best for: exterior parking structures, multi-level car parks, stadiums, emergency and service vehicle areas and pedestrian bridges needing a watertight seal.

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 superseal genb is a single-piece extruded epdm seal that accommodates thermal and settlement movement between the slabs, keeping a flush, flexible joint under traffic in car parks, stadiums and driveways.

waterproof integrity

the one-piece extruded epdm membrane has extended wings bonded to the concrete slab with epoxy, so no anchor bolts penetrate the seal. this keeps water out at the finished floor level and protects the slab reinforcement.

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
Winged Design

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
Anchor-Free Installation

EPDM Construction

Crafted from high-quality EPDM, the Gen B Series offers exceptional durability, wear resistance, and longevity, making it the gold standard for expansion joint materials

Quick Installation

The simple epoxy adhesive application process allows for faster installation compared to anchor-based systems, reducing downtime and labor costs

Seal

Extruded EPDM (Ethylene Propylene Diene Monomer) with a hardness of 60-70 Shore A (ASTM D 2240), providing excellent resilience and weather resistance
