Seawall Rehabilitation

Seawalls can be compromised in a variety of ways, but one of the most frequent issues is from the loss of support soils from behind the seawall or bulkhead.  When base soils are washed out by continuous water movement, voids begin to develop below the seawall and can lead to further problems, such as sinkholes or settlement of the soils along the seawall.

Our polymer injection seawall repair process solves the issue of soil loss and soil settlement from the behind a seawall or bulkhead. We repair this problem by injecting a high-density structural polymer directly into the void area through 1/2 inch metal rods without excavating the soil or damaging the seawall or bulkhead.

Once injected, the polymers aggressively seek out the voids and push out any present water.  The polymer expands throughout the voids and reestablishes the weight-bearing capacity of the soil while preventing future washout. Additionally, if any structures have settled along the seawall, it is possible for the structure to be lifted and leveled back to original grade.

Our polymer injection process helps owners avoid the costly hassle of dealing with coastal marine contractors, bulkhead construction, bulkhead replacement or seawall replacement. Our process works with all types of materials and designs, including wooden bulkheads, metal bulkheads, Concrete bulkheads, wooden seawalls, concrete seawalls and metal seawalls.
