I have a walkway that runs 16 inches parallel to my foundation along the entire side of my house. The walkway elevation is also higher than the top of the foundation where it meets the brick. This has created a drainage issue with water penetrating my foundation. Since brick is porous, I cannot grade the soil above the foundation line.
I think a drainage system would be best, but I was looking for direction given several constraints I've ran into.
Towards my back yard is a concrete patio at the same elevation as the walkway so I can't divert to the back without cutting a lot of concrete.
Towards my front yard looks to be at a slightly higher elevation than where the water is pooling unless I go out to the parkway. I'm not sure the city would allow this.
The space between my house and the neighbor's is less than 20 feet which I own most of. I was thinking of a dry well between the houses, but I'm not sure if it's far enough away from both of our houses (less than 10' from each house).
So I'm not confident about where to divert the water without causing unforseen issues or if I'm totally overlooking other options. My preliminary idea is to do several surface level intake drains, use solid PVC pipe, run it under the walkway into a dry well between the houses.
