A pressure-treated timber crib wall was selected to hold back 22 feet of earth. The box-like construction consists of treated wood members bolted together and filled with rock or other suitable material. The shear weight of a properly designed crib prevents it from turning over or sliding. It thus becomes part of the soil in which it is partially buried, acting as an effective, low-cost retaining wall. These walls are not limited to low embankments, they can be built relatively high. Part of the crib's low cost can be attributed to its lattice-like, open construction.
