VaporStop Moisture Barrier
VaporStop™
Moisture Barrier
VaporStop™ System
The VaporStop™ membrane system is a high-
performance, polyethylene barrier designed to resist
moisture migration through concrete slab-on-grade. The
membrane is a field-tested and cost-effective method of
controlling moisture transmission in enclosed structures.
The VaporStop™ membrane, available in 2 thicknesses,
protect the flooring, finishes and furnishings in
completed structures from moisture infiltration damage.
A membrane also reduces condensation, mildew and
mold, while improving indoor air quality.
The VaporStop™ membrane meets or exceeds the
“Standard Specification for Water Vapor Retarders Used
in Contact with Soil or Granular Fill Under Concrete
Slabs” (ASTM E-1745). The VaporStop membrane
is designed to meet or exceed the Class A, B and C
performance.
Description
VaporStop™ is a high-performance membrane barrier used in residential and commercial projects. It is
designed for use under concrete slabs, in crawl spaces and foundation walls. It controls moisture transmission
within the building interior by preventing water vapor from permeating the concrete. It greatly reduces
condensation and mold formation, protecting flooring, finishes and furnishings.
Features
•
Reduces damaging moisture migration
•
Extremely low moisture vapor permeability
•
Outstanding tear resistance
•
Exceptional impact strength
•
Resists attack by organisms in contacting soil
Material
VaporStop™ is an ASTM-Certified Class A made in the USA vapor barrier made from high performance
polyethylene film using high quality prime, virgin resins. VaporStop™ is designed as a low permeance, high
strength, and puncture resistant film that meets and exceeds the ASTM E1745 requirements for a Class A
vapor retarder. Standard nominal 10 mil in green and 15 mil in green.
In a structure without membrane protection, research
has found that 80% of the moisture within the building
originates from site ground water. (HUD Research)
VaporStop™ Physical Properties
Nominal Thickness 10 mil 15 mil
The VaporStop™ membrane, when properly installed (refer to back
page), will provide an effective and economical method for limiting
water vapor transmission through a concrete slab-on-grade.
The VaporStop Tape is a polyethylene film with pressure-sensitive
adhesive, specifically designed to bond and seal the VaporStop
membrane system.
VaporStop Tape is meets or exceeds the “Standard Practice for
Installation of Water Vapor Retarders Used in Contact with Soil or
Granular Fill under Concrete Slabs” (ASTM E-1643).

VaporStop™ Installation
1. Consult local building codes and any specific instructions on the project drawings before installation. Do
not proceed until site conditions are acceptable and approved. Installation must comply with all applicable
local, state and federal code jurisdictions. Any unacceptable conditions must be corrected before
installation.
2. Level and tamp/roll the granular base as specified by the project drawings. If sharp, crushed rock is used,
then a layer of 1/2” fine grade compactible fill is required between the base and the VaporStop membrane
to prevent tears and punctures.
3. Unroll the VaporStop membrane with the longest dimension parallel to the direction of the planned concrete
placement. For a typical floor slab, lay the VaporStop membrane over the granular base and footing,
stopping at the wall and sealing the end with VaporStop Tape.
4. The VaporStop membrane should completely cover the granular base in the planned concrete placement
area. All joints/seams should have a 6” overlap secured with VaporStop Tape. Keep joints/seams free from
dust, dirt and moisture for maximum adhesion of the pressure-sensitive VaporStop Tape.
5. Repair any tears or punctures with a VaporStop membrane patch that has a 6” overlap in all directions and
securely tape the entire patch perimeter. Keep patch area free from dust, dirt and moisture for maximum
adhesion of the pressure-sensitive VaporStop Tape.
6. Use only brick-type or plate-type bar supports to protect the VaporStop membrane from puncture. Do not
drive forming stakes through the VaporStop membrane.
7. All pipes, ducts or other penetrations through the VaporStop membrane must be properly sealed. Boots
can be fabricated from the VaporStop material and sealed with VaporStop Tape. Cut the size and shape
necessary to form a tight-fitting seal around each penetration and seal all the edges with VaporStop Tape.
8. When placing concrete on the VaporStop membrane in hot weather, use a wet curing blanket to prevent the
concrete from shrinking, curling or cracking as a result of rapid surface drying.
9. Contact your SureBuilt representative for technical assistance and recommendations for usual applications
or conditions.
Storage
Store products in original, unopened, undamaged containers
with identification labels intact. Protect material from exposure
to ultraviolet light, excessive moisture and excessive heat.
