Erosion Control & Backfill Stabilization
Stopping soil loss behind and around a seawall before it undermines the structure and swallows your yard.
Call (561) 555-0147Erosion behind a seawall is one of the sneakiest forms of damage because it's invisible until a sinkhole opens in the yard or the wall itself starts to lean. Soil washes out through cracked joints, gaps at the wall's toe, or failed drainage — and every gallon that escapes leaves a void that puts more pressure on the structure above it.
Our erosion control work identifies exactly where soil is escaping, seals the pathway, and replaces and compacts lost fill — stopping the problem at its source instead of just patching the symptom.
Signs You May Need This Service
- Sinkholes or soft, sinking spots in the yard near the water
- Visible gaps or voids under a dock or patio slab
- A seawall that has developed a lean or bulge over time
- Cloudy or discolored water near the base of the wall after rain
- Grass or landscaping that keeps dying in the same low spot
Our Process
Void mapping
We probe the yard and wall to locate voids and trace where soil is escaping through the structure.
Seal the pathway
Cracks, joint gaps, or toe erosion are sealed or repaired so soil stops washing out.
Fill & compact
Void areas are filled with appropriate material and properly compacted in lifts to restore stable support.
Grade & drainage check
We check surface drainage near the wall to reduce future water intrusion and re-erosion risk.

Frequently Asked Questions
Why is soil disappearing from behind my seawall?
Almost always through a crack, joint gap, or failed panel that lets water — and the soil suspended in it — pass through to the waterway on the other side, especially during tidal exchange.
Is a sinkhole near my seawall an emergency?
It can be, especially if it's growing or located near a structure, pool, or seawall footing. We recommend having it evaluated promptly rather than filling it yourself, since the underlying cause needs to be fixed first.
Will filling the void fix the problem permanently?
Only if the pathway causing the soil loss is sealed first. Filling without repairing the source just delays the same void from reopening.
