new slab of concrete over existing


Hi Everyone,

The screened patio that i currently have is a pain. The leveling is not perfect and the water drains to one spot and sits in the corner. What I would like to do is pour a new slab which is even with the framing of the screen and also has a pitch of a degree or two so the water drains away from the house and and right out of the screen area. Any ideas??? Thanks

you could pour a self leveling floor over your slab. there are companies that specialize in this. Its mainly used for radiant heated floors. but could be used for your task. I have used this process for basement floors with no problems. BOB

If you're going to go through the trouble of pouring a new slab, you may as well just jackhammer out the one that is there and start new. The slab should drop an inch or so every foot (that's just a guess, do your research first) away from the house (everything should be graded away from the house, shouldn't it?).

Huh?

I don't think so. Check it out.

there is a method you can use to fill the bird bath - polymer-modified cement concrete works great - we do it all the time using a 6" sched 80 pipe for a screed - 1/4" per ft works !

See, I KNEW I wasn't correct. An inch every 4 feet. Now I remember.

That's why I just drive the truck. This stuff is done waaayyyy after I leave.

I thought that sounded kinda steep!
