What layers of gravel/sand would I use for a patio?
I haven't completely decided on what type of stone (flagstone vs. pavers) I want to use for our patio, so I'd be interested in hearing the answer for both.
What I'd like to know is what layers of material should I put down?
Should I use pea gravel for the base layer? Or is some cheap, crushed gravel fine?
Do I need sand on top of that gravel?
Just curious what the best combination of layers would be. For what it's worth, I'm in the Denver area.
