A watertight expansion joint, the DSM System is for horizontal-plane deck applications. Traffic durable, joint-face adhered and precompressed, DSM System is a primary seal for deck expansion joints. DSMâ€™s toughness andÂ resilience comeÂ from its microsphere-modified-acrylic impregnation and tensionless highway-grade silicone bellows coating.
The system is comprised of 1) pre-compressed, silicone-and-impregnated-foam hybrid; 2) field-applied epoxy adhesive on the joint faces; 3)Â a silicone sealant band that seals substrate voids and irregularities.
An unmatched performance record has established DSM System as a standard for parking deck and stadium expansion joint sealing. Unlike extruded rubber seals,Â â€˜caulk-and-backer rodâ€™Â and other predecessor technologies, DSM does not suffer fromÂ compression-setÂ nor does it rely onÂ adhesion in tensionÂ for its performance. Highly configurable, the DSM System uniquely handles changes in plane and direction essential to ensuringÂ continuity of seal.
DSM System is available in customized sizes to fit almost any horizontal joint.Â Please contact us for a project-specific quote.
