A system designed for lifting and stabilizing sunken concrete slabs utilizes expanding polymer foam. This method involves injecting the foam beneath the concrete to fill voids and raise the slab back to its original level. Examples include addressing settled driveways, sidewalks, patios, and interior floors.
The advantage of this technique lies in its cost-effectiveness compared to complete concrete replacement. It provides a less disruptive and faster solution, minimizing downtime and inconvenience. Historically, mudjacking, a process using a cement-based grout, served a similar purpose, but polymer foam offers benefits such as lighter weight, greater precision, and longer-lasting results due to its resistance to erosion and breakdown.
