Retaining Wall Held Together with GeoGridGeoGrid is used for reinforcement in the construction of concrete modular block retaining walls.  It is composed of high molecular weight, high tenacity multi-filament polyester yarns that are woven into a stable grid network and placed under tension.  It comes in different tensile strengths, roll widths, and lengths.   Acting as a ‘dead man’ did in the age of railroad tie walls, geogrid is installed at various standard heights in a block retaining wall.

There are engineered specifications for applications and heights of walls for the St.Louis and Jefferson County, MO areas. Under normal circumstances, any wall over 3′-6″ should have geogrid installed unless specific arrangements are made with a local structural engineer.  Without the proper use of geogrid a retaining wall can fail, leaving the homeowner or business owner with a huge headache.  A wall can not be straightened once it leans out without taking down the wall and rebuilding it piece by piece.  Do yourself a favor and make sure GeoGrid is installed in your new retaining wall!
