POLISET geogrids

POLISET geogrid is a polymer grid formed by two systems of polymer yarns interknit with a third one, a knitting yarn, and impregnated with a polymer binding agent.

Typical application:

polyester-based geogrids are used to ensure stability, steadiness and required load-carrying capability of road structures, аs well as to prevent ingress of coarse-fractioned materials to underlayers when constructing permanent and temporary roads, including those on weak base.
- the grids are manufactured of high-strength corrosion-resistant polyester yarns,
- sucsessfully used for reinforcement of road dressing in touch with coarse-fractioned (inert) materials.
