When handling seawall repairs, a hydrophobic polyurethane foam is needed. Thanks to HMI, you can get a hydro-insensitive foam that continues to perform after frequent water exposure. The days of troubleshooting seawalls and concrete repairs in aquatic environments are behind you, as you can complete projects without clouding water, contaminating resources, or crumbling or shrinking in the future.
Our product line covers the injection, reaction and curing phases, and it is precisely what you need to complete the most complex seawall repair work.
HMI noticed a gap in the available options for polyurethane concrete repairs in locations close to water. We developed our HydroFoam line to resist hydrolysis, which is when water breaks down another substance. With foam, water interferes with the integrity of the foam bond, and the material shrinks over time. We separate our HydroFoam from other solutions on the market, as professionals can apply the foam in the presence of liquid without compromising the material’s dimensional stability.
Seawall repairs can be tricky, as the right material is needed to facilitate drainage, prevent water from freezing underneath slabs and keep surfaces level. These surfaces can encounter tens of thousands of gallons of water.
Traditional polyurethane is water-resistant, but HMI’s HydroFoam provides extra peace of mind that repairs can withstand wakes, waves and currents, as well as stop premature sinking when used correctly.
