Highway Polyurethane Stabilization HMI REP Jul 18, 2013 0000 On highway I-43 in Manitowoc county,WI, the weight of moving traffic and the unstable soil caused the slab of concrete underneath the asphalt to rock back and forth as heavy vehicles traveled over it. The signs of an unstable slab of concrete are cracks forming and pot holes in the concrete. RaiseRite (www.raise-rite.com) drilled a series of injection holes through and around the troubled area. A dense lightweight polyurethane material was then injected in the holes to stabilize the concrete beneath the asphalt. The polyurethane injected has a cure time of 15 minutes to make sure the job is done fast and correctly. The polyurethane material used will not erode and assure the slab will not move. After the injections were complete the Read More
