Sea walls are essential for protecting waterfront properties, but over time, they become vulnerable to erosion, settlement, and cracking. Timely repair is critical. Fortunately, HMI’s HydroFoam hydrophobic foams and Soil Link Grouts now offer smarter, more cost-effective alternatives to full wall replacement.
HMI offers advanced solutions like hydrophobic foams and soil stabilization grouts to combat these challenges and provide cost-effective alternatives to full seawall replacement.
Waves, tides, boat wakes, and rainwater runoff constantly batter sea walls, while soil behind the wall gradually erodes. This process creates voids, leading to ground subsidence, visible depressions, or sinkholes. If left unaddressed, these issues can undermine the wall’s foundation and structural integrity.

Stone sea walls are especially prone to erosion due to gaps between stones. Water seeping through these gaps carries soil away, worsening instability. Temporary fixes like packing gaps with aggregate only delay the problem. Without stabilizing the underlying soil, erosion will persist—and repairs can be costly, especially in hard-to-access locations.
Early warning signs include soil loss, cracks, or sinkholes near the wall. Addressing these promptly is key to preventing major damage. Unlike temporary fixes, HMI’s Soil Link Grout provides a long-lasting solution by stabilizing the underlying soil and preventing further erosion.
HMI’s Soil Link Grout is specifically designed for permeation grouting in seawall repair, a proven method for stabilizing soil. Our single-component grout is designed for permeation grouting—a proven method for sea wall repair. This hydro-activated polyurethane foam fills voids and gaps, creating a tight seal that stabilizes soil and blocks water infiltration. It is less expansive than the HS030 soil stabilizer, making it ideal for smaller voids and minimizing pressure on the wall. Adjustable reaction times allow for project flexibility.
Using HMI’s single-component grout solidifies the soil and prevents further loss before damage becomes severe.
HMI’s HydroFOAM is engineered specifically for the harsh, wet environments of seawall repair, making it an ideal alternative to costly replacements.. Unlike traditional methods, HydroFOAM can be injected directly into cracks, voids, and behind sea walls using the HMI Deep Foamjection™ system. The foam expands to displace water, fill gaps, and create a watertight seal.
For stone sea walls, combining aggregate fill with HMI Soil Link Grout forms a hardened, erosion-resistant barrier, preserving the wall’s protective function.
HMI offers more than just materials—we partner with business owners for success. From hands-on training and equipment demonstrations to expert resources, we provide unmatched support to ensure contractors can effectively apply HydroFoam and Soil Link Grout for optimal seawall repair results..
With over 50 years of experience and industry-leading products like Foamjection™ and renewable-based poly foams, HMI empowers contractors to deliver the best in sea wall repair.
