A geogrid is a geosynthetic with large openings or apertures.
Plastic Geogrids are used as soil reinforcement below roads, under structures and behind retaining walls.
Biaxial Geogrid also reinforce paving overlays. Geogrids can be uniaxial (strength in one direction) or biaxial (equal strength in both directions) and are made from polyester, polypropylene or fiberglass.
Manufacturing methods include woven, knitted, extruded or otherwise "integrally formed”.
2. Product Application:
Soft foundation reinforcing for highway, railway, Slop protecting projects, landfill side
Function:
Improve the bearing capacity of foundation;
Preventing cracking and subsiding;
Convenient to construct, reducing cost and maintaining expense
