Core bore seal

November 2, 2023


The UNIQUE Core Bore Seal Firestop System is a revolutionary way to firestop, water and smoke-seal abandoned (empty) core holes in fire-rated concrete slabs and walls. No need to access the floor below during installation!

Use our UNIQUE Core Bore Seal (CBS) Firestop System to cover, seal and firestop empty core holes in concrete slabs or walls during construction and post-construction. The Core Bore Seal Firestop System is completely removable if the abandoned core should need to be reclaimed sometime in the future. Made with a heavy steel plate (0.60) and an intumescent firestop muffin (plug), in the event of a fire, the plug expands, filling the core hole and protecting the building and its occupants according to the fire rating of the barrier.
