Sea Wall Repair in North Texas
Stabilize Soil • Fill Voids • Stop Water Washout • Protect Your Shoreline
When soil washes out behind a seawall or retaining wall, the structure weakens fast — causing cracks, sinking slabs, unsafe gaps, and long-term damage. PolyFix Inc. repairs seawalls using hydrophobic polyurethane foam, a water-safe material that expands, fills voids, and stabilizes the ground, even when injected directly into wet soil.
If your seawall is showing signs of movement, we can help restore strength, stop erosion, and protect your property before the damage gets worse.
Why Seawalls Fail
Seawalls and retaining walls fail when soil behind them becomes unstable. The most common issues include:
- Water erosion washing soil out from behind the wall
- Voids forming under concrete walkways, patios, or slabs near the water
- Cracks or gaps where water pushes through
- Hydrostatic pressure after heavy rain
- Aging structures with weakened support
- Improper drainage allowing water to pool behind the wall
Over time, this creates empty pockets that leave the wall unsupported — and the damage accelerates quickly.
Common Signs Your Seawall Needs Repair
Contact PolyFix if you notice:
- Soft or sinking ground near the wall
- Voids or gaps behind the seawall
- Cracks forming in the walkway or patio
- Water leaking through seams
- Slabs pulling away from the seawall
- Soil disappearing or settling unevenly
- Leaning or shifting seawall sections
Fixing these early prevents expensive structural damage.
If your seawall is experiencing washout or soil loss, the same issue may also impact nearby slabs like patios, pool decks, concrete slabs, or void areas along the shoreline. We also offer soil stabilization to strengthen the surrounding ground and prevent future erosion.
Q. Do you repair seawalls in lakes, ponds, and residential waterfront areas?
Our hydrophobic foam expands inside wet soil, pushes out standing water, and forms a solid, water-resistant base behind the seawall. This stops ongoing erosion, fills gaps, and helps prevent future washouts — even during heavy rain or rising lake levels.
