A car park slab in Sunbury, Victoria (Australia) had settled about 40 mm (1.57 in). This dangerous drop created both trip hazards and litigation risks. Because this property was normally in use five days a week, the client needed very quick turnaround. A tight deadline like this automatically rules out the options of replacing the slab and lifting with cement grout (a.k.a. “mudjacking).

The most efficient repair method for sunken slabs is lifting with polyurethane. The RevivaLift team from RevivaCrete specializes in this method of leveling concrete. In this case, they used the Alchemy-Spetec PolyBadger lifting unit to get the job done. The PolyBadger is a tough, compact pump on wheels that fits easily in the back of a pickup truck if needed. It’s ideal for small to medium projects that need to be completed quickly. RevivaCrete gets their slab lifting supplies & support from Bayset, Australia’s premier specialist trade supplier.

The RevivaLift crew pumped Alchemy-Spetec’s AP Lift 430 high-strength polyurethane foam underneath the slab. With precision technique, they gradually brought it back into place until it was completely level. AP Lift 430 sets up very quickly, reaching 90% full strength in 15 minutes and full cure into a solid mass in less than a day. Once cured, these foams offer thousands of pounds per square foot of support. As soon as the crew is done packing up their equipment, the slab is usually ready for traffic. Needless to say, the property owner was very happy with this fast, efficient, and durable repair.
