Product Description

Expansion seals or expansion joints as they are also known, provide a subtle yet crucial function in a wide variety of construction applications. The key purpose of an expansion seal is to provide a flexible connection point between two concrete, cement or similar structures. We specifically manufacture our TPE expansion seal profiles to provide excellent abrasion as well as impact resistance. This enables our expansion seals to provide a superior life expectancy compared to similar alternatives.

You can view our standard range of expansion seal profiles on our PDF which is attached to this page. We can also manufacture bespoke profiles to your exact requirements, subject to minimum order quantities and a tooling charge.

Once installed, our TPE expansion seal profiles create a bridge which absorbs the energy created from the two structures moving. This aids structures to efficiently cope with the extreme rates of compression caused by everyday use and adverse weather. Aside from absorbing compression our expansion seal profiles can also create a waterproof seal between two structures. This makes our product ideal for use in bridges and other applications where water and debris can build up.
