TL;DR
Geogrid reinforcement is a polymer mesh layered into compacted base or retaining-wall backfill to lock aggregate together and spread loads laterally. Segmental retaining walls over about 3 to 4 feet typically need it, with layers extending back into the soil at intervals set by the wall engineer or manufacturer tables.
What it means
Geogrid reinforcement is a polymer mesh layered into compacted base or retaining-wall backfill to lock aggregate together and spread loads laterally. Segmental retaining walls over about 3 to 4 feet typically need it, with layers extending back into the soil at intervals set by the wall engineer or manufacturer tables. On paver driveways it stiffens the base over weak subgrades. A bid should state the grid strength, number of layers, and embedment length, since those govern whether a tall wall stays plumb.
