Geogrid Installation

What happens here

After a course of blocks is laid, a layer of geogrid is rolled out over the blocks and extended backward into the area that will be backfilled. The geogrid acts as a soil reinforcement, providing tensile strength to the soil mass behind the wall, effectively creating a larger, stronger composite structure. The blocks of the next course are placed directly on top of the geogrid, anchoring it in place. The length and number of geogrid layers depend on the wall height, soil conditions, and design specifications. Although not explicitly detailed in the video, proper geogrid installation involves tensioning the grid and ensuring continuous coverage as layers of backfill are added and compacted.

Goal: Geogrid is strategically placed between courses of blocks and extended into the backfill to reinforce the soil and enhance the wall's structural integrity, particularly for taller walls or those under significant pressure.
