Signs you should invest in retaining wall excavation

At RCJ Excavations, we do more than dig — we can help build, too, at least in terms of retaining walls. Our skills in this area are as extensive as our knowledge of the stable of earthmoving equipment we maintain. When is it a good idea to invest the funds to create a new retaining wall? 

Here are a few of the signs that say the time is right:

  • You have old existing retaining walls that have begun to fail due to material deterioration or changing soil conditions. Retaining installations that sag or otherwise have clear defects aren't safe and should be replaced. We can help with removing the old material and replacement with new solutions, such as cut sandstone.
  • You want to create a new outdoor or garden space, and the design you've produced uses retaining walls to separate and define the space. We're well-versed in setting up properties for these solutions.
  • You need tight access excavation assistance to dig trenches and place walls in small garden spaces that can't accommodate larger and heavier machines. A proven contractor will make this effort much easier to complete.
