Flexible Gutter System (FGS)

FGS is a high-performance, fabric reinforced rubber gutter system designed to provide additional waterproofing for expansion joint openings. Constructed from a continuous EPDM (Ethylene Propylene Diene Monomer) rubber sheet reinforced with fabric, FGS offers a durable and flexible solution for managing water infiltration. The system is secured in place using an aluminum mounting plate and Microwaterseal Tape, which forms a watertight seal against adjacent surfaces.

The FGS system can accommodate multi-directional movement, making it ideal for structures subject to thermal expansion, contraction, or seismic activity. It is also available with an optional flexible drain tube assembly, which allows the water collected to be diverted away from sensitive structural or occupied areas.

BASIC USE

The system is primarily used in applications where managing water ingress is critical, such as parking structures, stadiums, commercial buildings, and bridges. FGS functions as a secondary waterproofing system, providing added protection beneath primary expansion joint systems. This makes it particularly useful in scenarios where joints are exposed to the elements or are located above occupied commercial spaces, where water leaks could cause significant damage.

Additionally, the FGS system can be used to extend the life of aging or leaking expansion joints that remain structurally sound and capable of carrying traffic loads. Rather than requiring full joint replacement, FGS can be installed as a retrofit solution to restore waterproofing performance.

product features

• Collects and moves water away from the expansion joint opening.
• Capable of thermal, seismic, vertical and lateral shear movement.
• +/- 100% movement capability with ability to accommodate complex changes in direction.
• Cost-effective solution for remedial repair of leaking expansion joint systems.
• Exceptional solution for secondary protection over occupied commercial or retail office space.
• Rubber gutter is fabric reinforced to minimize material elongation.
• Resistant to UV, ozone, acid rain, most chemicals and extreme temperatures.
• Service life analysis (Arrhenius methodology) confirms that EPDM fabric reinforced rubber gutter will meet or exceed the life expectancy of the surrounding construction.
