-
- 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.
