I-94 Milwaukee, Wisconsin Stabilization Project

Company: RaiseRite
Project: I-94 Milwaukee, Wisconsin
Product: RR401 | 4lb Concrete Raising Foam



RaiseRite Concrete Lifting was called by a roadway contractor informing us that concrete roadway panels beneath the asphalt paving on I-94 in Milwaukee, Wisconsin had voids, leading to a rocking back and forth of the panels as trucks would drive over this portion of the road. The roadway contractor needed to stabilize the area within 36 hours. The work needed to be completed at night to avoid lane closures and traffic congestion.


RaiseRite provided a quote to the roadway contractor. It was approved by the state DOT that polyurethane injection was the best solution to fix the area in question. Filling the voids to stabilize the concrete panels would provide minimum traffic disruption and expedite the necessary repairs.

The two man RaiseRite crew arrived onsite the next day at 11:00 p.m. The contractor provided and set up traffic control. The voids were filled and the roadway was stabilized with 955 lbs. of HMI RR401 polyurethane material. After the voids were successfully filled, the crew lifted the shoulders to line up with the roadway.

The project was completed at 4:30 a.m., for a total project duration of 5 ½ hours on deck. Once the polyurethane cure time of 15 minutes was complete and traffic barriers removed, the roadway was opened for traffic. Even upon short notice, RaiseRite was able to arrive onsite and successfully complete another highway stabilization project.

About HMI

When HMI founder Ernie Cvetezar started his own concrete raising business in 1974, he asked for concrete raising tips from the manufacturers of the pumps he used. To his surprise, the answers he received were, “We make the equipment, we don’t know how to use it.” From that moment on, Ernie vowed to fully support every customer that purchased the equipment he manufactured. This began with his invention of the first fully hydraulic mudpump. Since then, HMI has been a world leader in concrete raising equipment, systems and materials.

From mudpumps, polyurethane foam systems to Discovery & Training seminars to help entrepreneurs start concrete raising businesses, Ernie and the HMI team have never broken the promise to fully support our customers. All equipment and materials designed and produced by HMI, are field tested through RaiseRite, Inc. to ensure superior quality and performance.
