Introducing UNIQUE Core Bore Seal Firestop System

Core Bore Seal Firestop System by UNIQUE Fire Stop Products

Top side

We are proud to introduce our latest firestop product invention from Unique Fire Stop Products, our UNIQUE Core Bore Seal (CBS) Firestop System. We’ve worked on perfecting this product for several years because, as former firestop installers, we know this solves a major problem that hasn’t had a good solution before now. When you find yourself on the job and needing to cover, seal and firestop empty core holes in concrete slabs or walls during construction and post-construction, you now have the perfect solution. The Core Bore Seal Firestop System is also completely removable if the abandoned core should need to be reclaimed sometime in the future.

UNIQUE Fire Stop Products Core Bore Seal (CBS)

Bottom Side

Note that there are two slightly different versions of the Core Bore Seal Firestop, one for concrete floors and the other for concrete walls. We sell both. The Core Bore Seal Firestop for use in concrete floors is available on the website. If you have the same need in a vertical concrete wall, please call the factory and we will ship what you need within 24 hours.

How to Use  the Core Bore Seal Firestop in Existing Construction

In existing construction, core holes are often abandoned when sleeves or conduits in a concrete floor or fire-rated concrete barrier are removed. Prior to the invention of this innovative UNIQUE product, abandoned core holes were often left unsealed destroying the integrity of the fire-rated barrier. Or they were filled with concrete making the core hole useless in the future. Our Core Bore Firestop System solves both problems, restoring the fire-rated wall to it’s initial rating while still preserving the function of the core hole in the event it will be used again.

How to Use  the Core Bore Seal Firestop in New Construction

In new construction, sometimes extra core holes are drilled, only to find out they won’t be needed for the foreseeable future. Our Core Bore Firestop System effectively seals and firestops empty core holes in both concrete floors and vertical concrete walls, especially those that may be used in the future, but not necessarily immediately. Unlike other methods that seal the core hole permanently, the Core Bore Firestop is completely removable!

IMPORTANT NOTE: All jurisdictions require that any breach in a fire-rated floor or wall be filled, even overnight. When you know the core hole will be used fairly soon, consider installing our UNIQUE Threaded Firestop Sleeve System and our UNIQUE Threaded Endcaps for Empty Sleeves. This combo prepares the core hole with our most robust firestop sleeve along with included Intumescent Putty and ensures that the core hole is ready to go on a moment’s notice when the need arises.

Easy to Install with NO TOOLS!

Our Core Bore Firestop System saves installation time and money while meeting all building codes. It is made of high-grade steel plate (0.60) and an intumescent firestop muffin (plug). It comes with everything needed to install it except the Silicone Firestop Sealant, available on this website.

IMPORTANT NOTE: Our Core Bore Seal Firestop System was UL tested using STI’s Silicone Firestop Sealant and they must be used together for UL compliance and to obtain AHJ acceptance. This brand of sealant is available to purchase on our website.

How to Use  the Core Bore Seal Firestop in Concrete Floors

For concrete floor installation, the Core Bore Seal is inserted into the core hole with a bead of Silicone Firestop Sealant under the top plate. This will smoke seal the Core Bore Seal to the slab or wall. The top plate can be covered by carpet. System may be removed when the core hole is again needed.

Note: If you plan to use the UNIQUE Core Bore Seal for a vertical concrete wall, please call the factory to order a slightly modified product specifically for vertical installations. We want to ensure your success!
