NOTE ** Although this guide specification is proprietary,
it does include reference and performance
standards. The specifier should edit this
specification to suit the project's requirements.
Selection of the appropriate product for the
project is the responsibility of the customer.
NOTE **
NOTE ** Concrete accessories (Waterstops) may be specified
in this section or in the Division 3 related
sections listed below.
PART 1 GENERAL
1.1 SECTION INCLUDES
NOTE ** Add other items below if required for project.
A. Swellable strip waterstop embedded continuously along
concrete contraction/control and non-moving construction
joints creating a continuous barrier to fluid migration.
1.2 REFERENCES
NOTE ** Delete references from the list below that are not
actually required by the text of the edited
section.
A. ASTM D 71 - Standard Test Method for Relative Density of
Solid Pitch and Asphalt (Displacement Method).
B. ASTM D 217 - Standard Test Methods for Cone Penetration
of Lubricating Grease.
1.3 DELIVERY, STORAGE AND HANDLING
A. Store waterstop in factory package to protect from oil,
dirt, and prolonged ultraviolet exposure.
B. Store materials under cover to protect from moisture
which may cause premature waterstop swelling.
PART 2 PRODUCTS
2.1 MANUFACTURER
A. Provide products manufactured by Greenstreak Plastic
Products Co., Inc., St. Louis, MO, 63122. ASD.

2.2 WATERSTOP MATERIAL
NOTE ** SWELLSTOP is a flexible coiled strip of swellable
clay and butyl rubber compound designed to swell
upon contact with water. The swelling action, when
confined in NON-MOVING concrete joints, creates a
long lasting compression seal. Provide a minimum 2
inches of normal weight concrete clear cover with
Swellstop to avoid potential concrete spalling.
SWELLSTOP is used for vertical and horizontal
reinforced concrete eight inches thick or greater
with two rows of reinforcement. Note that
SWELLSTOP is not a self-adhering product.
A. Swellable Strip Waterstops: Greenstreak "SWELLSTOP";
strips composed of bentonite and butyl rubber which
swells upon contact with water; one inch (25 mm) by 3/4
inch (19 mm) by 16 ft-8 inch (5078 mm) roll.
1. Properties:
a. Specific gravity in accordance with ASTM D 71:
1.2 minimum, 1.35 max.
b. Penetration in accordance with ASTM D 217 at 77
degrees F (25 degrees C): 50 minimum, 120
maximum at 150 GTL; 80 minimum at 300 GTL.
c. Penetration after 21 day aging in accordance with
ASTM D 217: 75 at 300 GTL at 130 degrees F (54
degrees C).
d. Unrestricted swell: Moisture gain of 200
percent, minimum, after 21 days.
e. Application temperature range: 5 to 125 degrees
F (-15 to 52 degrees C).
f. Service temperature range: -40 to 212 degrees F
(-40 to 100 degrees C).
B. Accessories:
1. Adhesive: "Swellstop Primer Adhesive"; solvent-
based, for securing waterstop to horizontal and
vertical substrates.
a. Concrete cut nails if required for securing waterstop
to vertical joint face.
PART 3 EXECUTION
3.1 INSTALLATION
A. Butt ends of strip coil. Press ends together to ensure
no separation and no air pockets.
B. Immediately prior to placing second pour, inspect
waterstop for premature swell, discontinuity, and debris
contamination. Replace swelled and damaged waterstop.
Remove unacceptable waterstop from site and dispose of
defective material in accordance with local regulations.
C. Adhere waterstop to concrete utilizing primer adhesive.
D. Allow primer adhesive to dry for two hours prior to
application of waterstop.
E. Apply waterstop the same day as adhesive.
F. Protect waterstop from moisture, dirt, oil, and sunlight
during progress of work.
G. Install waterstop with minimum 2 inches (50 mm) clear
cover to concrete face.
