There are many landscape contractors who can construct a wall. A common misbelief of many homeowners is that the retaining wall block itself supports the wall. The block surprisingly does little to hold back the earth behind it. To build retaining walls, the installer must understand soil types and water drainage behind the wall they are building.

Without proper drainage, water pressure from storms will build up behind the wall and eventually push the wall over. Many concrete retaining block systems have tabs, pins or tongues and groove concrete molded into the block- but these are tools for the installer to help keep the wall straight during construction. Redirecting storm water flow is the highest priority in building a wall that will last.
