What is Slabjacking? Part 1 of 3 (Introduction)
Have you ever seen where a portion of a perfectly good concrete pavement has dropped excessively and is making walking or driving difficult? Have you seen a dropped sidewalk, driveway, patio floor, or other walkway?
It seems like waste to have the concrete jackhammered out and replaced with a new slab or pavement. Surely, with the present day concern for sustainability, there must be a better solution.
There is! It is called “slab jacking.”
Slab jacking is the process where a specialty contractor pumps a grout or a polyurethane under the concrete pavement to lift it back to level or near level. Sometimes slab jacking includes saw cutting of the pavement to loosen sections of the pavement that have become bound or stuck.
I have had it done a few times on the driveway and sidewalks at my home. Portions of the driveway required repeated jacking over the course of a decade by different slabjackers, but after two or three application the driveway and garage floor have been stable for over a decade.
