HDPE/PP Uniaxial Geogrid
HDPE/PP U Geogrid are made from high molecular polypropylene or high density polyethylene polymer through extrusion, forming and punching before longitudinal stretching.
This material has considerable tensile strength in longitudinal directions.
This chain structure can effectively bear and diffuse forces on soil and is applicable to large area permanent load bearing foundation.
