Hi,
I have a drainage issue which is causing damp within my home,
Please have a look at the pics, its been raining today and you can see water forming puddles around the building. You can also see water which is channeled around the bay window (as it is on a slope) but as it goes passed the cut off airbricks it drains through onto the subfloor. As you can see we have a puddle under the floor today after a couple of hours rain.
Two air bricks on this side of the building either side of the bay window. These are two brick's deep and what looks like an original doc is level with the top of the air bricks. Pointing has mostly gone at ground level.
I'm thinking of removing the last course of bricks on the driveway and installing a concrete channel (so ground level would be 2 air bricks below the dpc where it meet's the houses) which would drain into existing drains. I woudl repoint the brick work as well, my questions are:
1) Am I on the right track?
2) How am far should I dig down and backfill with concrete?
3) I think the house is lime mortar (1929), should I repoint in lime? If I'm pouring concrete do I need to repoint below the level of the concrete? If so how long should I wait for the pointing to dry before installing the concrete?
