Concrete Lifting Foam for Maximum Productivity and Profitability

HMI offers a growing list of concrete lifting and void filling foams to provide contractors like you with options.

Over the last 15 years, HMI has invested significant laboratory time formulating several concrete lifting, leveling and void-filling foams. Our goal is to help you match the optimal characteristics of each foam to the needs of each project. With HMI, you always get the level of customer service you deserve and our undivided attention when you need suggestions for foam jacking materials that make all the difference in prolonging the life of existing slabs.

Tailored Foam Solutions for Every Project

Choosing an HMI foam requires you to think about application speed, strength, hydrophobicity and yield characteristics. Your concrete raising business may require the use of multiple foams to tackle client demands in the residential or commercial sector. Fortunately, HMI provides different foam jacking materials for strong results and outstanding productivity.

Explore foam options available through HMI:

  • RR 201, Fast and Lightning: Get a foam with an impressive reaction time. We see clients utilize the RR 201, Fast and Lightning HMI foam for exceptional control when raising garage floors, sidewalks, patios, driveways and pool decks.
  • RR 401, Fast and Lightning: Spread foam jacking materials with flexibility. RR 401 is more than three times stronger than RR 201 and is intended for slabs that see consistent foot traffic and vehicles.
  • RR 501: Take advantage of slow reaction times to let filling material spread deep within voids. Our RR 501 material is a fantastic option when your project calls for accessing voids that, when filled, reinforce joints and prevent slab curl.
  • RR 600: Work in areas where soil strength and integrity are less than ideal. Our RR 600 foam is a low-viscosity single-component polyurethane solution. Stabilize everything from loose sands to structural foundations.
  • RR 601: Consider HMI’s RR 601 foam jacking material when working on highways and large slabs. This foam material goes above and beyond most DOT specifications for lifting projects and matches the spread rate of standard foam.
  • HF 402 and 402 Fast: Complete projects that require you to work around water and moisture. This one-of-a-kind polyurethane foam solution maintains its dimensional stability and is appropriate for diverse environments.
  • FS 201: Prevent unwanted dripping with a special spray. You can use FS 201 from HMI directly on exterior walls to keep moisture from penetrating surfaces. Create a waterproof foundation or seal up cracks as needed.
  • Fillfoam: Count on HMI for a void filling material that does not generate heat during the application. Our Fillfoam is appropriate for worksites featuring tanks, pipes and culverts that require service and abandonment.
