RR600 Soil Stabilizer with Catalyst

Reaction Time Lapsed Video. This is a brief video demonstrating the reaction of the single component RR600 with catalyst added. If you would like to learn more about HMI equipment, materials or training, please call 800-626-2464.

RR600 Soil Stabilizer without catalyst

Reaction Time Lapsed Video. This is a brief video demonstrating the reaction of RR600 without added catalyst. If you would like to learn more about HMI equipment, materials or training, please call 800-626-2464.

RR401 Polyurethane Concrete Lifting Foam

The RR401 is a polyurethane foam specifically designed for raising and stabilizing concrete. Ideal for heavy lifting, the reaction time is designed to mimic traditional mudjacking. HMI is the only company manufacturing foam that is uses recycled polyurethane materials. This is a two component 4 lb foam. HMI manufactures polyurethane concrete raising equipment and material along with the Industry’s best training. If you would like to learn more about HMI equipment, materials or training, please call 800-626-2464.

RR401G Material Reaction

RR401G is a two component gas blown 4 lb polyurethane foam. It is designed to set up in wet conditions or underwater without compromising density or quality of foam. If you would like to learn more about HMI equipment, materials or training, please call 800-626-2464.

RR401G – Foam that will set up under water.

RR 300 Void Filling Foam Reaction Video

RR 300 is the two component foam manufactured by HMI designed for void filling. You will notice in this video that the material travels up and out of the cup before it starts to harded. This is why the material is so successfull in filling voids, it travels long distances finding voids and then reacts. For questions on this foam, HMI equipment or applications please call 800-626-2464

HMI RR201 Reaction Video

The RR201 is a polyurethane foam specifically designed for raising and stabilizing concrete. Ideal for residential and small slabs, the reaction time is designed to mimic traditional mudjacking. HMI is the only company manufacturing foam that is uses recycled polyurethane materials. This is a two component 2 lb foam. HMI manufactures polyurethane concrete raising equipment and material along with the Industry’s best training. If you would like to learn more about HMI equipment, materials or training, please call 800-626-2464.

World of Concrete 2012 Live Polyurethane Concrete Raising

This video is of the Live Polyurethane Concrete Raising Demonstrations that were presented at the 2012 World of Concrete in Las Vegas. 77 Demonstrations were given during the 4 day event to thousands of attendees that wanted to look into polyurethane concrete lifting otherwise known as foam jacking. This method of repair is typically half the cost of replacement. HMI is the premier equipment and material manufacture in polyurethane concrete raising industry with experience and knowledge of slabjacking since 1974.

How to repair a low spot on a highway with Polyurethane

Cut down on lane closures and highway slab repair costs by raising and stabilizing low spots with light weight polyurethane. This repair project completed for the Wisconsin DOT took 2 1/2 hours start to finish.
