TL;DR
Retaining wall geogrid is the polyester or polypropylene mesh reinforcement laid horizontally between block courses and extended back into the compacted fill, turning the soil mass itself into part of the wall's resisting structure. Design charts call for layers at set vertical intervals, with embedment lengths commonly 60 to 100 percent of wall height.
What it means
Retaining wall geogrid is the polyester or polypropylene mesh reinforcement laid horizontally between block courses and extended back into the compacted fill, turning the soil mass itself into part of the wall's resisting structure. Design charts call for layers at set vertical intervals, with embedment lengths commonly 60 to 100 percent of wall height. Most segmental walls taller than about 4 feet require it along with engineering, and omitting it is the usual autopsy finding on bulged or toppled walls.
