Earth reinforced with steel strips and faced with precast concrete panels has been used worldwide to build retaining walls, sea and river walls, bridge abutments, industrial facilities and earth-sheltered homes. Soil that is reinforced using this patented system acts as a single gravity mass, which can be engineered to withstand significant seismic, dynamic and hydrostatic forces. Static friction between the soil and the steel strips placed in the soil keeps the soil from sliding under lateral pressure. The result: a man-made earth formation that is actually an earth structure.


The steel strips are bolted to precast concrete facing panels which keep the soil from eroding. Construction is a repetitive process: precast panels are set in place one row at a time, reinforcing strips are attached, and backfill is spread and compacted over the strips.
