Project I-94 – Milwaukee

Polyurethane Concrete Raising & Stabilization of Highway I-94 in Milwaukee

2014040595025053-2 Problem

RaiseRite was called by a roadway contractor, who informed us that concrete roadway panels beneath the asphalt paving on I-94 in Milwaukee had voids and was rocking back and forth, as trucks would drive over the road. The roadway contractor needed to stabilize the area within 36 hours.


RaiseRite provided a quote to the roadway contractor. The quote was approved by the state DOT, with the determination that a polyurethane injection was the best solution to fix the area in question.

The two man RaiseRite crew arrived on-site the next day at 11:00 p.m., when traffic volume was low. 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, traffic barriers removed, and the roadway was opened back up for traffic.

Even with short notice, RaiseRite was able to arrive on-site and successfully complete another highway stabilization project.
