Non Fire Resistant Services Penetration Seals


Promat MultiSeal® Cast-in Collars leave a neat appearance after stripping and prevents the exposure of the steel reinforcement caused by coring. Trim off any of the part that extends above the floor slab.

After the installation of the services, backfill the collar with a mortar mix to the full height of the floor slab.

Promat MultiSeal® Cast-in collars are designed to provide openings in cast slabs. The product will not provide a seal in the event of a fire and has no fire resistance level classification.
