hoping to get some opinions on this.
I recently dug up a wall of my house as I was having water problems. It's been now sealed, backfilled, and I'm debating how to refinish the top layer. It used to be a poured concrete sidewalk, that ranged from 4" to 9" in thickness (They never levelled before pouring). THis sunk and sent water directly into my foundation wall.
My plan is to just put paving stones right now, but I was thinking about the layers immediately under the stones. My plan is to use about 3" of Granular B Gravel, then paversu on top of it. I also have extra 1" XPS insulation from a basement project. Have you ever heard of laying these boards along the sidewalk, sloped so that any water that gets through the pavers and gravel, gets immediately diverted away from the house? The sidewalk will be approximately 3' wide, so if this idea works, it will send water 3' away from the house, keeping my basement even more dry during the spring thaw and during heavy rain.
I'm trying to think of any reason this would be a problem. Only thing I could think of is perhaps if it doesn't drain away fast enough this could lead to pooling water, but that's quite a bit of water to do that.
Thoughts? Warnings? THanks.
