Seawall repair using polyurethane foam injection is an innovative method that offers a durable and efficient solution for stabilizing and restoring damaged seawalls. This technique involves injecting a special foam into the ground beneath the seawall, which then expands and hardens, filling voids and reinforcing the soil. It’s a less invasive and more cost-effective approach compared to traditional repair methods, making it an excellent option for homeowners looking to extend the life of their seawalls.
