Sloped or shifting soil can undermine a landscape over time. NBX builds retaining walls that control erosion, create usable level space, and add lasting structure to your Rancho Santa Margarita, CA property.
Understanding The Service
Why the unseen parts of a retaining wall matter more than the visible surface
A retaining wall that fails almost always fails for the same reason, water pressure building up behind it with nowhere to go. Many improperly built walls focus entirely on the visible stacked surface while neglecting the drainage system that keeps the structure stable. Our process for every retaining wall project in Rancho Santa Margarita, CA begins below ground, with excavation deep enough to establish a compacted base that will not shift or settle under the weight of the wall and the soil behind it.
Once the base is properly compacted, we install a gravel drainage layer and perforated drain pipe behind the wall structure. This allows groundwater to escape rather than accumulating and pushing against the wall face, which is the single most common cause of bulging, leaning, or collapsed retaining walls. For taller walls or walls holding back significant slope, we incorporate geogrid reinforcement that ties the wall back into the soil mass for additional stability.
Material selection depends on both your property's aesthetic and its structural needs. Segmental concrete blocks offer strength and a clean, uniform appearance suited to most residential applications. Natural stone provides a more organic look that blends with established landscaping. Timber walls work well for shorter, budget-conscious applications, though they typically have a shorter lifespan than masonry options.
Every wall is built with a slight backward lean, known as batter, which works with gravity rather than against it to resist the pressure of retained soil. We finish each project with proper backfilling and grading so water sheds away from the wall rather than pooling against it, completing a structure designed to perform for decades rather than years.

Our backyard slope was washing out every time it rained heavily. The wall they built completely solved the erosion problem and gave us a flat area to actually use.
They explained why the drainage behind the wall mattered more than the stone itself, which gave me a lot of confidence in the quality of the work.
The natural stone wall they installed looks like it has always been part of the property. Excellent craftsmanship from start to finish.
We had a previous wall fail after just a few years from a different contractor. This one was built properly the first time and has held up perfectly.
