Substrate & Assembly Details

Plazadek Floating System Substrate Recommendations

Substrate Requirements

The first step towards a completely waterproofed floating deck system is a properly prepared substrate. All Duradek vinyl options must be installed on a flat, smooth surface; including untreated plywood and concrete.

Some of the overlay options in floating deck systems can create a heavy dead-load. In these cases a consultant should verify the structure can accept the added weight.
