In the video above, the reporter discusses the differences between slab jacking and mud jacking, two techniques used for repairing cracks in sidewalks, garage floors, and driveways. Slab jackings involves injecting a high-density foam beneath the concrete slab through small holes, about the size of a pinky, using a 3/8-inch drill bit. The foam sets up immediately, resisting moisture and providing stability.
The end product involves putting mortar over small holes, making it less noticeable.
The material used in slab leveling is a high-density foam that sets up quickly, resists moisture, and adds significant stability. This foam is powerful enough to lift commercial garages and highway slabs, contributing to its versatility. In contrast, mud jacking involves injecting different materials like limestone slurry or mortar slurry beneath the slab. These materials add more weight to the slab, can hold moisture, and do not set up immediately. Mud jacking warranties are generally shorter, lasting one or two years as well.
In conclusion, the choice between slab leveling and mud jacking depends on factors such as stability, lifting power, and warranty duration. Slab leveling with Accu Level’s high-density foam offers a more noticeable but stable solution with a longer warranty, while mud jacking involves heavier materials with shorter warranties and greater difficulty for subsequent injections.
