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.
