At FRS, our problem solving and design skills are often called upon. We recently used these skills, along with our years of fire protection experience to resolve a challenging issue for our construction client. A fire rated blockwork wall had been compromised to allow for the installation of a staircase.

The thickness of the fire rated blockwork wall had been reduced to accommodate the support structure for the internal steel staircase. A steel PFC (Parallel Flange Channel) beam had been recessed and fixed into one side of the fire rated blockwork wall. This resulted in a reduction of the wall’s fire rating status.

FRS were tasked with bringing this fire rated blockwork wall back up-to-code. Given the stairwell could not be changed or taken apart, the FRS team solved the issue by thickening up the opposite side of the wall with a 52mm thick layer of Promat’s Promatect L500.

This solution reinstated the required 2hr FRL of the wall, meant minimal disruption to our client and provided a neat and professional finish.
