Waterproof Decking System: Keep Your Under-Deck Space Dry & Usable

Admin - 2026.04.23

Problem Solved
Elevated decks often waste the space underneath due to water leakage, moisture damage, and mold growth. Traditional solutions fail to provide lasting protection.

How It Works

  • Solid PVC construction(1-inch thick, no fillers) with ASA surface layer for weather and UV resistance.
  • Integrated sealing system– a vulcanized silicone gasket wraps around the tongue and compresses into the groove during installation, creating a continuous waterproof barrier.
  • Smart drainage designguides water along channels to the deck edges, preventing pooling or seepage.

Key Advantages
     Complete waterproof protection – keeps under-deck space fully dry
     Durable across extreme temperatures (-100°F to 400°F)
     Low maintenance, no rotting or warping
     Simple tongue-and-groove installation
