# patio of sand, rock, stone

• posted on May 26, 2004, 2:19 am

I'm building a natural stone patio. I'm inexperienced landscaping, and have run into a big problem:
Problem: I put in 4 ton of "#4 Dust Crushed Gravel", but the landscaper says that I misunderstood them, and that I now have to take out the dust crushed gravel and put in 5/8 rock instead, for drainage.
Description: It's a 25' X 5' area, 7" deep. One long side is against the house. (to see the ascii figure below, use constant width font)
Solution? (by me): Keeping as much of the dust crushed gravel as possible, make a "canal" in the dust crushed gravel 5" deep and 3 feet wide. Fill it with 5/8 rock. Cover with sand.
In any case: In the effort to keep water from soaking against the foundation shouldn't I keep the "5/8" rock drain" area away from the foundation? In other words, does the drainage into a 5/8" rock fill bed (substrate) trap water against the house, underneath the surface?
I'm not experienced landscaping. Is my solution good enough for you?

Thanks for looking.

Sounds totally sensible to me. If the landscaper doesn't understand that water runs downhill and water is not good around a foundation then find a more competent group to work with. Good luck.
