Introducing the Gen B Series

A robust and versatile membrane sealing expansion joint system designed for high-traffic vehicular areas. This one-piece, extruded EPDM seal excels in driveways and multi-story car parks, accommodating joint widths up to 100mm. The Gen B Series offers superior waterproofing, durability, and ease of installation, making it the ideal choice for parking structures, stadiums, and emergency vehicle areas. With its unique winged design and anchor-free installation, the Gen B Series sets a new standard in expansion joint technology.

movement absorption

the gen b series is engineered to handle up to 33% movement in certain hardness levels, ensuring flexibility and durability in dynamic environments. this capability makes it suitable for a wide range of applications, from standard installations to custom solutions for special cases. (include a video demonstration of movement capability)

waterproof integrity

the continuous membrane nature of the gen b series, combined with its innovative installation method, provides superior waterproofing. by eliminating anchor bolt penetrations, the system prevents water ingress at the finished floor level and protects the reinforcement layer of the slab from potential water damage. (include a graphic illustrating the waterproofing mechanism)

Winged Design

The unique winged profile of the Gen B Series provides superior stability and adaptability compared to compression gaskets, ensuring the seal remains in place even with varying joint widths

Anchor-Free Installation

The Gen B Series is installed using epoxy adhesive instead of anchor bolts, eliminating potential weak points for water leakage and reducing the risk of reinforcement corrosion
