Containing a higher proportion of butyl rubber over non-rubber bitumen and butyl, bitumen blended materials; EZ-Stik provides a better performing joint sealant for longer service life.

EZ-Stik comes in many sizes and shapes for sealing both precision and non-precision joints in manhole, catch basins, curb inlets, vaults, pipe, box culverts and other sanitary and drainage products.

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

  • Long service life.
  • A variety of shapes and sizes to fit almost any application.
  • Allow for joint movement and differential settlement while maintaining sealing properties.
  • Tested to higher standards than bitumen (mastic) and blended materials besides ASTM C990, Section 6.2 Butyl Rubber Sealants.
  • Compression Recovery – ASTM C 972-00 (2011): Butyl sealants provide rebound for joint settlement and movement.
  • Butyl rubber seals both precision and non-precision joints better.

  • Wet Wells

Meets or Exceeds

EZ-STIK BUTYL JOINT SEALANT meets or exceeds all requirements of the following Standards, Specifications and/or Test Methods:

  • ASTM C 990 – 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 198 – Joints for Circular Concrete Sewer and Culvert Pipe Using Flexible Watertight Gaskets
  • ASTM C 972 – 00(2011) – Standard Test Method for Compression-Recovery of Tape Sealant
  • ASTM C 765 – 97(2015) – Standard Test Method for Low-Temperature Flexibility of Preformed Tape Sealants

The joints and/or joint surfaces of the structures shall be sealed with a butyl-rubber-based preformed flexible sealant conforming to ASTM C990, paragraph 6.2. The material shall be PRO-STIK or EZ-STIK as supplied by PRESS-SEAL CORPORATION, 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 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.

  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 cut 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, PRO-STIK and EZ STIK butyl sealants will flow into a solid-pack and uniformly fill the annular space between the tongue and groove
