Lifting force can be adjusted by fine-tuning the chemical reaction that causes the foam to expand. Adjusting the density and expansive force of the 2-part foam affords a wide range of geotechnical uses. Full loading of the foundation, roadway or other structural element can usually happen about 15 minutes after the material is injected. Down time is minimized with Polyurethane® concrete repair. Polyurethane does not react with soil or moisture it will not leach harmful chemicals into the soil. Polyurethane’s waterproofing properties can be beneficial in certain applications. Once cured, Polyurethane will not wash away. Despite its light weight, Polyurethane can support substantial loads it typically provides greater lifting power than mudjacking. Polyurethane ’s light weight makes it useful where denser fill material might impose an undesirable load on weak soils. Polyurethane offers important ADVANTAGES: Treat soil to improve load-bearing characteristics in preconstruction applications.Repair and stabilize rail beds weakened by soil washouts.Lift, level and stabilize roadways and airport runways.Lift settled slabs and slab foundations.Polyurethane® is designed specifically to repair this type of problem in Hillsboro, Olympia, Beaverton, Gresham, Corvallis, Tacoma, Bend and the neighboring towns. Uneven sidewalks, walkways and steps can cause tripping, and sunken driveway slabs can make parking your car in the garage quite a challenge. This can cause problems at your home as well.

In the example of trains, train service can be interrupted because of erosion and settlement beneath the track bed. This often results in sections of runways and parking lots being closed down. The soil beneath the concrete compresses and can cause major problems.Ĭommercially, concrete roadways can become dangerous or unusable. Sometimes, the combined weight of concrete and what it supports causes concrete settlement to occur. We Use Polyurethane Injection Foam to Raise Settled Concrete in Greater Portland Get a faster, affordable alternative to repair your concrete slabĬoncrete is a heavy material and so are the vehicles, machinery and structures that concrete slabs and footings are expected to support.
