Sunken concrete sidewalks, pool decks, and driveways are pretty unsightly. However, they’re more than that. They not only lower your property value, but they’re also a safety hazard. If someone trips and breaks an arm, you could find yourself facing a lawsuit. So, this isn’t a repair you want to postpone.
Not long ago, sunken concrete slabs were fixed either by digging them up, or something called “mud-jacking.” They were useful at the time but now is not so much the case.
The soil underneath a sidewalk or any concrete slab is very important. If the old soil was weak, a newly poured slab won’t solve anything and the problem will just occur again. While waiting for the new slab to dry and harden, you cant use it. A very time-consuming process.
