Concrete Leveling Question

[Brad P.]

Property we closed on last week has a raised concrete patio going into the front door. Concrete is in good condition, no cracks or spalling, but there is a sag in the middle which leads to standing water every time it rains.

What's the proper way to fix this? I've read a bunch of different things from "use a concrete leveling agent", "concrete leveling agents are crap", "overlay the existing concrete with a thin layer of new concrete", "NEVER overlay concrete on existing concrete", etc.

All we want to do is make the patio level to get rid of the standing water issue.

There are some good overlay products that you can certainly level with. My dad has been doing overlays for a long time, so I know the industry as well. The only bad thing is that if you overlay and build up that area, you will need to overlay everything or else you will have unmatched concrete.

If the pad is just sunk, then mudjacking will be the way to go.

If it is a dip in the middle of a pad then I would def overlay. Don't use any product that contains epoxy. A lot of companies put epoxy in outdoor overlay products and it just does not hold up. When moisture gets pulled through concrete as it breaths it will eventually cause the epoxy to fail (epoxy & moisture = oil & water).

Hope this helps. If you want to know more pm me and I can try to answer any questions.
