Too many builders in the Balcones Fault zone assume that if the topsoil looks stable, the cut won't move. Then the first heavy rain undercuts the toe, and the retaining wall starts to tilt. We've seen it happen on slopes off Bee Caves Road and along the Colorado River terraces. A proper soil erosion analysis in Austin identifies exactly where the shear plane sits and how the infiltration rate changes after the clay dries. Without that data, you're guessing. Our team runs the full suite — from rill assessment to gully erosion modeling — so you know before the dozer shows up. We combine this with a drainage geotechnical study to map subsurface flow paths that accelerate erosion.
