Water-tight covers for open areas

CS’ open air expansion joint covers are ideal for stadiums and spaces with constant vehicular traffic, like parking garages. Choose from winged seal or compression covers that prevent water entry, or noise-resistant seismic metal covers.

Types of Open Air Covers

Flexible Seal

This cover is designed for parking garages and exterior plaza decks. The seal works by compression to allow for movement and pedestrian traffic while keeping the joint water tight. Joint sizes range from 1" to 4".

Seismic Allway™ Metal

These flush-mounted metal floor covers are designed for pedestrian traffic that requires multi-directional movement. The self-centering aluminum center plate remains flush during thermal movement, but temporarily displaces and slides over the floor surface during allowing for vertical movement. Joint sizes vary by model.
