Retaining Wall Design
The project included designing a 16-foot tall retaining wall along the rear of the lot to create yard space behind the house under construction. Due to space constraints from the location of the house to the rear property line, Shield designed an interlocking double-faced gravity segmental retaining wall that did not include geogrid reinforcement. Shear pins and epoxy were utilized to give the wall an 8.8-degree batter, and the wall was constructed at a 10-degree batter to provide a total angle of 18.8-degrees from horizontal.
Shield’s design met the clients request that the segmental retaining wall be constructed from the same type of those on neighboring properties without infringing past the property line, and allowed for an increase in the amount of yard space. Further, the 18.8-degree angle of wall construction created the impression of additional space.
