Bridge Expansion Joints – Flexi-Joint

Expansion Joints for bridges and other structure from HMS Decorative Surfacing Ltd.

Our Flexi-Joint system is a Highway Agency approved Bridge Expansion Joint Certificate Number 026.

“Asphaltic Plug Joints” were developed in the 1970’s from a need to replace failed expansion joints and in many cases the adjacent road surface was breaking up when the traditional buried or rigid joint systems began to fail. Many thousands of metres of this joint system have been installed on all major roads throughout the UK.

The key benefits of the “Asphaltic Plug Joint” system is the ingenious use of what is easily described as a ‘super-flexible’ surfacing material. Polymer modified bitumen is carefully combined with selected road aggregates and the resulting ‘asphaltic plug’ design provides:-

• A superior flexible replacement road surfacing material
• A compound which bonds to the bridge deck
• A waterproof expansion joint design

HMS Decorative Surfacing Ltd compliments its extensive range of surfacing solutions with its expertise in polymer modified bridge expansion joints. HMS Decorative Surfacing Ltd is approved to install ‘Asphaltic Plug Joints’ on all classes of highway in the UK.

• ‘Flexi-Joint’ is an Asphaltic Plug Joint and is designed to cater for small to medium expansion gap movement on bridges and other structures. Although simple in concept, ‘Flexi-Joint’ can incorporate sub-surface drainage and is an ideal replacement system.
• ‘Flexi-Joint’ is quickly and easily installed lane by lane if required, thus minimising site possession time and the costly problem of repetitive daily lane closures.
• ‘Flexi-Joint’ is an ideal solution for low range movement joints where noise containment is of prime importance. Some rigid joint systems with metal runners or bolted units can be a headache to residents in urban areas adjacent to high speed flyovers. ‘Flexi-Joint’ has the added benefit of being virtually silent when trafficked at high speed.
