With a few bags of pre-mixed concrete, you can enjoy a block style pathway. The 2' x 2' recycled plastic forms are in the shape of stones or bricks. Simply ready the ground by removing approximately 1" of soil, fill the cavities of the Pathmate with wet concrete, and trowel the surface smooth. After about one minute, the mold can be moved to the next spot. Each section makes 4 square feet, is 1 3/4" deep, and uses one 80-lb bag of concrete.
