What is a Retaining Wall
A retaining wall is generally defined as a vertical wall that holds back earth. However a retaining wall has many uses such as:
  • A retaining wall for roadside embankments
  • A retaining wall can separate older roads from highways
  • A house retaining wall for the garage
  • A retaining wall helps keep river banks from eroding
  • A retaining wall to keep earth from stairwells and driveways


Retaining Wall Construction
How to build a retaining wall depends on the type of retaining wall system you choose. During home retaining wall construction, you must choice between the different types of retaining wall construction methods. The most popular choice for retaining wall construction is concrete. Some retaining wall construction types are:
  • A concrete retaining wall
  • An interlocking block retaining wall
  • A Wood retaining wall
  • An Insulated Concrete Form retaining wall or ICF retaining wall
After the retaining wall construction is complete, the retaining wall is then backfilled on one side only. Backfilling on one side of the retaining wall creates an extreme amount of pressure. This pressure comes from the weight of the earth and the moisture in the soil. This pressure can result in cracks and water seepage in the retaining wall. During retaining wall construction you should always remember a proper drainage system. Installing a drainage membrane during retaining wall construction will help prevent the effects of water seepage. Some of those effects are:
  • Green slime
  • Efflorescence
  • Mineral deposits
  • Rust from wall tie
Freeze and thaw cycles also creates extra stress on a retaining wall. Expansive and soft soils can also account for some retaining wall problems. Installing a drainage membrane with drain tile on the backfilled side during retaining wall construction or during a repair of a retaining wall will help reduce or eliminate most of problems associated with a retaining wall.
