Hello,
I have a slab that pools water next to the house when it rains How can I fix this? Can I just lay some cement and build it up next to the house to keep the water away?

Well..................
If you drive over it, or live in a freezing climate-doubtful you can keep it from cracking and pealing off..................
But, I've had luck here in NW Oh fixing sunken sidewalks by building up (feathering) some concrete patch from zero to an inch.
It might work.
I begin by cleaning the concrete where I'm going to patch. You could acid wash it-which wouldn't hurt as it might get the vegetable matter out of the pores. Clean and rinse.
Next day, make sure the area you are going to work is still DAMP. No standing water. Paint on (roller or brush) Concrete Glue-you can find it with the patching concretes.
I use Sand Mix-the vinyl concrete patches dry too quick and for some reason-have failed after a winter or two. The bond just isn't there.
Quickcrete has some kind of "topper" that might work-never used it.
Mix up the sand mix and start with the thick area-You might want to lay down a sacrificial screed up against the wall-to keep your thickness consistant-after you get a section done-pull it out and fill in with the sand mix. Work the thin area (straight line if you can do it-it'll look better) with your trowell. You are going to have the hang of it by the time you get done.
I usually cover it with a wet towell and a pc of visqueen after it sets a bit. I keep it damp for a couple days. You could do it with old flannel sheets-or other.
The longer it takes to dry out the better. You skip either the concrete glue or this keeping it moist and you just wasted you time for sure.
or
Saw the slab and have someone that pumps up concrete come in and lift the side along the house.
Either way, finish it off with a neat healthy bead of Urethane Caulk at the house / slab juncture.
This may be best dealt with by slab jacking. I have no idea how much it would cost, but it might not be too bad.
Thanks,
I was thinking along the lines you mentioned. There is no vehicle traffic or freeze thaw cycle so it should work.
Thanks again,
Mike
Best of luck
But remember, my ramp up to a raised sidewalk section is small potatoes to what you are talking about.
Unless you're thinking the concrete mud jacking.
Mud jacking is the best choice.
