Sentinel™ LEJ expansion joint system


Sentinel™ is a longitudinal expansion joint designed to form a flexible watertight seal by spanning the gap between adjacent structures. It consists of a durable, highly flexible elastomeric seal that is clamped to the substrate with aluminium clamp rails, which are then bolted to the structure. The Sentinel™ LEJ system has been developed as a surface mounted joint between adjacent structures, as a soffit mounted flexible watertight gutter detail and as a watertight seal at a deck/wall interface

Benefits: • Accepts a wide range of movements up to 220mm • Maintenance free • Provides flexible waterproofing continuity between structures
