Emseal SJS-FP System

A seismic plaza deck expansion joint system the SJS-FP System is designed to provide a watertight, trafficable joint system in wide expansion joints in hardscaped decks of split-slab design. SJS-FP expands the use of the SJS System to waterproofed hardscaped split-slab deck designs through the use of structural-slab mounted retainer legs with integral waterproofing side sheets that integrate with the deck waterproofing membrane.

The retainer legs are available in leg heights that can be matched to the topping slab or wear course thickness. The waterproofing side sheets lock into the top of the retainer legs and are embedded in and encapsulated by the deck waterproofing membrane. The SJS System foam/spline assembly installs between the faces of the retainer legs. The foam/spline assembly is constructed from two precompressed foam sealants pre-assembled in parallel adjacent to a heavy-duty extruded aluminum spline. The spline acts as a receptor for attaching the surface-mounted traffic plates that bear vehicle and other loads.

The result is a system that is watertight and covered with a cover plate that is securely anchored into the wear course.
