Signs of Seawall Distress
Do you own or manage lakefront property in Georgia? If so, you may have issues with your seawalls. As we point out in our blog post Stabilizing Soil Around Seawalls at Lake Lanier and Lake Allatoona, you may want to check for the following:
- Settled soil near the wall (a sign of water leaking through the wall and eroding the soil on the land side).
- Soil deposits near the seams on the water side of the wall (a sign of water leaks bringing soil through the seams into the lake).
- Visible rust colored cracks or stains in the wall (a sign of water leaking through cracks in the wall and rusting the rebar inside). Read more.
Polyurethane Seawall Repair
High-strength polyurethane foam can be injected through pipes directly into voids and loose soil around your distressed seawall. GCS uses semi-rigid hydrophobic material that reacts with moisture in the ground and expands to fill voids while also permeating the soil to form a solid, strong, watertight mass.
Since this polyurethane is impermeable to water once in place, the likelihood of future erosion is vastly diminished versus refilling the void with soil or other material. Originally developed over 30 years ago, and continuously improved since, this technology has one of the longest histories of success in the field.
Efficient seawall repair with this material prevents the need for remediation processes that can be harmful to the environment, such as a complete wall replacement or the excavating of all loose soil. These polyurethanes are Phthalate free AND approved for contact with drinking water once cured in place. So you don’t have to worry any long-term averse environmental impact.
