The South Carolina Department of Transportation (SCDOT) needed to provide a right-of-way for an access road adjacent to a CSX railroad line.

Strata’s geotechnical experts suggested the StrataSlope™ system with two primary elements: StrataGrid™ 200 geogrid, a perfectly matched solid reinforcement, and a slope facing system. The geotextile provided temporary erosion protection until the concrete slope protection was placed. Outside the limits of the bridge, sod backed with a permanent erosion blanket, and the secondary reinforcement was placed adjacent to the welded-wire form. This facilitated immediate vegetation of the slope during construction and provided long-term surficial slope stability and erosion protection.

Strata’s innovative solution provided a structurally and economically sound solution, satisfying the structural requirements for the steepened soil slope, which was one of the client’s main requirements and the bent, welded-wire form facing system accommodated both the concrete slope protection and vegetation.
