GeoDeck™ offers more than just beauty. Its patented formulation is, in part, what makes it a step above the competition. With a combination of Biodac®, rice hulls, high-density polyethylene resins, and other high-quality ingredients, GeoDeck™ has high fade resistance and very minimal water absorption in comparison to its wood composite competitors. Its strong I-Beam construction creates a stronger deck board than the competition even though it is lighter in weight and won’t rot or mold.
