Erosion and Soil Loss
Soil loss behind seawalls and retaining walls is a major warning sign of structural failure. Erosion undermines the wall's support system, leading to instability, cracking, or collapse — and increasing the risk to nearby property and infrastructure.

What Causes Soil Loss Behind Walls?
Soil erosion is usually caused by uncontrolled water flow behind or under the structure. This can come from surface runoff, poor drainage, tidal movement, or groundwater pressure. As the soil escapes, the wall begins to lose its support and may start leaning or settling.
Common Indicators
- Voids or sinkholes behind the wall
- Visible soil washout after rainfall or tides
- Shifting pavers or landscaping above
- Bulging or movement in the wall structure
Why It Matters
Erosion behind a wall doesn’t just affect aesthetics — it signals a breakdown in stability. Left unaddressed, it can lead to total failure of the structure and damage to the surrounding environment or property.
Recommended Solution
Solve underlying instability with Soil Stabilization Treatment to densify and lock soils in place. In cases of void formation or water infiltration, Polyurethane Foam Injection can be used to backfill and seal gaps behind the wall.
