Hey guys i am planning on installing a bluestone gravel driveway. I dont want weeds or would like to keep them at a minimum. The driveway is 15ft wide by 150ft long. I was thinking i could roll out some type of rotproof plastic or a tarp and then cover it with 4-5 inches of bluestone? I cannot find a underlayment product that i am asking for. All the tarps i found are rotproof but thats above grade. Any help is appreciated. Thanks guys.:thumbsup:
