Heavy-duty polyurethane foam is perfect for Department of Transportation (DOT) and industrial concrete repairs.
Concrete slabs exposed to heavy traffic and consistent loads can become vehicle hazards on roads and cause possible OSHA violations in commercial or industrial settings.
These safety issues require resolution, which inspired HMI to create a heavy-duty polyurethane foam specifically for DOT, municipal, industrial and commercial applications.

HMI’s RR401 line is a rigid polyurethane foam intended for raising large slabs. This material is specifically designed to surpass the regulatory standards required by DOT officials in most parts of the U.S. We recommend the dense polyurethane foam for situations involving stabilizing and lifting sunken concrete on road systems that would otherwise take a long time to fully replace or repair, due to weak soil or a need for demolition.
DOT professionals and contractors turn to HMI for RR401 high-grade foam in three different varieties:
This is a 4 lb. per cubic foot foam engineered to be stronger for lifting larger slabs. This foam will stand up to heavy loads and high traffic, and exceeds specifications required by DOT.
Enjoy quick reaction times with reduced lateral spread hazards. Our RR401 Fast foam makes it easy to avoid raising adjacent slabs that are already in an appropriate position. You can also refrain from wasting material.
Get one of our fastest-acting polyurethane foams available with even less spread for greater control. We suggest the Lightning foam when working in highly sensitive or tight locations requiring fast curing times.
Unlike other polyurethane foams, RR401 Fast is NSF/ANSI/CAN-61 certified. This means you can use them in areas near drinking water systems and water sources throughout the USA and Canada. Here are some appropriate locations to use our polyurethane solutions:
