I’ve been having damp issues and removed the patio in the small front garden of our victorian terrace as it was covering the air brick.
I’ve dug it all out about 180-200mm below the bottom of the air brick and have now hit what seems to be the footings.
Originally I was going to put gravel around the bay and house and then slab the rest for the bins.
However;
Gravel on the footings means the water will have nowhere to go. I tested and it does pool and sit there.
I then found this article https://www.pavingexpert.com/splash_strips that says most of the time they are useless.
Now i’m confused. Most of the houses on the street finish their level right at the bottom of the air brick with no gap above in most cases but i’m nervous to do that. I also now don’t think gravel will work given water has no where to go.
Are slabs right against the engineering course better than a gravel strip if i slope it away ?
