Passive fire protection

Putting right what other trades broke

Compartment lines breached during refurbishment, fire stopping that has failed or was never installed, and doorsets that no longer perform. We reinstate them to the tested detail and evidence the fix.

Where the damage comes from

Nobody sets out to breach a compartment line.

It happens one job at a time. A data cabling contractor cores through a wall and moves on. A plumber drops a new pipe through a floor slab. A ceiling comes down for an air conditioning replacement and goes back up without anyone looking at what is above it. A door gets rehung with whatever hinges were in the van.

None of those trades were asked to reinstate anything, and none of them were checked. Years later the compartment line on the drawing bears very little relation to the one in the building.

Remedial work is the process of finding those breaches and closing them — properly, to the system that was tested, with a record of what was done.

What we put right

The defects we are called out to most.

01Unsealed penetrationsCables, pipes, trays and ducts passing through walls and floors with nothing round them, sealed to the tested detail.

02Failed fire stoppingSeals that have cracked, shrunk, been cut back or were the wrong system for the opening in the first place.

03Fire door defectsGaps, seals, hinges, closers, glazing and signage — most doorsets can be brought back rather than replaced.

04Missing cavity barriersCeiling voids, roof spaces and floor voids where the barrier was removed for access and never put back.

05Damaged compartment wallsOpenings cut for plant or access, and abandoned openings left over from equipment that has since been removed.

06Head-of-wall and jointsThe junction between a partition and the slab above it, sealed so it performs as well as the wall below it.
