Retaining Walls

Why Do Retaining Walls Lean or Fail?

Retaining walls are designed to hold back soil. When the pressure behind them increases—or the base beneath them erodes—they start to lean, crack, or fail.

Common causes include:

• Water buildup behind the wall from poor drainage
• Soil erosion beneath the wall’s footing
• Freeze/thaw cycles pushing against the wall
• Inadequate design for the load it’s holding

Left untreated, the lean gets worse. Cracks form. Sections start to buckle. And what started as a slight tilt becomes a wall that needs to be completely rebuilt.

The Fix: Retaining Wall Stabilization

We use polyurethane foam injection to fill voids behind and beneath the wall, stabilize the soil, and reduce the pressure causing the lean. This can stop further movement and, in some cases, push the wall back toward its original position.

• Minimally invasive – no excavation or demolition
• Done in hours – not days
• Fills voids behind the wall
• Stabilizes the base to prevent further movement
• Long-lasting results that won’t erode

Signs Your Retaining Wall Needs Stabilization

• Visible leaning or tilting
• Cracks in the wall surface
• Bulging or bowing sections
• Gaps forming at the top or base
• Soil washing out from behind the wall

Retaining wall problems only get worse with time. If you’re seeing any of these signs, it’s time to get an estimate.
