Who knows how much the staggered distance of the lap joint of the geogrid is?
A grille is made of polypropylene, PVC polymer and thermoplastic or molded by two-dimensional grid or a certain height of the three-dimensional mesh screen, when used as a civil engineering, called geogrid.
Straight and smooth and close to the cushion, all longitudinal or transverse lap joints should be staggered, overlapping length shall not be less than 300MM.
When the geotextile is used as the anti filter layer, it should be laid on the bottom and the sides of the trench wall, and the top cover of the geotextile is reserved,
The staggered distance of the lap joint shall not be less than 300 mm. Specific specification (geotextile lap laying)
