Uniaxial Geogrid

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.

Uniaxial Geogrid

A special type of geogrids made of high density polyethylene. In the manufacturing process, the perforated HDPE place is stretched in one direction, resulting in the final product’s rigidity and strength of 40 to 160 kN/m, depending on the geogrid type. Uniaxial geogrids are applied to reinforce scarps and embankments and repair of landslides and the construction of retaining walls.

Application

  • Reinforcement of scarps, repair of landslides

  • Anti-corrosion earthworks

  • Reinforcement and construction of embankment extensions

  • Construction of bridgeheads

  • Embankments of water reservoirs, dams and waste landfills
