Flagstone patio - edging and joints
by Tony Vander Linden
I have a couple questions. I'm laying my first flagstone patio. I live in Austin, TX. It will be about a 400 sq ft patio with 2 inch flagstone. We really only have a day or two below freezing, so I'm planning a 2 inch base of decomposed granite and 1 inch of sand. I'll lay the flagstone, then border with a limestone block edging. I think I'll mortar the edging, then I won't need any reinforcement on the edging right? Should I mortar the cracks of my flagstone patio or just use sand?
Thanks for any advice you can give. Love your website!
