Emseal DSM - trafficable, water-resistant expansion joint system for floors and decks

Sika Emseal DSM System is a watertight joint system for horizontal-plane applications including Decks, Stadiums & Below-Grade Walls. Traffic durable, joint-face adhered and precompressed, DSM System is a primary seal for deck expansion joints. DSM’s toughness and resilience come 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) 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, ‘caulk-and-backer rod’ and other predecessor technologies, DSM does not suffer from compression-set nor does it rely on adhesion in tension for its performance. Highly configurable, the DSM System uniquely handles changes in plane and direction essential to ensuring continuity of seal.
