Retaining wall structure for soil stabilization including double layer of geogrid web material to provide high strength connection with backfill material
A retaining wall connection for mechanically stabilized earth structures comprising a plurality of courses of cementations blocks stacked together to define a retaining wall and having a backfill material provided behind the retaining wall. A first layer of geogrid web material has a leading edge disposed between vertically adjacent blocks at a predetermined vertical height of the retaining wall with the trailing edge of the first layer of geogrid web material extending backwardly into the backfill material so as to be engaged thereby. A second layer of geogrid web material is provided so as to overlay and contact the first layer of geogrid web material from the leading edge thereof to at least a medial portion of the first layer of geogrid web material in order to provide a significant increase in the connection strength in the retaining wall and the backfill material. A method for forming a retaining wall structure for mechanically stabilized earth is also described.
