SeisMaxPlus blends its seismic functional features into an aesthetically pleasing “No-Bump” system that has no exposed metal. The system stays flush during thermal movement and operational during seismic movement. But unlike other joints that deform when seismic motion exceeds their capabilities, SeisMaxPlus will rotationally displace the slide plate assemblage during severe seismic movement. This provides the best possible protection for the surrounding structural surfaces. The slide plate assemblage will typically re-seat itself and the elastomeric seal can be easily re-installed.
