The main building material for the construction of the foundation of the building is concrete, the material is strong and resistant to various physical exertion and chemical destroyers. But as a heat insulator, concrete itself is a useless choice, it easily heats up and also easily gives the accumulated heat to the materials surrounding it. Therefore, the room behind the concrete wall, which is in contact with the frozen ground, will not be cozy and warm. The question of what to do in this situation, and the answer is unequivocal – the walls must be insulated, not to mention such an operation as a waterproofing device. Insulation can be arranged in several ways that differ among themselves, but the same in essence.
One of the methods of insulation is insulation when pouring a strip foundation in a non -removable formwork made of polyurethane plates, which are installed instead of wooden shields of removable formwork. The tape is poured with concrete and slabs – this is already thermal insulation. The already erected foundation is possible outside and from the inside, on top of the applied waterproofing that you can order at UTEPLENIE-Fundamenta. html, glue the same polyurethane foam plates. You can apply a layer of liquid polyurethane using a spray installation. In this method of applying, the insulation is obtained without cracks and seams, is tightly glued to concrete and is not afraid of moisture, not frost.
The traditional ways of insulation of foundations, can be backfilling cavities along the perimeter of concrete casting per width of 50 centimeters, expanded clay. It is expanded clay to pieces of baked clay, treated at very high temperatures in special rotating furnaces. They can also insulate the gender of the basement, use expanded clay as a filler for a concrete mixture. Another traditional material for insulation of foundations can be ordinary sand, and it is desirable to use it on heaving soils to eliminate the effects of soil movements. It is possible to apply several layers of mastic to the outer wall of the foundation, as a type of insulation, and then glue the waterproofing on top of the applied mastic.
