Concrete retaining walls provide lateral support for backfills. (A backfill is a vertical slope of earth held back from an adjacent level plain.) These structures offer some very important benefits to homeowners investing in residential landscape design. On a functional level, they ensure that the constantly shifting and crumbling claylike soil of Houston is stabilized as much as possible with advanced surface leveling and drainage techniques. This is particularly true for Houston homeowners who live anywhere near Buffalo Bayou or one of its tributaries. Backyards in these neighborhoods often slope toward the banks of the stream.
A concrete retaining wall, and corresponding drainage system, provides not only a more level yard for landscape design, but also functions as an erosion control system.
