How Polyurethane Is Used to Repair Seawalls

Polyurethane seawall repair offers many advantages over traditional methods. It allows for a clean approach to bolstering your seawall from a landslide. When properly installed, the polyurethane is quickly injected into voids in the subsurface soil and to avoid major excavation, expensive labor, and costly delays. This environmentally friendly solution can prevent further damage and strengthen your seawall considerably.  

Foremost Foundations provides many options for residential and commercial seawall repair to give Gulf Coast residents peace of mind when storms create swells that pound the coastline.

How Does Polyurethane Seawall Repair Work?

Polyurethane resin is waterproof and eco-friendly. Our technicians use it to penetrate a seawall when soil erosion allows for water incursion behind the seawall. The resin, injected into half-inch thick bore holes, displaces water, and solidifies loose soil. Polyurethane seawall repair sounds less invasive than sodium silicate. In addition, polyurethane also lasts longer than cement grout, which breaks down over time.

Signs that It’s Time for Seawall Repair

Every waterfront property owner may worry about a failing seawall. When waves and storm water wash away soil, it puts your building at risk. Here are some other signs that it's time for polyurethane seawall repair:

  • Every wave and high tide washes through gaps and carries away your soil.

  • Concrete walkways and patios have cracks.

  • Your concrete retaining wall has both vertical and horizontal cracks.

  • You have noticeable depressions and cavities or large sinkholes near your seawall.


Heed these early warning signs to avoid catastrophic damage to your property.

What People Are Saying


I Highly Recommend

I highly recommend Steve Folk, Bray Watkins and the entire Foremost team. I hired them because part of my driveway sunk nearly 6 inches at the entrance to the carport. Foremost was able to raise the driveway nearly even, which reduced risk of a blown out tire on our vehicles. Additionally, they installed 13 screwjacks under the house, which was dipping towards the middle and creating a bowl effect. We saw an immediate improvement. Their work and customer service were fantastic!
