the lifetime. Closed cells are filled with air, which acts as an excellent heat insulator. Due to its water-repellent characteristics, the material retains its properties in arbitrarily difficult conditions, it is not susceptible to destruction when the internal moisture freezes. If you want to make insulation of the foundation with a penoplex with your own hands, then you will need to purchase material that is produced in the form of slabs of different thickness. Products may have mounting slots that allow the use of thermal insulation with maximum efficiency. You can strengthen it quickly, eliminating the formation of cold bridges, seams and gaps.
If you decide to use the described heaterfor the foundation, you can take one of the existing technologies as the basis of the work. Thus, the insulation can be vertical, while protecting not only the foundation itself, but also the basement. Such manipulations are carried out, as a rule, from the outside of the building, the space inside the house and the wall of the foundation falls under protection, which significantly increases the life of the building.
Penoplex, whose thickness is usually50-100 mm, is installed on the prepared surface with the help of polymer-based adhesive or cement. When installing the material in the basement part of the plate, it will be necessary to additionally fix it with special dowels. Horizontal warming of shallow strip foundations presupposes protection of structures against freezing and against the impact of tangential forces of frost heaving. For the work of the slab it will be necessary to lay under the foundation base.
If you decide to make basement insulationdo it yourself, then the technology can provide for the formation of a blind area around the house, which is complemented by the described insulation. This method is indispensable to protect the building from the deformation forces of frost heaving. The technology is particularly relevant on strongly heaving soils. Initially, it will be necessary to prepare a pillow on which the foam slab plates are laid, only after it is necessary to proceed to the formation of a concrete pavement.
Warming the basement penoplex do it yourselfcan be carried out according to the method of vertical insulation. This method is universal, as it can be used on a building under construction and on an already constructed building. In the latter case, it is necessary to dig out the base to the depth. Initially, the foundation is cleared of soil residues, various kinds of dirt and dust. If the surface has irregularities, it can be leveled using cement mortar.
The next stage is a coatingwaterproofing using bitumen or polymer mastic on a water basis. It is worth refusing from composition on the basis of solvents as penopleks from contact with them can collapse. You will need to buy glue for polystyrene foam, which is diluted according to the instructions. It should be well mixed and left to ripen. Next, the master proceeds to the layout of the foundation, on the surface of which the bottom line should be marked. If the structure has irregularities, the insulation may go deeper below the level of the sole, which, however, will not have a negative effect on the final effect.
If you decide to carry out basement weatherizationdo it yourself, then in the next step you need to apply glue to the insulation in several places. If there is a completely flat surface, the composition can be leveled evenly.
Further penoplex 50 mm thickness is pressed againstfoundation, and then leveled when necessary. The next element is fixed using the mounting groove. Sometimes it is required to install penoplex in several layers, while the components of the insulation system must be placed in a staggered order so that the second layer overlaps the previous seam. This will achieve a positive effect. The second layer is fixed on the same glue, but the technology is not different.
Quite often recently producedbasement insulation penoplex. The technology of these works should be studied by each master who intends to do these manipulations. In the underground part of the base, an additional fixation is not required when laying the penoplex, since it will be sufficiently tightly pressed against the soil when backfilling. In the area of the base, the penoplex is additionally fastened with special dowel-nails. They have a wide plastic cap that allows you to hold the material on the wall without rising above its surface.
Holes must be drilled through the slabs,which should go on concrete by 4 centimeters. After you can begin to install fasteners. The length of the drill should be chosen taking into account the thickness of the material. If you insulate the foundation with foam plastics, the technology of which is described in the article, then for decorative finishing of the basement, you can apply tiled glue or plaster to the surface, additionally reinforcing the layers with a grid.
If the building is installed on a slab orstrip foundation, can be used for work penoplex, whose thickness is 5-10 centimeters. Initially, it is necessary to mark the site under the foundation, and then remove the top layer of soil, deepening taking into account the construction project. When removing the ground, try to make the bottom as even as possible; for this, the last 30 centimeters should be removed manually. The prepared site is well rammed, and after that it is filled with sand, which also needs to be compacted.
Перед тем как утеплить фундамент плитного типа, it is necessary to perform temporary formwork, and then to prepare a concrete base. The next step will be to fill the solution with a thin layer, the formation is not required. As soon as the concrete base hardens, the foam panels are laid on it, the installation grooves in which do not form gaps. The polyethylene film is laid on the penoplex, the joints of which should be glued with adhesive tape. With it you will be able to create a layer of waterproofing, which will prevent the flow of concrete through the plates of insulation.
For this work you canuse penoplex 50 mm thickness, this will be enough for regions with not too harsh climates. After performing all the above work, formwork can be formed by laying the reinforcement and the bay slab foundation. As soon as the solution hardens, the formwork is removed, and the side walls are additionally insulated with the same material. If we are talking about a shallow ribbon foundation, then the work should be carried out using a similar technology.
If you pondered the question of howto warm the foundation, you can choose a technique that provides for the insulation of the soil. This not only reduces the estimated depth of the foundation, but also reduces construction costs. During the work it is necessary to equip the insulated blind area. As soon as the vertical external insulation has been completed, it is necessary to backfill with gravel and sand 15 centimeters below the ground level.
Далее следует приступать к формированию опалубки from boards with a distance from the wall a distance equal to a meter. The height of this design should be approximately 30 centimeters. Penoplex, which will be installed a little later, is purchased in advance. At the next stage, the bottom of the blind area must be tamped and leveled. Now you can proceed to the laying of insulation boards around the perimeter of the base. A polyethylene film is laid on the insulation with an overlap on the basement, after which you can pour concrete into the formwork. Its surface is leveled to form a slight bias on the outside. After hardening the mortar, the formwork can be removed, and the blind area should be ennobled with a decorative stone or paving slabs.
Penoplex, the cost of which is 1580 rubles.shipped in individual packages. For example, the consumer will have to pay the mentioned price for 5.76 square meters of material, which is 0.288 cubic meters, or 8 plates.
