Repair gap between external wall and concrete slab

Post by udaman »

Hi

There are some areas around my house where there's a gap between the concrete slab/path and wall. In at least one place the water is getting in enough to make the wall wet inside the house.

What's the best stuff to use to fill the gaps?

Should I look to fill the gap with on product, and then put in an angle section of concrete to add a second layer of protection and to direct water away?

If I should be using concrete or mortar for the repairs, what mix should I use?

Or am I barking up the wrong tree completely?

Any advice much appreciated.

Cheers

Pictures would help, pictures of the offending area would be even better.

Would you hit a nail with a shoe because you don't have a hammer? of course not, then why work on anything electrical without a means of testing Click Here to buy a "tester" just because it works, does NOT mean it is safe.

Good weather and a BH weekend, so hoping to get something done with this this weekend...

If nothing else, I was thinking to remove the existing knackered fillet, repair obvious cracks and defects in the ground-wall join with a concrete repair mastic, followed by a new fillet. I figured and hoped that if this worked in the past hopefully it will again.

I've no idea what mix of cement to use, whether to use SBR, etc. - so any thoughts on that would be great.

And any other thoughts most welcomed too.

Many thanks
