Waterproof thermally modified Cypress decking We start with real American Bald Cypress — naturally resistant to moisture and termites. Then we kick it up a few notches. Our thermal process uses just heat and steam to toughen every board from the inside out. No chemicals. No glue. No toxins. Rain? Humidity? Bugs? This wood doesn’t blink. It won’t cup. It won’t swell. And termites — there’s nothing here for them to eat. Great for concrete patios, porches, docks, pool decks and anywhere the elements try to win. SOLD BY THE LINEAR FOOTPricing shown is based on 6" wide decking.Quantity entered = total linear feet needed.Example: Quantity 100 = 100 linear feet of decking, NOT 100 individual boards. Priced with grooved edges. Shipping: Our boards range from 4' to 12′–16′ in length, and many carriers inside Shopify cannot ship lumber over 8 feet. If your order contains long lengths, checkout may not generate a freight price.
