A firestop system that can keep fire, smoke and gases from spreading between floors in your building is required by code. A new device spotted by the BUILDINGS team at AHR 2019 meets the code requirements, but also delivers an extra layer of protection – stopping water from flowing to lower floors.

“If you have a water event – say, a toilet overflows or a fire sprinkler gets knocked off – and you have water on the floor, you don’t want water to be able to get through one floor to another and cause property damage, mold or contamination,” explains Chip O’Neil, vice president of business development for Reliance Worldwide Corporation, which produces the HOLDRITE HydroFlame firestop. “This makes each level of the building watertight no matter what is penetrating the floors.”

Designed for concrete buildings, the UL-listed HydroFlame firestop is added to the floors between stories when concrete is poured just like any other firestop system. It provides a pathway for plumbing pipes, electrical conduits and other utilities.

An expanding material inside closes off the gaps between the piping and the sleeve when fire reaches it, stopping the fire from spreading through for up to three hours. A separate seal in the mid-body of the device does double duty by stopping smoke and preventing water from flowing through.
