What are Viper II Under-Slab Vapor Barriers?
Viper II products, by ISI Building Products, are multi-layer (co-extruded), virgin polyolefin under-slab vapor barriers/retarders. What makes Vapor II Under-Slab Vapor Barriers incredibly effective is the virgin resin which contributes to its long-term stability and prevents the material from breaking down when buried below the slab.
Engineered with Quality – Viper II Under-Slab Vapor Barriers
Your professional building team can rest assured, Viper II Under-Slab Vapor Barriers are engineered with quality, providing resistance against punctures, tears and water vapor. The high puncture resistance and tensile strength reduces potential damage when exposed to tough construction environments. Notably, Viper II Under-Slab Vapor Barriers have low water vapor permeance properties which are instrumental to preventing water vapor migration.
An Industry Standard for Under-Slab Vapor Barriers and Retarders
Viper II products are tested and engineered to meet and exceed the Class A, B and C requirements outlined in ASTM E 1745 (Standard Specification for Plastic Water Vapor Retarders Used in Contact with Soil or Granular Fill under Concrete Slabs). ASTM E 1745 is the widely recognized industry standard for under-slab vapor barrier/retarders.
What Sizes are Available? – Viper II Under-Slab Vapor Barriers
Viper II Under-Slab Vapor Barriers are available in a range of sizes including 15 Mil. – Class A, 10 Mil. – Class A, 10 Mil. – Class C and 6 Mil. – Class C.
- High strength polyolefin based under-slab vapor retarder specifically designed for preventing moisture migration through concrete slabs-on-grade.
- Reduces water vapor emission transfer and moisture migration from entering the building envelope on commercial, industrial and residential applications.
- Controls condensation, mold, mildew, degradation and prevents costly flooring failures and damage to moisture sensitive furnishings within a building’s interior.
- May be used to reduce radon and methane gas migration and is resistant to other adverse soil conditions.
15 Mil. – Class A – Viper II Under Slab Vapor Barriers
10 Mil. – Class A – Viper II Under Slab Vapor Barriers
10 Mil. – Class C – Viper II Under Slab Vapor Barriers
6 Mil. – Class C – Viper II Under Slab Vapor Barriers
Installation Instructions for Viper II Under Slab Vapor Barriers – Provided by the Manufacturer – ISI Building Products
Note: The following installation instructions are based off of ASTM E 1643 (Standard Practice for Installation of Water Vapor Retarders Used in Contact with Earth or Granular Fill Under Concrete Slabs).
1. Install Viper Vapor Barrier over compacted base material. Viper Vapor Barriers are designed to withstand rugged construction environments; therefore it is not necessary to have a perfectly smooth subsurface.
2. Unroll Viper Vapor Barrier with the longest dimension parallel with the direction of the concrete pour. The Viper Vapor Barrier should completely cover the entire pour area.
3. Extend Viper Vapor Barrier over footings and seal to foundation wall, grade beam, or slab at an elevation consistent with the top of the slab or terminate at impediments such as water stops or dowels. (Refer to slab on grade detail).
4. All joints and seams should be overlapped a minimum 6 inches and sealed with 4 inch White Polyethylene Viper Vapor Tape and/or 2 inch Viper Double Bond Tape. (Note: The area of adhesion should be free from dust, dirt and moisture to allow for maximum adhesion of the tape).
5. All penetrations such as utilities and columns should be sealed using Viper Vapor Barrier, Viper VaporPatch and/or VaporCheck Mastic. Doing so creates a monolithic membrane between the surface of the slab and moisture sources below the slab. (Refer to Boot and Patch Details).
6. If Viper Vapor Barrier becomes damaged during or after installation, repairs must be made. Methods of repair include:
A. Create patch using roll of Viper VaporPatch. Peel off release backing and adhere over damaged area (Refer to Boot and Patch Details).
B. Cut a piece of Viper Vapor Barrier large enough to extend 6 inches beyond damaged area on all sides.
Secure patch with either 4 inch White Polyethylene Viper Vapor Tape and/or 2 inch Viper Double Bond Tape.
(Note: The area of adhesion should be free from dust, dirt and moisture to allow for maximum adhesion of the tape).
7. A secondary protective layer, such as fine washed gravel or sand is not necessary. If used, do so in accordance with American Concrete Institute’s ACI 302 guidelines.

What is the CSI (Construction Specifications Institute) Masterformat??
- The CSI MasterFormat is a coding system for document organization for construction related documents including construction design specifications, contracts, construction documents and other materials.
- The CSI uses specific numbers and titles that make up a universal indexing system.
- MasterFormat is also a publication created and maintained by the Construction Specification Institute (CSI) and Construction Specifications Canada (CSC). Notably, the CSI is widely used in the construction and operation of buildings and systems in many industries and projects, from healthcare and public infrastructure to educational structures and commercial. residential construction.
- Advantages of Using CSI’s MasterFormat:
- Improved communication between project groups, by for example, the design and construction teams. CSI allows all team members to refer to specific sections of any document using the universal coding system. This facilitates coordination and communication between project owners, architects, contractors, and suppliers, minimizing the time spent organizing documents.
For industries with complex operations, such as health care, MasterFormat helps communicate and organize critical operational information among designers, builders, operations managers, and facility owners. In addition, as these and many other industries are increasingly using building information modeling, or BIM, MasterFormat can be used by modeling software to enhance data interoperability and improve BIM adoption.
