RR201 | 2lb Concrete Raising Foam

RR201 is specifically designed for residential concrete raising. This 2.5 lb. per cubic foot density foam has a fast reaction time with less spread. This provides more control in the lifting of the concrete slabs in your driveway, patio, pool deck, walkways, garage approaches and sidewalks.

Heavy-duty polyurethane foam perfect for D.O.T. & industrial concrete repair. Rocking concrete slabs caused by high traffic and heavy loads can lead to traffic hazards on our roads and possible OSHA issues in commercial or industrial settings.

These safety issues require resolution, and ultimately led us to create a foam specifically for D.O.T., municipal, industrial, and commercial applications.

RR501 | 5lb Stabilizing Foam

Get some stability in your life with HMI’s RR501 Poly Foam.

Our RR501, a 5 lb. per cubic foot density foam, provides a slower reaction time and further spread. Due to the distance this foam can travel, RR501 is excellent for undersealing and stabilizing joints on rocking slabs from slab curl. RR501 polyurethane foam is formulated for stabilization, not lifting; therefore, RR501 does not have a high expansive force.

RR601 | 6 lb. Foam

You should never settle, except when it comes to HMI’s RR601.

RR601 polyurethane concrete raising and soil stabilizing foam was specifically engineered and formulated as a special request to us from D.O.T. engineers. RR601 is a 6 lb. per cubic foot density foam developed especially for infrastructure repair. The increased compressive strength is well suited for substantial loads and high traffic.
