Abstract
A modular retaining watt has tiers of headers which extend into compacted backfill material and tiers of stretchers which extend between headers to form the front face of the wall. Vertical pins, extending between successive headers in each stack of headers, facilitate precise emplacement of headers during construction of the wall. Layers of geosynthetic mesh reinforcement reinforce the load bearing capability of the backfill. Load forces in the backfill are sustained by forward ends of the layers of geosynthetic mesh reinforcement, which extend upward in front of the backfill and then backward into the backfill, instead of being sustained by the stretchers. A sizable space behind the stretchers may be filled with loose topsoil to facilitate growth of landscaping plantings on the face of the wall.
