But before you do, use this guide to find the best alternative to the boring and bland pressure treated deck.

A truly unique product indeed, BamDeck is a bamboo composite decking material. But you may be asking "isn't bamboo a wood"? No, bamboo is a grass that grows very quickly and nearly anywhere in the world.

Vinyl comes in a wide variety of colors and shades to create any design or pattern your heart desires. It can be attached easily to conventional framing members or composite materials with ease. Surface penetrations from screw holes tend to seal tight after time, helping to prevent decay of decking fasteners.
