Concrete Cracked and Not level

by Jon
(Longmont, CO)

I have a concrete slab that I want to put a Flagstone Patio on top of it. I have noticed that the concrete has a large crack in the middle that was caused when a portion of the concrete settled. Now, the settled part slants towards the house. Can I just add concrete to the current concrete to give the slab the desired slant? Will creating different thicknesses in the concrete cause problems with the hardening of the concrete? Thanks.

Thanks, David, for your comments. As I am pulling the wood off from the deck, I am also discovering that some areas have cement there, while other areas have little or no cement. Very interesting layout. I think the people who put in the deck were trying to cover up the mess underneath.

Dear Jon,

You can add more cement before you lay your stone. My dad does that many times.

You'll want to put in a metal lathe to tie in the old concrete to the new concrete. That will help stabilize the whole pad and help cracking in the future.

Great luck!
