The increase of the energy resource prices has brought to the agenda the issue of heat insulation of buildings, which creates the necessity of production of high quality and at the same time inexpensive light heat insulation materials. For this purpose we must note the possibility of usage of the landslide deposits clay-shale of the Duruji River, which material has the capacity of self-loosening in the conditions of certain temperature mode. It must be noted, that as a result of annual landslide of the Duruji River 500 thousand tons of clay-shale is brought down, which creates the threat of ecological disaster for the adjacent areas, particularly Kvareli City. Therefore, on the one hand, usage of the clay-shale will support solution of this problem and on the other hand, we will have cheap mineral base for production of new heat insulation materials, the cost price of which is much lower than the selling price.

In the conditions of laboratory we have produced homogenous structure material, operating parameters of which are as follows: bulk weight – 300-650kg/m3, stability limit at compression – 0,6-2,5mgpa, water uptake – 3,5-7%, porosity – 60-80%. A plant producing light heat insulation small blocks can be constructed in Kvareli Region, close to the mineral base. And the waste of the block production can be used as porous filler, for both, production of light concrete and filling the inserted floors. Production will be non-waste. The main consumers of the product will be construction companies of Georgia and the Caucasus.
