Viper II Platinum is an under-slab vapor retarder designed to stop moisture migration through concrete slabs-on-grade. It's built for commercial, industrial, and residential applications—and yes, it’s the moisture barrier you didn’t know you needed until you did.

Key Features & Design

• Size & thickness: 14 ft x 210 ft x 8 mils
• Material & construction: Manufactured using seven-layer co-extrusion technology from virgin resin
• ASTM E 1745 Class A compliance: Exceeds ASTM E 1745 “Class A” guidelines for blown films under 10-mils thick
• Moisture control: Reduces water vapor emission transfer and moisture migration from entering the building envelope on commercial, industrial and residential applications
• Durability: Maintains long-term performance after exposure to adverse soil condition; high puncture and tensile strength
• Interior protection: Controls condensation, mold, mildew, degradation and prevents costly flooring failures and damage to moisture sensitive furnishings
• Radon & gas migration: May be used to reduce radon and methane gas migration and is resistant to other adverse soil conditions

Trusted performance for modern building envelopes, Viper II Platinum delivers reliable moisture protection without the drama. If moisture migration is the problem, this barrier has you covered—with seven-layer resilience and a Class A seal of approval.
