Technology and Design

What is Eovations™ Technology?

Since its creation in 2007, Eovations™ technology has perfected the substrate found in composite decking.

This unique process starts with a mixture of polypropylene and calcium carbonate that’s pull extruded for cavitation. Cavitation creates tiny air pockets that keep the boards lightweight, but with a fiber-like structure similar to wood, giving it unmatched strength.
