Biaxial geogrids

Geogrids

The Pietrucha Group is the manufacturer of the PolGrid geogrids, specialized geosynthetics widely used in the civil engineering projects to stabilize and reinforce land or to separate the substrate layers with varying graining. The solid, integral structure of PolGrid products and four-sided openings function considerably better with  aggregate than flat profile grids or geogrids with rounded openings. Geogrids are used  in transport construction projects and other geothechnical works. PolGrid products are quick and easy to install and allow for the reduction of the use of materials, thus saving investment costs and saving time.

Biaxial geogrids

Geogrids with a rectangular cross-section of the rib. In the manufacturing process, the perforated PP plate is stretched biaxially. Owing to solid construction without any interconnecting junctions, biaxial geogrids are extremely durable and resistant to stretching. Stiff nods of the grid are an integral part of the construction and rectangular openings give excellent support to the aggregate.
