Seawall Erosion Repair with Foam - A Modern Solution

Living near the water certainly has its perks, but it also comes with responsibilities that not all property owners are prepared for. One of the biggest issues that waterfront properties face is seawall maintenance. Over time, erosion can weaken the seawall, compromise your property and even pose safety risks. Fortunately, seawall erosion repair with foam has emerged as a fast, cost-effective, and long-lasting solution.

If your seawall is in disrepair or its structural integrity has been compromised, it’s likely no longer a good barrier to the water. Working with a professional company like Foremost Foundations and Construction who offers seawall repair for residential and commercial properties, can protect your property and investment. We are also a proud member of the Seawall Repair Network.

What Causes Seawall Erosion?

Seawalls are designed to protect land from the constant pressure of waves, tides, and shifting soil. But over time, water finds its way through tiny cracks and joints in the wall. This can cause soil loss behind the wall, voids and sinkholes under structures, and cracks and movement in the wall itself. Ultimately, seawalls can settle or collapse, threatening your entire property.

How Foam Injection Works

Seawall erosion repair with foam uses a high-density polyurethane material that’s injected deep into the soil behind and beneath the seawall. The process starts with drilling small holes into targeted areas around the seawall.

Polyurethane foam is injected into these holes, expanding to fill voids, displace water, and compact loose soil. As the foam cures, it hardens and stabilizes the soil, effectively lifting and sealing the area. The result is a strengthened foundation, reduced water intrusion, and restored integrity.

Why Foam Is a Smart Solution

Foam injection isn’t just a trendy fix; it’s a proven technology used across industries for structural repair. Here’s why homeowners and contractors are choosing it for seawall erosion repair:

• Fast results. Not only is the repair quick, but also most poly foam products reach the majority of their final strength within 15-30 minutes. Jobs are typically completed in just 1-2 days.

• Minimally invasive. Since poly foam injections only require small holes, there’s no need for large equipment or messy excavation. In fact, most areas are ready for light use or traffic the same day.

• Waterproof and long-lasting. Polyurethane foam won’t wash away or degrade like other fill materials. It’s considered a permanent solution.

• Environmentally safe. Closed-cell polyurethane won’t leach harmful chemicals into the soil or water, making it safe for plants, animals, and marine life. 

• Cost-effective. Poly foam seawall repair is much cheaper than tearing out and rebuilding a seawall.

When to Consider Foam Seawall Repair

If you notice any of the following signs, it’s time to act:

• Cracks or leaning in your seawall

• Soil loss or sinkholes near the base

• Water seeping through seams or joints

• Erosion behind the wall after heavy rain or storms

Foam injection is ideal for repairing these problems before they escalate into more serious (and expensive) damage.
