Cable tray and pipe penetration through a wall sealed with fire batt and collar

Service Penetration Fire Stopping Manchester

Every cable, pipe and duct that passes through a fire-rated wall or floor breaks the compartment line unless it is sealed with the correct tested system. We close those penetrations properly — so your building holds its fire compartmentation and your handover or remedial schedule signs off cleanly.

The problem we get called in for

Open or badly-sealed penetrations are one of the most common reasons a building fails a fire compartmentation survey. M&E first-fix leaves holes around cable bundles, pipes and trunking; the wrong filler gets used; or nothing gets installed at all before the ceilings close.

On live projects this usually surfaces at the worst moment — a fire risk assessment, a building control inspection, or a client walk-round before handover. That is exactly the point where we are most useful: we can price from your drawings, a marked-up remedial schedule or photos, and get the penetrations closed to the tested detail.

What we seal

Single and mixed service penetrations through masonry, blockwork and plasterboard walls
Penetrations through concrete and composite floor slabs
Cable bundles, single cables, cable trays and basket
Metallic and plastic pipes, including insulated services

Blank openings and oversized holes formed for future services

How we work

1

Survey or drawings

Send drawings, a remedial schedule or photos, or we attend site to record each penetration and the substrate it passes through.

2

Right system for the detail

We select a tested fire stopping system suited to the substrate, the services and the fire rating required by the building’s fire strategy, and install it to the manufacturer’s specification.

3

Install & make good

We work cleanly around other trades — in new-build, refurbishment and occupied buildings — and make good as we go.

4

Records on completion

Photographic records of completed penetrations are available on request to support your fire safety file and handover.
