How to insulate the foundation of the house

To make a private house cozy and warmer in winter cold, sheathing walls, roof, do not forget about the foundation. This is especially true of those who live in a terrain with a harsh climate, or the soil on which the house stands is freezing to a greater depth. Such bubbly soils are able to increase in volume when freezing, loosening the foundation and forming cracks. Consider the most effective ways of insulation of the foundation.

Warming planning should be started from the selection of heat-insulating material. The basic requirements for them: do not have to deform under the severity of the soil, absorb moisture. Widely used mineral wool for such a type of work does not suit its fragility. There are more durable materials, with high thermal insulation qualities.

A fairly efficient and cheap way - insulation with clay. With it, you can warm the foundation before and after the fill. Ceramzite falls asleep inside the formwork, while both part of the wall and the floor are insulated at the same time. Ceramzite is a porous material, so it does not miss the cold, moisture and maintains heat. It is used for shallow foundations. Digging on the entire perimeter of the house with a width of 1 m. The walls of the foundation are purified from the ground and make waterproofing using a rubberoid. It is covered with a thick layer of grainzit granules, then laid a layer of rubberoid and fall asleep all the earth. Advantages: Small price, environmental friendliness, strength, resistance to ignition. Disadvantages: the complexity of the process of insulation, when the cement gets through the granules, heat may occur, in wet areas, measures are needed on the removal of water.

Modern material polyurethaneretan may be used for hydro, sound and thermal insulation. The main advantage of this method is the absence of seams through which the cold can penetrate. His layers are sprayed with special equipment. During the application, polyurethane foam is in a liquid state and envelops the entire surface, filling the slots, microcracks. This technology can be used when erecting a building or during operation. There are companies providing services for insulation of polyurethane foam. Benefits of this material: seamlessness, reliability, low vapor permeability and heat permeability, long service life, does not require additional insulation by rubberoid. Disadvantages: Special equipment is necessary, partially collapsed under the influence of UV rays.

Extruded polystyrene foam also completely eliminates heat loss. It is sold by plates that have a cellular-closed structure. Polystyrene foam does not absorb and does not pass water, therefore it does not destroy at low temperatures. This material is characterized by stable maintaining thermal insulation characteristics and a long service life. Useful service time - 50 years. Advantages of polystyrene foam plates: Strength, low price, light share, hygroscopicity. Disadvantages: susceptible to fire, small sound insulation properties.

For insulation, the soil is cleaned around the perimeter of the foundation, clean the walls from the ground and ground primer. After drying, the primer is carried out waterproofing with liquid rubber or rubberoid. Over the waterproofing layer, polystyrene foam plates are fastened with bitumenopolymer mastic or polyurethane glue. The tool is damaged or over the entire surface of the slab. Plotches are also missing with adhesive composition. The extrusion plates "Penoplaks", "styrene" have proven itself well.

The insulation of the foundation is not easy job, but performing the task. In order not to make extra costs, first make the surface area, the number and cost of building materials.
