Earthquakes can wreak havoc on buildings.Expansion joint system use a closing system that automatically reseals itself after a seismic event or a flexible cover, which can prevent floor and wall finishes from damage. Gravity activated seismic floor covers also return to a normal position after an event. Expansion joint system can minimize facility damage, offer occupants safe egress, and provide structural resilience against seismic activity.
Every building has unique movement criteria, making it important to understand how to integrate movement into expansion joint sizing and coverage. Sizing the building’s expansion joint appropriately to accommodate the joint cover assemblies and any accessories (such as fire barrier, insulation, or vapor barriers) is necessary to ensure top performance during and after an event.
What joint finishes will compliment your space? Working with your manufacturer closely will ensure an effective solution that naturally blends with the existing structure. Consider how daily building movement may displace cover systems. To avoid an undesired finish or hazard, select a qualified installer to ensure a quality installation with the desired finish.
Expansion joint covers that bridge the gaps created by seismic retrofits are critical elements that positively affect structure stability, occupant safety, and building aesthetics. Providing new buildings and existing structures with enhanced measures greatly increases resiliency and long-term property value. Bestowing your property with the capability to withstand a seismic event is a critical step that’s never too late to consider.
