Question

What should the slope away from a foundation be? How many inch drop in how many feet?

Answer 1

Hey , first guy I ever heard ask...........good man......Pumbers pipes are 1/4'' per foot.....so 32' would be 8''. I don't like to see it too great but that no. would be min. imo........but do get run away from your house......good luck.

Answer 2

You don't want rain that falls near the house to flow towards the house.  Water against the foundation is not recommended, especially in moister climates where subsurface moisture may be such a problem it gets into the basement or crawl space.  

1:12 is fine
