EZ-STIK is a concrete joint sealant. It is used primarily to seal manhole, septic tank, concrete pipe, elliptical pipe and box culvert joints. EZ-STIK is available in a wide variety of sizes to fit almost any precast joint and provides a seal with both adhesion and rebound, for long-term reliability

Features and Benefits

  • All-weather performance
  • Coated release paper for easy installation
  • Wide variety of sizes and styles
  • Cohesive properties allow for joint movement
  • Increased proportion of butyl rubber content

Typical Applications

  • Sanitary Manhole Joints
  • Stormwater Manhole Joints
  • Irrigation and Drainage Systems
  • Box Culverts
  • Elliptical/Arch Pipe
  • Architectural Foundations
  • Underground Utility Vaults
  • Stormwater Treatment Structures
  • Stormwater Inlet Structures
  • On-Site Treatment Tanks
  • Grease Interceptors
  • Wet Wells

This butyl sealant meets or exceeds:

  • ASTM C990 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

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.

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 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
