High Strength PP Warp Knitted Geogrid

High Strength PP Warp Knitted Geogrid known as PP Grid is woven by high strength polyprolene yarns as per desired mesh sizes and strength from 20kN/m to 800kN/m(Biaxial type), 40-25kN/m to 600-400kN/m(Uniaxial type). Woven PP Grid is created through interlacing, usually at right angles, two or more yarns or filaments. Exterior of PP Grid is coated with polymer or nontoxic substance material for UV, acid and alkali resistance and prevents the bio-decomposition.

Description

High Strength PP Warp Knitted Geogrid Features:

  • High intension,high tenacity,high occlusive force with soil or gravel,erosion-resistant,water drainage,light weigth.
  • Reinforce soft soil roadbed,rib side slope of embankment,enhance isolation,inhibit ground deformation,prevent crack by reflection,increase strength of roadbed.

Application:

  • Roadbed reinforcement of road and railway,crack prevention,increase of roadbed strength;
  • Reinforcement and stabilization of riverside,embankment and side slope;
  • Dyke reinforcement on soft ground for stress evenness,sedimentation adjustment,increase of stability and loading capacity of fundus;
  • Reinforcement of the surface of road and bridge.
