GratedeX from deXstone is Kaufmann's choice for achieving a stone deck above grade. The system—comprised of a fiberglass underlayment that's installed over traditional wood framing—uses stainless steel fasteners and adhesive to accept natural stone or tile. Its 16-inch stones are installed with an 1/8-inch joint spacing to promote water drainage. deXstone, 503.439.8872; www.dexstone.com.
