This video from our material supplier Alchemy-Spetec documents the raising of a driveway slab at a busy ATM drive-through. Customers’ cars were getting damaged when they suddenly dropped down onto the sunken section of the driveway. Needless to say, the property owner was highly motivated to resolve this liability in a timely yet reliable manner.

Sunken concrete slabs can be lifted back into place with two component polymer foam designed to work in wet or dry conditions. The expansion force of the foam coupled with the pressure of a specialized pump generate enough controlled force to lift virtually any structure back into position with 1/8″ precision. Slab settlement can be restored at a fraction of the cost and time required for replacement.
