Principles of polystyrene insulation technology foundation

Principles of polystyrene insulation technology foundation

technology polystyrene thermal insulation foundation involves the creation of a reliable thermal insulation protecting the house foundation.

As you know, one of the main elements of any structure, from which depends the safety of the operation of the house, it is a foundation.

That he had longevity and gave maximum stability throughout the house, it is necessary not only to properly design, but also to build.

also recommended to conduct additional insulation on the outside of the foundation, which will increase the quality and durability of buildings, energy-saving features of the internal space.

In this case, the optimal insulator is a polystyrene plate, which, compared with other similar materials, have a large number of advantages, and in addition, since they simply operate.

Styrofoam can be used for melkozaglublennogo tape or pile foundations, as well as for the base screw design.

To be most effective insulation of expanded polystyrene foundation is best done outside, the thickness of

the insulation layer is selected based on the external climatic conditions and soil characteristics.

Benefits of using Styrofoam

Currently, during the insulation of any surfaces outsideis used polystyrene plates and it is connected primarily with the fact that this material, in addition to the huge number of advantages, is still relatively low cost.

Its active use, including, if necessary, and perform insulation melkozaglublennogo pile, ribbon and other types of foundations, as well as the blind area.Today

can acquire two different types of expanded polystyrene, namely, the extruded and foamed.

Between them there are some differences, both in technology and specifications.

For warming melkozaglublennogo belt, piling and other types of foundations is best to use extruded, as it is more resistant to various external influences.

Of course, the main advantage of EPS boards is their relatively low price, which is an order of magnitude lower than that of similar materials.

Also, polystyrene plates are compact.Their thickness can vary, ranging from one centimeter and ending ten.

Also, polystyrene plates are lightweight, which greatly simplifies the process of laying the material.

polystyrene plates have good resistance to all kinds of aggressive factors, including chemicals.

Insulation for foundation

material has a low absorption of moisture, high performance density and reliability, which increases its durability.

addition, polystyrene is absolutely harmless to health, as it has a high environmental performance.

Due to its versatility, polystyrene can be used for insulation melkozaglublennogo belt, piling and other types of foundations, as well as for the blind area.


Before you proceed with the work on the expanded polystyrene insulation sheets of the foundation, including the outside of the belt type, it is necessary to prepare the tools, as well as purchase the material itself, the thickness of which is determined on the basis of external conditions.

for insulation is best to use extruded polystyrene foam.Particular attention should be paid to the choice of adhesive, which will be planted in the course of work directly plates themselves.

is followed around the perimeter of the dig around at full depth the very foundation.Also, all its base it is imperative to thoroughly clean the residue from the ground, as well as dirt and dust.

trench base

Experts recommend to bring the same level for its entire surface.

In addition, before starting work related to the installation of EPS boards should be thoroughly dry the entire surface of the foundation grounds outside.

thickness of the plates that will be used for insulation of the foundation shall be not less than ten centimeters.

After the concrete base of the foundation is dry thoroughly, it is mandatory to carry out waterproofing work.

This is especially true for the foundations of the buildings, which are located in the immediate vicinity of the underground water table.

For these purposes, you can use very different materials, including lubricative.In

if accepted to use as a waterproofing obmazochnye foundation compositions, it is necessary to stop the selection of mastics which are water-based or polymer.

also recommended that you drain the entire space near the base, which can later be using to hide the blind area.

To do this, at the bottom of the trench densely compacted layer of sand and gravel, which is laid on top of a perforated pipe, which is also sprinkled with gravel and sand.

Note that basement waterproofing is an important milestone, and therefore it must be approached with full responsibility.

For more information on how to properly insulate the foundation, told in the video below.


Installation of sheet insulation

polystyrene plates are mounted on the foundation of the house from the outside using special adhesives.

It is undesirable to use for this purpose are mixtures which in its composition contain different types of organic solvents.

adhesive is applied directly to the insulation itself single point, after which the plate is pressed tight to the ground and fixed at a certain time.

is best foundation insulation polystyrene perform stripes, starting from any corner of the lower base.

next upper layer of insulation is required to fit in a checkerboard pattern, in order to avoid bad connections seams.

Laying insulation

After the installation of the insulation will be performed on the entire surface of the base of the house, all joints and gaps between the plates must be as carefully sealed.

For these purposes, you can take advantage of the mounting foam and adhesive may be used alone.

In order to carry out the work it was more convenient, it is recommended after laying the first layer of insulation and sealing, make a partial backfilling of the pit.

Practice shows that the weakest point of any foundation are its corners.When the foundation of the house insulation corners should be given special attention.

So, it is recommended to lay the insulation in multiple layers, with maximum seal every seam.

After you have made all the base insulation around the perimeter of the house, you must make an even filling the trench with a mixture of soil and sand, and then thoroughly compacted.

also recommended to carry out insulation and the entire basement of the house.This will further strengthen the foundation, and accordingly, to increase the durability and the house.

For more information about how to perform insulation polystyrene foam base at home, described in the video, which is available below.


Tips and tricks

entire heater is recommended on top of plaster adhesive, which is designed to perform the finishing work.

In addition, to enhance the protective functions of the foundation should make additional insulation blind area around the perimeter of the house.

as insulation for the blind area can use a variety of materials, including polystyrene foam.

selected heater fit after the drainage will develop a blind area and a pillow, and laid insulation.

Laying insulation

Top heater settling concrete screed, also allows stacking on top of it paving slabs.Warming of the blind area will increase the reliability of the foundation, but other than that will prevent the ingress of moisture and dampness.

In that case, if a house built on the ground with a large depth of freezing, we recommend that further protect the insulation from mechanical damage of different nature.

most optimal way to build such a defense - it is run on top of the Styrofoam brickwork.

If all work on warming the foundation carried out correctly and in accordance with standard technology, the foundation of the house is well protected from cold and moisture.Perform

insulation is recommended for all types of substrates, regardless of whether it is erected on any terrain.
