I am installing some Pavestone Edgestones http://www.pavestone.com/retail/edging-edgestone.html as bed edging and tree rings for a customer. Is it necessary to use sand at the base of the stone or can I get by with just using native clay soils? We've got about 1/3 of it installed and it looks really good. And we're getting the base fairly well compacted by using gloves to hold the stones and banging them repeatedly into the bottom of the installation trench we dug out.
Is sand necessary here? If so, why?
Thanks
