Holders of country houses are in great trouble cracks in the walls of the building, as well as the various distortions of the door and window frames, followed by jamming of windows and doors. Usually all these adversities begin in the autumn-winter period. This process is associated with the deformation of the foundation, due to the forces of frost heaving of the soil.
Foundation insulation: what is it for?
As the main measures to eliminate the forces of frost heaving can be considered the device base, located below the freezing mark. To accomplish such a foundation, very significant funds are required, and if there is little money, and the desire for construction is large enough, then the foundation must be insulated. At the same time, measures should be provided that are aimed at minimizing the impact of heaving forces.
Sometimes during the construction of buildings, the issue of heat loss in the cold is given only partial attention. And here the need to save heat in the foundation is often overlooked, while up to 30 percent of it is lost. If based on such statistics, then you can save heat at the stage of laying the foundation.
First of all, it is required to determine what materials will warm the foundation. It is traditional and most effective to use polystyrene, mineral wool and polystyrene foam. In addition to such materials, mineral fiberglass wool can also be used. All of the listed materials have various technological parameters. However, different climatic zones put forward different requirements for building materials. Therefore, the insulation of the foundation should be carried out by means of such a material that has an appropriate coefficient of density, heat conductivity and water absorption.
Usually a standard method is used, which implies complete insulation around the entire perimeter. Provides the most effective protection against the effects of frost. The main goals of such insulation are the restriction of the foundation from the influence of low temperatures, as well as the conservation of heat that has already accumulated inside. In addition, the warmed foundation made it possible to exclude the penetration of moisture and the accumulation of condensate. The material chosen for this is attached to the walls with glue based on a bitumen-cement composition. The joints between the insulation boards must be repaired using bitumen mastic. After that, a layer of soil is poured onto the insulation around the entire perimeter, which is then rammed.
Basement insulation foam
At the moment, this method is widely used in industrial and private construction. This type of material has truly excellent thermal insulation properties, it is completely safe for the environment and people. Among its practical advantages are ease of use and durability. Such insulation can be done without the use of special equipment and machinery. For this, a person must have minimal experience in the field of decorating.
Basement insulation polystyrene foam
Expanded polystyrene is usually produced and sold in the form of bulk mats or slabs. It is quite lightweight, while it has a high degree of thermal insulation, and financial costs are minimal. Work should begin with an audit of the state of the foundation of the structure. Expanded polystyrene plates will need to be attached using special glue, and the gaps should be sealed with a mounting foam, which is intended for outdoor use.
As you can see, warming the foundation is a fairly important event, which involves the use of different materials depending on the type of structure and the desired effect.
