Experts In the Design & Build of San Diego Homes & Landscapes

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 to keep in mind if the soil is granular. If the slope of your angle is steeper than 35 degrees, you will 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 recommendation will also allow for proper drainage of the soil. Wet soil and water buildup against any structure can be very detrimental, not only because it is heavier, but also erodes many compounds. Proper irrigation and drainage for your retaining wall and sloped yard is a necessary, and should be taken seriously. When landscape walls collapse, it can be bother dangerous and costly.
