The open core design of the Keystone’s Compac retaining wall unit ensures sufficient fill placement. It reduces overall unit weight, and enhances connection strength with geosynthetics. Fiberglass pins connect and align the system, to provide a secure connection with soil reinforcement materials.
From large, load-bearing reinforced structures to residential landscapes, the height-to-depth ratio delivers walls with good erosion control, stability and strength. In addition to the traditional straight-face or tri-plane styles, Sculpterra Technology can be used on Compac units to create alternate face options. Keystone Circle 520 on Reader Response Card

The most commonly used fabric for erosion control in residential and commercial construction is now being sold by the DeWitt Company. Made of woven polypropylene yarns, their design is meant to block sediment from flowing out into streams and rivers while letting water pass through to accumulate elsewhere. This device can not only prevent soil from washing away, but ensures that it doesn’t end up harming any aquatic life.
