These guys were really great, I had them come quote a job where they could have easily made a buck off of me, but instead they told me how I could easily do the project myself and save thousands. Feels rare to come across honesty like that! I would definitely trust this company to do an amazing job. I’ll be calling them for future needs!

It’s important for safety and legal reasons to have a properly constructed retaining wall where needed. The good news is, it’s pretty easy to determine when you need a retaining wall, outside of aesthetic reasons. This is one of the most commonly asked questions of homeowners who ask us about retaining walls in their backyard.

The maximum slope for the soil you can safely go without having a retaining wall is 35 degrees. This is especially important if the soil is granular. If the angle is steeper than 35 degrees, you need a retaining wall to keep the landscape in place. The lean should be minimum of 1:12 (1 inch per 12 inches of height) to ensure the load is evenly distributed to the wall. This will also allow for proper drainage of the soil.
