Jointech® Composite Technology

Jointech® Composite is a patented bridge expansion joint system engineered to accommodate structural movements while providing long-term durability, high corrosion resistance and reliable waterproofing.

The system is built around high-strength Glass Fiber Reinforced Polymer (GFRP) angle profiles combined with an advanced elastomeric expansion element designed to absorb and accommodate movement caused by temperature variations, traffic loading and structural deflections.

At the core of the technology is a unique patented guidance system consisting of solid GFRP support rods housed within specially designed composite sleeves featuring an internally tapered bore. The tapered geometry increases in diameter from the joint profile towards the outer ends of the sleeves, allowing the support rods to move freely while remaining precisely guided.

This patented arrangement enables:

• Controlled longitudinal expansion and contraction

• Vertical movement accommodation

• Shear and transverse displacement

• Angular movement between adjoining structures

The movement envelope is accurately defined by the conical geometry of the sleeves, ensuring predictable performance while minimizing stress concentrations within the system.

To provide complete protection of the supporting structure, Jointech Composite™ incorporates an integrated waterproofing membrane system installed beneath the expansion joint. This creates an effective barrier against water ingress, de-icing salts and other aggressive environmental contaminants, significantly extending the service life of the bridge or structure.

The result is a lightweight, highly corrosion-resistant and low-maintenance expansion joint system designed for modern bridge decks, parking structures and concrete infrastructure applications worldwide.
