🔍Why Is Soil Washing Out Behind My Seawall?
If soil is washing out behind your seawall, simply adding more dirt is rarely a permanent solution. The source of the water movement must be identified and corrected.
This problem is commonly called seawall washout. It happens when water moves through, beneath, or around the seawall and carries soil away from the property. What begins as a small soft spot can eventually affect landscaping, walkways, docks, pool decks, and other nearby structures.
Common signs of seawall washout:
❌ Small sinkholes or depressions
❌Gaps beneath pavers or concrete
❌Cracks in seawall
❌Water flowing through seawall joints
❌Settling landscape
❌Leaning or bowing seawall
Soil loss behind a seawall should not be treated as a cosmetic landscaping issue. It may indicate failed joints, cracks, drainage problems, foundation erosion, or structural movement.
The earlier the cause is identified, the more options may be available for protecting the shoreline and nearby improvements.
