Remove the existing turf by hand or a turf cutter. You can rent one at a home improvement shop. Mark the surface where you want to install the EnviroTurf by hammering timber stakes around it. The stakes should protrude from the ground by 3 inches.
Lay a 3-inch-high layer of crushed stone on the treated surface. Compact the crushed stone with a tamper, which you can also rent from a local home improvement shop.
Infill the area treated with infill or crushed sand. Level the ground with a rake, then compact the ground with a lawn roller.
Apply a weed membrane on top of the sand to prevent any weeds from growing through it. Cut the membrane to the dimensions of your lawn with a carpet knife. Nail it to the stakes using 1-inch galvanized nails.
Lay EnviroTurf on the area in the direction you prefer, taking care to overlap the pieces. Overlap the stakes by a few inches, and nail the edges to the ground with 1-inch galvanized nails.
