What kind of decking lasts the longest?

The type of decking material that lasts the longest is composite decking, made from a mixture of wood and synthetic materials. Composite decking usually is composed of roughly 50% recycled wood fibers, such as sawdust or wood chips, combined with about 40-50% polyethylene (or similar plastic) and 10-15% bonding resins and additives.

Composite decking is highly resistant to moisture and insects and is more durable than traditional wood decking. This type of decking will last up to 25-30 years with proper maintenance.
