Insulation of the foundation with his own hands

insulation foundation - an important stage of warming the house.There are several ways to produce insulation of the foundation with his own hands.From the chosen technology will depend on complexity and cost of work material, and the quality of the insulation.

basement insulation methods

Technologies that insulate the foundation and insulate the building against cold from the ground, can be divided into two groups:

• Insulation of the outside of the foundation;
• Warming inside the basement.

The most effective insulation from the outside, and to begin its implementation on the best stage of construction of the foundation.When it comes to insulation of the basement or ground floor of the building is already standing, the outer insulation can be done only after the preparatory work for the cleaning and drying of the foundation.

Insulation of the foundation from the inside is also used in some cases, for example, when access to the basement from the outside is limited.Warming can increase the temperature inside in the basement, but it does not protect the base from the harmful effects of moisture and extreme temperatures.

basement insulation methods outside

Technology External insulation of the foundation at the moment there are so many, but they all boil down to four basic stages:

• Preparation and Purification of the foundation;
• waterproofing;
• Warming;
• Finish.

Warming foundation

backfill method is performed using the expanded clay, gravel and sand is poured into the trench dug along the foundation.Due to the good water diversion from the foundation base does not allow its destruction.

performance technology:

1. along the basement dig a trench width of at least 80 cm to its full depth, then clean the foundation wall of dirt, sand, dust.Dried foundation.
2. Perform waterproofing Okleechnaya or lubricative way.To wash use bitumen mastic.Back-lining method involves the use of tar paper or other film coating, bonded to a suitable composition.
3. filled trench is filled: at the bottom - a layer of sand of about 20 cm, the ram, and then pour concrete block building or gravel.Align the level of the soil or just above.
4. Perform blind area, following the slope of the walls, as well as finishing the basement walls that are above the soil level.

Warming foundation foam plates

done using panels of expanded polystyrene (styrofoam) attached to the foundation by means of an adhesive or mastic.Thermal insulation properties of the insulation, thanks to the foam's ability to hold the heat high.In the foam has a serious drawback - it is often damaging rodents.Therefore, on top of the insulation layer is necessary to fix the mesh-netting.

performance technology:

1. finished basement: dig, clean and dry.
2. Treat foundation primer for concrete with anti-bacterial components after drying waterproofing method of coating.
3. fastened to the foundation lath pine plank, processed biosecurity for foundations and structures in contact with soil.set foam sheets between them.
4. foam is fixed by means of special anchors in the form of the fungus, or zapenivayut shpaklyuyut all the gaps and over the entire structure to protect the grid.The mesh is attached to the crate.
5. layer of foam under the net with the help of plaster cement-sand mortar.
6. After drying, the solution is filled trench river sand.The protruding part of the foundation veneer, perform blind area.

Instead foam recently often used penoplex - modern and more durable material, resistant to deformation and damage by rodents.It can be glued directly on the foundation, on the layer of bitumen mastic or adhesive.

Thermal insulation with polyurethane foam foundation

modern and very effective way, but it requires special equipment and is expensive.But the quality of the insulation is incomparable with any other method - polyurethane foam has excellent adhesion and is not only a heater but also waterproofing.

performance technology:

1. surface is ready for insulation: clean, dry, remove dust.Work should be done in the warm season, because at temperatures below plus 10 degrees adhesion of polyurethane foam to the surface of the foundation deteriorates.
2. polyurethane foam is sprayed onto the surface of a thin layer, after which it is several times increases in volume.Forming a durable, sealed, environmentally friendly warming layer without thermal bridges.
3. After stabilizing the foam is carried out reinforcement, plastering, backfilling the trench and facing other works.

Warming foundation inside

Perform internal insulation of the foundation, you can use polyurethane foam layer deposition, as well as with the help of foam, mineral wool or any other heater.

performance technology:

1. foundation walls dried, if the basement is very wet - you can use for this purpose heat gun.
2. surface is clean from dirt, dust, residues and hydro insulation.Soil bacterial composition for brick and concrete.
3. Execute surface waterproofing using compositions based on bitumen.
4. If used as insulation mineral wool or foam plates, then prepare a framework of bars.It is also waterproofing.
5. Lay thermal insulation in a grid frame or sprayed polyurethane foam.
6. When using pervious insulation on top of it put a layer of vapor barrier membrane for removing water vapor.
7. Krepjat reinforcing mesh, plaster, and then the finish.

Performing insulation in any of the following ways to improve the microclimate in the home and extend the life of the foundation.Insulate the foundation must be around the perimeter of the building: insulation of individual sections may lead to its premature failure due to different operating conditions.
