Geogrids PG-Poliset are polymer grids consisting of two systems of polymer yarns knit together by a third knitting polymer yarn. Impregnation is done with binding substances on the basis of polyvinylchlorides. These geogrids are used as a reinforcing (separation) interlayer under the bearing course of the subbase of road pavement made of a granular material (crushed rock or gravel). Application of a reinforcing (separation) interlayer allows to prolong the life of the construction, to increase its shear resistance and serviceability, to reduce the thickness of the layers, to prevent rutting, to significantly decrease penetration of the granular material of the subbase into the underlying dirt layer, both during building and during operation.

The three-dimensional structure of a geomat prevents vegetable soil creep along a slope and fixes the roots of plants growing out, which is the most important during formation of root systems.

Composite mats TDCGM are mats TDM having an additional structural element – geogrid made of polymer yarns and rovings. Mats of the TDCGM type are intended for use as a reinforcing element on high slopes subject to soil slip.

Three-dimensional mats of the TDDGM type are intended for reinforcement of drainage constructions and waterways. They may be used in building of industrial and domestic waste disposal sites being the lower layer as drainage and in constructions of safety screens on the surface.

Reinforced plastics are composites on the basis of a polymer binding substance (matrix) and a reinforcing filler of a fibre pattern. Heat-convertible resins and engineering thermoplastics are used as binding substances. Inorganic and organic fibre materials in the form of monofilament yarns, complex yarns, short (discontinuous) fibres, tows, fabrics, felts and single crystal filaments serve as fillers.
