1 PREFORMED BUTYL JOINT SEALANT Where To Use Sanitary Manhole Joints Stormwater Manhole Joints Irrigation and Drainage Systems Box Culverts Elliptical/Arch Pipe Architectural Foundations Underground Utility Vaults Stormwater Treatment & Inlet Structures On-Site Treatment Tanks Grease Interceptors Wet Wells What It Is Pro-Stik butyl joint sealant is a rope form joint sealant that will not shrink, crack or dry out. Containing a higher proportion of butyl rubber over competitive products gives you the added benefit of a better performing joint sealant. It provides excellent adhesion and cohesion to a wide-variety of surfaces such as concrete, metal, painted surfaces and even glass. How It Works Sealant is applied as a continuous ring around entire joint. The excess sealant is then cut to length to create a butt joint. Ends of butt joint are kneaded together. Protective release paper is removed from the sealant ring. Why It s Better Better all-weather performance. Low moisture vapor transmission rate (MVTR). Excellent adhesion to a wide-range of surfaces. Long service life. A variety of shapes and sizes to fit almost any application. Allow for joint movement while maintaining sealing properties. 112

2 SUBMITTAL SPECIFICATIONS The joints and/or joint surfaces of the structures shall be sealed with a butyl-rubber-based preformed flexible sealant conforming to ASTM C 990, paragraph 6.2. The material shall be or EZ-STIK as supplied by, Fort Wayne, Indiana, or approved equal. The butyl material shall consists of 50% (min.) butyl rubber and shall contain 2% or less volatile matter. For preformed joint sealants, the sealant shall be sized such that the joint is filled to 50% (min.) of its annular volume when fully assembled, and the sealant shall have the ends kneaded together at the overlap. Primer and/or adhesive Product Performance as recommended by the sealant supplier shall be employed for adverse, critical, or other applications. Testing of joints and compliance with construction requirements shall be conducted in strict conformance with the requirements of the sealant supplier. Pro-Stik Butyl Joint Sealant meets or exceeds all requirements of the following Standards, Specifications and/ or Test Methods: ASTM C Standard Specification for Joints for Concrete Pipe, Manholes, and Precast Box Sections Using Preformed Flexible Joint Sealants; Section 6.2 Butyl Rubber Sealants AASHTO M Joints for Circular Concrete Sewer and Culvert Pipe Using Flexible Watertight Gaskets ASTM C (2011) - Standard Test Method for Compression-Recovery of Tape Sealant ASTM C (2015) - Standard Test Method for Low-Temperature Flexibility of Preformed Tape Sealants 113

5 & EZ-STIK INSTALLATION INSTRUCTIONS 1. Dry joint surface if wet. (Joint surface must be dry.) 2. Clean all dirt, sand, mud, etc. from joint. 3. Remove roll from carton. (Keep away from dirt, etc.) 4. Place exposed surface down/ place against vertical surface/ press against concrete. 5. Apply sealant in continuous ring around the joint (DO NOT STRETCH!) 6. To complete sealant ring cutt off excess sealant with knife or sharp object. 7. Cut sealant so that when cut, the ends form a butt joint. (DO NOT OVERLAP!) 8. Knead the ends together to finish sealant ring. 9. Remove protective release paper from the sealant ring. 10. Assemble the joint. Align structure section as straight as possible for proper entry of the tongue into the receiving groove and home the structure section. When the structure section is correctly joined, and a compression pressure obtained, and EZ STIK butyl sealants will flow into a solid-pack and uniformly fill the annular space between the tongue and groove. TIP: 116 EZ #4 Primer can be used to improve sealant adhesion to the joint. When using primer, allow the primer to dry before placing sealant.
