Highway & Railroad Leveling

Solve Infrastructure Concrete Woes with Foam

Problems with sunken concrete aren’t limited to driveways and sidewalks. When concrete highways or railroad infrastructure starts to settle, it can cause costly problems. Fortunately, polyurethane foam is strong enough to level and stabilize concrete slabs that are part of larger infrastructure projects.

Railway Lifting

From the vibrations to the weight of the trains, settling of slabs along rail lines are hardly rare.

Whether it is a railroad crossing or freight track at an industrial site, if the concrete slab holding the tracks begins to sink, it could cause headaches. The solution? Precision concrete leveling with polyurethane foam.

Polyurethane foam has a number of distinct advantages for infrastructure projects like railways.

  1. It sets fast. The crossing or other track section will be out of commission for far less time than if the concrete had to be replaced or other leveling methods were employed.

  2. It is cost-effective. Concrete leveling, even at the scale that would be needed for an infrastructure project, is less expensive than replacing the concrete slab. This is particularly true in cases where other components would have to be removed.

Concrete Highway Leveling

Highways endure relentless pressure from nonstop traffic. So if the road’s base has been compromised, it can wreak havoc on the concrete above.

If you catch it before the concrete is too far gone, however, polyurethane foam can be part of a solution that cuts down on both costs and construction time.

Let’s say, for example, erosion has impacted the ground below the roadway. It won’t be long before the affected portions of the roadway begin to sink and crack. You then have two options.

  1. Rip everything out, re-fill and compact the affected area. Then pour new concrete to rebuild the roadway.

  2. Inject expanding polyurethane foam into the voids caused by the erosion, lifting the sunken sections back to level. Then patch the cracks to provide for a smoother ride.

Both approaches will fix the highway—but only one avoids weeks of closures and massive expense. Once it cures, the polyurethane foam is strong enough to handle the stresses placed upon the roadway. It also is impervious to the salt and other chemicals, so it won’t break down.
