Filling a whole in Edge of Slab Firestopping

Filling a whole in Edge of Slab Firestopping

We are working on an interior fitout of a space within a high rise building and have found a hole at the edge of slab through the firestopping and smoke seal. The hole is about 3" long and carries through to the floor below. Can you suggest a product that would easily fill this hole and will meet 2 hour fire and smoke separation required between the edge of slab and the back of the curtain wall?

William,

Thank you for reaching out to the Hilti Fire Protection Design Team to assist you with your firestop engineering needs.

We would need a little more information before we can provide any guidance here. I would recommend sending in either a Question request or Engineering Judgment request. For reference, an Engineering Judgment is a custom detail showing your exact application with the firestop components required to maintain the stated ratings.

We are proud to announce the launch of the HILTI CONSTRUCTION PLATFORM (HCP), our company’s new engineering service website. This platform will be the home for all of your Fire Protection Design needs. Instead of emailing a PDF form for a request, the platform enables you to create new Engineering Judgment (EJ) requests, submit revisions to previously completed EJs or connect with an FPE on a question. HCP also enables you to track the status of your request.

You can find more information on how to access this new platform here: http://www.hilti.com/ej (US) or http://www.hilti.ca/ej (Canada.) If you have any questions or require assistance navigating the platform, please call Customer Service for help at 1-800-879-8000 (US) or 1-800-363-4458 (Canada.)

Along with HCP, Hilti is excited to announce our new mobile app for all your firestop needs: Hilti Firestop Selector. Using the Firestop Selector app gives you easy access to the Hilti Fire Protection Design Team from the jobsite, on the road, or in the office to request a new EJ, an EJ Revision, or a Question anytime, anywhere. You can download the app using the appropriate link below.

Hilti Firestop Selector App – Google Play Store

If you have any questions, please reach out to our customer service team at 1-800-879-8000 (US) or 1-800-363-4458 (Canada) for assistance.

Best regards,

Fire Protection Design Team
