I want to create look of giant poured in place pavers on my driveway, using the existing concrete slab. Other than cutting all the way thru the slab and removing giant lines of concrete, then refilling it to desired depth, is there an easier way to do this? I want 3-4” grooves between pavers for that fake turf grass. Don’t think I need more than 1” depth for that. My question is: is there a tool or grinder blade that can cut a wide, shallow channel in concrete that DOESN’T have to be chipped out?
