TPE Expansion Joint Tape

High-Performance Flexible Joint & Crack Waterproofing System

  • Excellent crack- and joint-bridging capability
  • Excellent resistance to UV
Expansion Joint Tape joint and crack sealing system for construction joints in New Zealand

Product Overview

The TPE Expansion Joint Sealing System is a versatile, high-performance sealing solution designed for waterproofing construction joints, movement (expansion) joints, connection joints, and structural cracks in demanding construction and civil engineering applications.

The system allows high and variable levels of movement in one or more directions while maintaining a continuous, watertight seal. It consists of a flexible TPE-based waterproofing tape with excellent elongation and durability, bonded to the substrate using compatible structural adhesives or resin systems depending on application requirements.

The sealing tape is thin yet highly robust, offering exceptional crack-bridging capability and long-term performance in aggressive environments. Heat-weldable overlaps ensure secure, watertight continuity across joints and transitions.

Frequently Asked Questions about Expansion Joint Tape

What makes this system suitable for movement joints?

The TPE tape has high longitudinal and lateral elongation, allowing it to absorb structural movement without tearing or losing watertightness.

Can it be used on cracks as well as joints?

Yes. The system is suitable for sealing both static and dynamic cracks, as well as construction and expansion joints.

Is the system suitable for underground and water-retaining structures?

Yes. It is commonly used in basements, tunnels, reservoirs, swimming pools, and wastewater facilities.

How are joints connected?

Tape overlaps are sealed using hot air welding, creating a secure, continuous waterproof joint.

Can it be used with drinking water structures?

Yes. The system is plasticiser-free and suitable for applications involving potable water.
