Raise a concrete slab
 

Any recommendation on contractor that could raise a concrete slab that is about the size of about 4 feet by 8 feet. Just need to lift the one side up about 1.5 inches at the most for better drainage.
Please advise and thank you,
Have searched this site and could not fine any other similiar post.

:icon_wink: If you're real "handy" one hit on google was a youtube on doing it yourself. Good luck. :ho:

If this original with the house, call home warranty first. I believe the concrete pads are considered structural and covered for 10 years.

We put Chattahoochee River Rock on ours and they graded it away from the house and it worked and looks really nice. Very easy to clean.

Keep in mind I have your best interest and results at heart. Unless you’re strong and gentle there is a good chance it will crack if you pry it up to build up under the low side.

Not a simple repair at all. I like the Chattacooootchie stone method. Sounds easier to me. Good Luck.:pray:

There are companies who do this if you are out of warranty. Ramjack comes to mind.

They basically drill holes in the slab and pump a slurry of fast setting mud/concrete in the void to lift it.

The question is however, would it be less expensive than just taking that small slab out and re-pouring it......?

When I lived in Virginia, I hired a company called Concrete Jack. They drilled dime-sized holes in the slab, and pumped a foam material under the slab and raised it. It was a very good solution, but I don't know if anybody does it here. There were other companies who offerred to tunnel under the slab and install a concrete jack.

I agree with Frank, probably cheaper to have slab removed and repaired if not covered by warranty. However, make sure whomever you get to do this knows this is a SMALL job as there is a minimum charge for concrete delivery.
