Fire Stopping Services
Fire stopping is a critical element of passive fireproofing for any building type. It is also known as compartmentation, and it refers to the process of filling openings and joints with fire resistant material with its sole purpose being to prevent or slow down the spread of fire and smoke by keeping it within the fire stopped zones, savings lives and assets.
When installed correctly, fire stopping measures can contain a fire for up to four hours, giving plenty of time to ensure that everyone on the premises is safe and that the building has been fully evacuated.
Contact BritCut for expert fire stopping measures across London, Kent and Essex.

What Is Fire Stopping?
Fire stopping is the process of sealing openings and gaps in fire-resistant walls and floors to prevent the spread of flames, smoke, and toxic gases.
These systems are a key part of passive fire protection, helping buildings meet legal fire-safety requirements such as Approved Document B and BS 476 / EN 1366.
Properly installed fire stopping can mean the difference between containing a fire and catastrophic loss.
Where Fire Stopping Is Needed
Fire stopping is essential wherever services or structural elements penetrate fire-rated walls, floors, or ceilings — such as:
-
New-build and refurbishment projects
-
M&E installations and riser shafts
-
Service penetrations for pipes and cables
-
Curtain walling and façade interfaces
-
Plant rooms and service corridors
-
Structural steel protection in car parks and warehouses
Our Fire Stopping Services
We provide a complete range of fire-stopping solutions, including:
-
Intumescent coatings – expanding materials that protect structural steelwork and load-bearing elements.
-
Cavity barriers & fire batts – stopping smoke and flames spreading through concealed voids.
-
Pipe and cable penetration seals – maintaining compartmentation where M&E services pass through walls or floors.
-
Fire-rated sealants & collars – flexible solutions for irregular gaps and building movement.
-

All work is installed by trained operatives and completed to third-party certification standards.
