Firestopping a plastic pipe through an oversized hole
The process for firestopping a plastic pipe through an oversize hole in a concrete floor:
- Use the Quelfire MW Slab as a Shuttering Slab to the lower side of the concrete floor.
- Install the QWW CE Marked Intuwrap around the plastic pipe. Making sure the right size Intuwrap is used for the right size pipe.
- Mix the QF2 Fire Protection Compound with water and pour around the QWW CE Marked Intuwrap.
- The QF2 Fire Protection Compound expands on curing and therefore locks the QWW Intuwrap in place around the pipe.
