Description
Viper VaporCheck is a cross-woven under-slab vapor barrier featuring enhanced puncture and tear strength.
UNITS PER SKID:
Material Use:
Viper VaporCheck 10-mil is a high-performance, cross-woven polyethylene vapor barrier designed for under-slab applications. It is used to prevent moisture migration through concrete slabs-on-grade, thereby protecting interior flooring systems and moisture-sensitive furnishings. It also serves as a barrier against radon, methane, and other soil gases, and helps control condensation, mold, and mildew within the building envelope.
System Components:
Viper VaporCheck 10-mil is typically used as part of a comprehensive vapor barrier system that includes the following accessories for sealing and detailing:
- Viper Vapor Tape – for sealing overlaps and seams.
- Viper Double Bond Tape – for enhanced seam adhesion.
- Viper VaporPatch – for sealing around penetrations and repairs.
- VaporCheck Mastic – for sealing terminations and penetrations.
These components work together to create a monolithic, continuous vapor barrier beneath concrete slabs.
Applications:
This product is suitable for use in commercial, industrial, and residential construction projects where a high-strength, low-permeance vapor barrier is required beneath concrete slabs. It is ideal for:
- Slab-on-grade construction
- Areas with high moisture or gas migration risk
- Installations requiring protection from radon, methane, and other soil contaminants
- Projects with moisture-sensitive flooring systems
Application Details:
- Installation Surface: Place directly over a leveled and compacted granular base.
- Placement: Unroll with the longest dimension parallel to the direction of the concrete pour. Extend over footings and seal to foundation walls or grade beams.
- Seams and Penetrations: Overlap seams by a minimum of 6 inches and seal with Viper Vapor Tape or Double Bond Tape. Seal all penetrations (e.g., pipes, columns) with VaporPatch or VaporCheck Mastic.
- Protection: Avoid punctures during rebar placement and concrete pouring. Use bar supports directly on the membrane and avoid driving stakes through the barrier. If penetrated, repair with appropriate Viper sealing products.
- Cushion Layer: If a cushion or blotter layer is required, use washed rock to minimize damage risk.
Special Notes:
- Thickness: Nominal 10-mil (0.010 inches)
- Water Vapor Permeance: 0.0016 perms (ASTM E 96) – extremely low, exceeding ASTM E 1745 Class A requirements
- Puncture Resistance: Up to 15,839 grams (ASTM D 1709), 91.59 kg (ASTM E 154), and 76 lbs (ASTM D 5602)
- Tensile Strength: 136 lbf/in (MD), 134 lbf/in (TD)
- Operating Temperature Range: -70°F to 180°F
- UV Resistance: Not UV-stable – intended for sub-slab use only and should be protected from prolonged UV exposure
- Chemical Resistance: Unaffected by alkali salts, sulfates, and petroleum-contaminated soils
- Life Expectancy: Indefinite when installed correctly and protected from physical damage
- Maintenance: None required post-installation
Environmental Considerations:
Viper VaporCheck 10-mil contributes to healthier indoor environments by reducing the ingress of soil gases such as radon and methane. It is manufactured from prime virgin polyethylene and is resistant to chemical degradation, making it suitable for use in contaminated soils.
This material is a critical component in moisture control systems for concrete slab construction and should be installed in accordance with ASTM E 1643 and ACI 302.2R-06 guidelines.
