A gravity wall is a retaining wall that does not use soil reinforcement. A gravity wall has height limitations specific to each product. A gravity wall relies on the weight and setback of the block to resist the soil forces being exerted on the wall.
A geosynthetic-reinforced wall needs to be designed by a qualified engineer. With reinforced retaining walls there are (theoretically) no height limitations, and it is are used in larger applications. It requires more work area behind the structure. The block of soil is stabilized by introducing reinforcement layers into the soil mass behind the facing units. The larger the stabilized soil mass, the more soil can be retained or held back. The geosynthetic reinforcement in the soil extends past the theoretical failure plane and serves to create a large rectangular mass of block and soil, restraining the retained soil.
A retaining wall built with Anchor™ products and self-compacting structural backfill that meets Anchor Wall Systems, Inc.'s specifications, and that is backed by engineering support tools developed by Anchor Wall Systems.
An installation method that connects earth anchors to retaining wall blocks, that may be used where sufficient space for placement of geosynthetic reinforcement does not exist.
