Warming the foundation allows you to make the building much more comfortable for living and significantly extend its life. There are many materials suitable for insulation of the bases of houses. But the most popular at the moment is Penoplex Foundation.
How to make
Like any other "Penoplex", this variety is made by mixing polystyrene granules under high pressure and at high temperature. In this case, a special foaming reagent is added to the mass, after which it is squeezed out of the extruder to the outside.
The main advantages of “Penoplex” slabs intended specifically for foundations include:
- The minimum degree of water absorption.
- High strength.
- Resistance to decay.
Simply put, Penoplex Foundation surpasses other varieties of the material of the same brand primarily in terms of strength and biological resistance. Also, its advantages include the fact that there are no cold bridges in it. The plates intended for warming of the bases, by the principle a thorn groove connect. 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 “Penoplex” sheets 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 central Russia, the recommended thickness of foamed insulation for foundations is 100 mm. Consequently, it is “Penoplex Foundation” 100 mm that is most suitable in this case.
A very good solution would also be to purchase 50 mm plates and lay them in two layers. In this case, the appearance of cold bridges can be completely eliminated. For this slab, 50 mm of the second layer is mounted on sheets of the first with an overlap, thus completely overlapping the joints.
Cost of material
The base of the house is being insulated with Penoplex Foundation material as follows:
A trench 1.5 m wide is dug along the perimeter of the building (up to the sand pillow).
For drainage of soil moisture is arranged drainage. To do this, rubble and sand are poured at the bottom of the pit. Next fit the geotextiles and drainage pipe. Then the pipe is covered with rubble. After that, the edges of geotextiles are wrapped up. Top lay another layer of rubble.
The foundation itself is being prepared. Its surface is cleaned from dust and leveled if necessary.
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 base of the house with a special glue. If for insulation “Penoplex Foundation” 50 mm is used, the second layer is placed in such a way as to overlap the joints.
On the base plate, the plates are additionally fixed with fungi dowels.
At the final stage, the surface of the plates is plastered.
The pit falls asleep after the top protective layer is completely dry and grabs.
Construction of a blind area
So, “Penoplex Foundation” is installed. What next? And further along the perimeter one should fill the blind area. This will extend the service life of insulation to the maximum. The blind area is flooded as follows:
At the perimeter of the house they dig a trench 20-25 cm deep.
15 cm of sand are poured into it.
Further along the entire length of the trench lay rolled waterproofing.
Sand is poured over it again.
From above to the ground level stack rubble.
Along the perimeter of the house install low formwork from the board (10 cm).
Pour inside about 7 cm of concrete.
Without letting him grab, lay the reinforcing mesh.
Fill the formwork with concrete to the top with the device of expansion joints with a step of 2.5 m.
Create the desired slope of the blind area.
Concrete is ironized.
As you can see, the insulation “Penoplex Foundation”, the price of which is not particularly high, its performance characteristics are simply remarkable, and it is completely easy to assemble it. For use as a base protection for a building, it fits just perfectly. Therefore, it is definitely worth buying it for pasting the foundation of your house.
