Defy the storm with the strongest and only composite deck boards in the industry that can be installed in the ground, on the ground or underwater without any structural performance issues. At the foundation of every board is our proprietary Solid Core — an impermeable barrier that fights damage from moisture, rot, insects and other harmful elements. Our core maintains its integrity even after ripping and cutting, mitigating warranty issues and long-term damage. The result is a long lasting, low maintenance decking material specially engineered to last for years to come.
