Spray Polyurethane Foam Concrete Jacking

Spray Polyurethane Foam concrete jacking is a fast, economical repair process for correcting settled and unstable concrete.

From sidewalks to concrete highways, and everything in between, concrete foam jacking is economical, fast and effective for economically correcting settlement and instability.

Over time, the fill beneath a concrete slab erodes or settles due to poor compaction during construction, water intrusion, or heavy use, causing the slab to lose stability and settle.

Soil erosion and settlement often cause concrete slabs in patios, sidewalks and driveways to sink into the ground.

This type of settlement isn't just unsightly; it can also cause more damage and can be a safety hazard.

Water tends to pool on sunken surfaces and un-leveled floors cause a trip hazard.

The problems with Mud Jacking

Until now, the only solution available to repair sinking slabs was mudjacking, a process that involves drilling holes in the slab to inject a mixture of cement and mud underneath, to raise it back to level.

Not only is this process unwieldy, using large holes and a much heavier solution, but the concrete could not be used for some time after jacking to give the mud and cement time to set properly.

Modern Concrete Jacking with SPF

Concrete Jacking is the process of injecting a Spray Polyurethane Foam material underneath settled or unstable slabs to raise and support them.

  • - It is faster
  • - Cleaner
  • - More precise
  • - Lighter
  • - Less invasive
  • - Less expensive than replacing concrete.

It is a repair that will outlast the life of your concrete, but is easily excavatable when the time comes to replace the slab.
