Uneven concrete is unsightly. Whether the sunken slab is a sidewalk, driveway, or pool deck, it lowers your property value and creates a safety hazard. If someone trips and gets injured, you could get sued. Therefore, don’t put this repair on the back burner. Get it done today.
It takes time to dig up and replace a sunken concrete slab. Newly poured concrete can’t be used right away. It needs time to harden and dry. Also, if the slab sunk because the soil wasn’t able to support it, the same thing will happen with the new slab. In other words, you haven’t solved the underlying issue.
Mudjacking lifts the uneven slab by injecting a cement slurry under it. The problem with mudjacking is the weight of the slurry. It contains cement, so it’s pretty heavy. If the slab became unlevel because the soil wasn’t able to hold it up, adding even more weight to the soil via a cement slurry isn’t the right solution.
