Introducing the GENFOAM-S

The GENOTEK GENFOAM-S Series is a high-performance, lightweight compression foam system featuring a pre-cured, factory-applied sealant coating designed for traffic-rated horizontal expansion joints. This robust joint sealant is composed of a closed-cell ethylene vinyl acetate (EVA) copolymer foam that establishes a watertight, dust-proof, and UV-stable primary seal without the need for invasive anchoring. Ideal for seismic movement, bridges, and parking structures, the GENFOAM-S system includes a colorized silicone skin for superior chemical and puncture resistance, ensuring long-term durability and a professional architectural finish for large-gap and retrofit applications.

seismic movement accommodation

designed to accommodate dynamic joint movement by compressing and expanding as needed while maintaining its structural integrity.

water protection

creates a robust, watertight primary seal through its pre-cured, factory-applied sealant coating and closed-cell eva copolymer structure. unlike traditional sealants, this system does not rely solely on the silicone coating for its waterproofing capabilities; its monolithic construction ensures an impermeable barrier that remains watertight even under compression, tension, and shear forces. this makes it an ideal solution for horizontal expansion joints and below-grade connections where maintaining a dry environment is critical.

load bearing

specifically engineered for high-traffic environments, featuring a pre-cured, factory-applied sealant coating that meets traffic-rated standards. its robust closed-cell eva copolymer structure exhibits excellent compression and shear capabilities, making it a reliable solution for heavy-load applications such as highway longitudinal joints, bridges, and parking structures. to further protect the system from vehicle impact and prevent edge erosion or spalling, the installation recommends a tooled radiused edge on the adjacent concrete.
