Warming of the basement makes it possible to make the building much more comfortable to live in and significantly extend the period of its operation. Materials suitable for the insulation of the foundations of houses, there are many. But the most popular at the moment is Penoplex Foundation.

How to make

Like any other "Penoplex", this variety is made by mixing polystyrene pellets under high pressure and at high temperature. In this case, a special foaming agent is added to the mass, after which it is squeezed out of the extruder.

Material Advantages

The main advantages of the "Penoplex" boards, intended specifically for foundations, include:

  1. The minimum degree of water absorption.
  2. High strength.
  3. Resistance to decay.

Simply put, Penoplex Foundation is superior to other varieties of the same brand material, primarily in terms of strength and biological stability. Also, its advantages include the fact that it completely lacks cold bridges. The plates, intended for warming the foundations, are connected according to the principle of the spike-groove. That is, when using them, there is no need to seal joints with mounting foam or sealants having a higher degree of thermal conductivity.

How to choose a material

The thickness of the sheets of "Penoplex" of this variety can be very different (from 20 to 100 mm). The choice of material for this indicator depends primarily on the climatic conditions of the region in which the house is built. In the central strip of Russia the recommended thickness of foamed insulation for foundations is 100 mm. Therefore, it is the "Penoplex Foundation" 100 mm that is suitable in this case most of all.

A very good solution will also be to buy 50 mm slabs and lay them in two layers. In this case, the appearance of cold bridges can be completely ruled out. For this, the 50 mm plates of the second layer are mounted on the sheets of the first with an overlap, completely overlapping the joints in this way.

Cost of material

Mounting technology

The base of the house is warmed with the material "Penoplex Foundation" as follows:

On the perimeter of the building, a trench 1.5 m wide (up to a sand pillow) is excavated.

Drainage is arranged for drainage of soil moisture. For this, gravel and sand are poured onto the bottom of the pit. Further geotextiles and drainage pipe are laid. Then the pipe is poured with rubble. After that, the edges of the geotextile are wrapped upward. Above lay another layer of crushed stone.

The foundation itself is being prepared. Its surface is cleaned of dust and, if necessary, leveled.

Apply a layer of waterproofing. In order to protect the foundation from moisture, it should be smeared with bitumen or polymer mastic in two layers.

Plates are fixed on the surface of the Foundation of the house with a special adhesive. If used for insulation "PENOPLEX Foundation" of 50 mm, the second layer is placed so as to cover the joints.

On the plinth base plates are additionally fixed with dowels-fungi.

At the final stage, the surface of the plates is plastered.

The pit falls asleep after the upper protective layer has completely dried and seizes.

Construction of the blind area

So, "Penoplex Foundation" is installed. What next? And further along the perimeter should be poured blind. This will extend the life of the insulation to the maximum. The blind is poured in the following way:

On the perimeter of the house dig a trench 20-25 cm deep.

It is poured into 15 cm of sand.

Further along the entire length of the trench lay a roll-up waterproofing.

Sand is poured onto it again.

Above to the ground level, rubble is laid.

On the perimeter of the house set a low formwork from the board (10 cm).

Fill in about 7 cm of concrete.

Without letting him grab, lay the reinforcing mesh.

Fill the formwork with concrete up to the top with the device of expansion joints with a step of 2.5 m.

Create the desired slope of the blind area.

Produce iron in concrete.

As you can see, the insulation "Penoplex Foundation", the price of which is not particularly high, is remarkable for its performance characteristics, and it is not difficult to mount it. For use as a protection of the base of the building, it fits just perfectly. Therefore, it is definitely worth it to buy it for gluing the foundation of your house.
