Project Description:

Installed a retaining wall to reinforce stability and minimize soil erosion from the steep slope alongside the house.  Client was also concerned about water runoff from the slope so a drainage system was installed behind the wall to manage water disbursement.

  • Installed drain tiles below ground to allow for proper water disbursement
  • Placed heavy fabric at the base before retaining wall is built
  • Layered 2'-3' rock boulders to establish a 3-tiered wall (3 feet tall, 15-to-30 feet in length) to provide optimal erosion control and stability

Core Materials:

  • 2'-3' rock boulders
  • 4" non-perforated drain tiles

Project duration:
