- High-Efficiency Waterproofing, Create a Dry Space Deckit HDPE drainage system keeps the area under pergolas/2nd-floor patios dry in rainy weather, diverts water flow, seals out moisture and solves water leakage problems from the root.
- 20MIL HDPE Material, Durable & Weather-Resistant Crafted from 20MIL(0.5mm) high-density polyethylene, it is tear, corrosion, UV and aging resistant. Flexible and bendable, it fits the curves of elevated decks and is durable in all weather conditions.
- 16" Joist Spacing Fit, Invisible & Sleek Design No obtrusive exposed parts, precisely adapted to 16" joist spacing. The 16FT single roll is easy to cut and splice, suitable for small to medium-sized pergola and patio projects.
- 3-Step Quick Installation 3 simple steps: install downspouts → lay the membrane roll → seal the joints. No professional tools required, easily build a neat, custom under deck drainage system and save construction time.
- Extend Service Life, Reduce Maintenance Costs Prevents water and moisture erosion, protects the deck substructure from wood rot, preserves product quality and drastically cuts long-term maintenance expenses.
