Stone terrace - house joint leaking

Hi,

We purchased a home which has a concrete/stone terrace attached to the exterior brick wall. The joint between the terrace and the house is leaking and water is running down the house wall. This makes the house wall under the terrace wet (inside the house).

There is no drainage on the terrace and it seems to be level (not sloped away from the house). Also, since this is the Northern side of the house, it's cooler and snow seems to be accommodating in that area (judging by images, our first winter there would be next year).

It looks like there is some code that says permanent stone terrace cannot be attached to the house, so there is an inch gap between them filled with some sort of foam (I'm not sure exactly).

Question is what's the best way to waterproof this terrace-house joint or otherwise prevent the water from accumulating in that area and going down.

Thanks a lot,
Mike

Welcome to the forums.

We try to keep a topic in a single thread so this is the thread that will be active. The other one has been removed. This is a good place for your thread and it will be seen and responded to.

A picture of the joint/area between the terrace and the house would be helpful too.

Thanks PJ

For some reason it fails when I upload the second image, so here is a link to it where the joint can be seen. Thanks....

cleanout what's in there now & install some closed-cell backer rod larger than the joint you're trying to seal,,, then caulk w/NP1 (vertical grade) & 'tool' it properly,,, the w/site has the info you need

No drain and not graded away from the house? What happens when it rains? Yes you need to clean the area and apply a flexible sealant but it will only be a short term fix if water continues to accumulate there. You should install a drain or cut a drain path away from that corner.

Like this

You can cut the stone with an angle grinder then grade the cuts away from the house. Then seal with with an elastomer paint or clear coat

Pictures can be deceiving and it may just be an effect of the dirtiness but it looks a bit like the terrace slopes towards there
