What Causes Soil Erosion behind a Seawall?


Watch soil erosion behind a seawall

One of the most common causes of seawall failure is soil erosion. At high tide, the water pressure exerted on the outside must equal the pressure exerted from the soil on the landward side. If the soil has voids, and therefore less pressure, the sea wall will not be properly supported. Cracks will occur and in the worse case, the sea wall could fail.


Additionally, if soil voids occur in the deadman tieback location, the sea wall panels could rotate and separate quickly.


The second reason is that soil erosion will eventually affect your entire property. Pavers can sink, pool decks can crack, and soil can wash out from around the pool.


Addressing soil erosion is the first step in property maintenance. By injecting our unique, environmentally friendly resin into the ground, Seawall Doctors can stabilize weak soil zones. The resin will expand and fill voids, bond with the soil, and quickly solidify into a watertight, closed-cell, rigid foam.

Remember, a small sinkhole on the surface can be a sign of a much larger void below the surface. Once an area begins to wash out underground, it will typically expand and quickly migrate if left unattended.

Our experienced personnel will assist you with your seawall repair issues which are caused by organic soils, poor compaction, improper footing embedment, and erosion or runoff.

We offer complete erosion control with services like seawall installation or repair,
