The DIH Series is a high-performance seismic expansion joint designed for extreme-duty service conditions. It provides a smooth and virtually impact-free transition between adjacent floor surfaces, making it ideal for high-traffic, climate-controlled environments. The system features dual interlocking hinged slide plates that remain flush with the finished floor, ensuring a level surface even during thermal or multi-directional seismic movement. The hinged design allows for seamless expansion and contraction, while maintaining structural integrity.
Equipped with six rubber anti-vibration dampers, the DIH system eliminates metal-to-metal contact, reducing noise and vibration. These dampers also help prevent the infiltration of liquids, supporting cleaner and more hygienic spaces.
Basic Use
The DIH Series is ideal for use in airports, hospitals, casinos, convention centers, and stadiums—anywhere that must accommodate heavy rolling loads such as gurneys, carts, pallet jacks, or forklifts while allowing for seismic movement.
With its robust construction, integrated damping system, and optional waterproofing enhancements, the DIH Series offers a durable, quiet, and low-maintenance solution for demanding expansion joint applications.
Optional Components
Optional components include the TriBlok™ Moisture Barrier, a flexible waterproof membrane, and LokCrete® elastomeric concrete infill, which enhances durability and watertight performance.
