Structural & Slope Retaining Walls done right
When a hillside is washing out or a backyard slope is too steep to use, a structural retaining wall holds the soil back and creates flat, usable terraces.
Every wall gets clean drainage rock behind it, and taller walls get a drainage pipe at the base so water pressure never builds up behind the block.
How it works
- 1. Evaluate the grade — we measure the slope, height and water flow to understand what the wall must hold back.
- 2. Engineer the plan — we set wall height, terracing, base depth and drainage, including base pipe where height requires it.
- 3. Excavate and build — we dig to a solid base, set the courses and backfill with clean drainage rock.
- 4. Final walkthrough — we review the finished wall, drainage outlets and the new usable space.

Structural & Slope Retaining Walls FAQs
+Can a retaining wall fix a steep backyard?
Yes. Terracing a slope with one or more retaining walls turns an unusable hill into level areas for lawn, plantings or a patio.
+How do you keep a tall retaining wall from failing?
A solid base, clean drainage rock behind the wall and a base drain pipe on taller walls keep water pressure from pushing the wall over time.
