5 Factors to Consider for Retaining Walls

Retaining walls can add support, beauty and function to your landscaping, making them a popular hardscaping project. However, this is a project that needs some planning and preparation before you jump in. Before you head to the landscaping supply store for materials, here are some factors to consider for your new retaining wall.

  1. Weight. If your retaining will be used for functional support for a slope or hill, you need to determine the weight and pressure that will be against the wall.
  2. Foundation. All retaining walls need a solid, level foundation for the best results. A leveled area with compacted sub-base or gravel should be used in the foundation, with stable, heavy materials used at the bottom of the wall.
  3. Materials. Retaining walls can be made from wood, concrete or dry-laid stone. Natural stone or pavers are the most popular, offering strength, durability and beauty for the project.
  4. Drainage. Many retaining walls fail due to water pressure caused from inefficient drainage. Gravel fill in the foundation or piping to allow water behind the wall to drain can prevent drainage failure issues down the road for your retaining wall.
  5. Slope of wall. If building a retaining wall for soil or erosion support, sloping the wall back into the hillside can garner better results, referred to as a batter or cant.

Creating a plan for your retaining wall can reduce the chance of premature failure. Decide the dimensions, materials and design before you make your trip to the landscape supplier in your area. This will save you time and ensure you get everything you need for supplies before you begin building your new retaining wall.
