I have an uncovered patio made of cement?

Question

it leaks into the room below it when it rains is there something to seal it or do i need to remove it and re do it

Answer 1

Sounds like u have a patio on top of ur room.  The moisture, might be coming in from the sides.  How bad is the leak?  Look around the sides...make sure it's properly sealed.  Create a ledge to guide the water OFF the walls.  Water penetration usually occured when there is a crack on the cement.  But at a seepage rate.  It's ur call....U can just seal the cement or u can make a new one.  It's a $ issue.  If I inspect the roof/ patio and it just call for a 1" layer to add on.  I would recomment that first.  Unless, u want to spent money like couple of thousand to satisfy urself.   Besides a good roofer will seal the patio with Hot mop and roofing rolls. At a fraction of cost.

This a case where a picture is worth a thousand words.

It sounds as if the slab is poured against foundation wall.A couple things to look at.

1) window wells set to low.

2) take a level and check slab and see if it drains away from house.A 1/4 to 1/2 bubble downslope should drain fine.

3) did they use expansion joint between slab and wall?.If they did you can use some self levelling caulk available at home depot/Lowe's.Small tubes run about $6.00 and the larger ones about $12.00.This stuff is extremely runny and self levelling,so keep a piece of cardboard close as not to get all over.

4) check other areas of backfill around house,could be coming from somewhere else.

Good Luck

Answer 3

Remove and redo.

Or find a builder who can seal it up somehow.

Answer 4

A seal job lasts about 3 years and a new pour with drainage will be more. Check you home owners insurance.
