A fire-rated wall or floor only works if every gap in it is sealed correctly — a single unsealed cable penetration, pipe sleeve, or construction joint can undo the fire rating of an entire compartment. Fire stopping is the practice of sealing those gaps, and it's one of the most overlooked parts of passive fire protection precisely because most of the work happens behind walls and above ceilings, out of sight once a building's finished. We provide fire stopping services across Abu Dhabi, Dubai, Sharjah, and Al Ain, covering every penetration type in a building — cables, pipes, ducts, and structural joints — documented and traceable for civil defence inspection and handover.

Complete Fire Stopping & Passive Fire Protection Solutions

Head of Wall Joint Systems

The gap between the top of a partition wall and the floor or ceiling above is a critical area in passive fire protection. We install fire and smoke rated head of wall joint systems that seal these gaps while accommodating the natural movement and deflection of the building structure. Our solutions are suitable for drywall, masonry, concrete, and steel frame partitions in high-rise, commercial, and institutional building

Engineering Judgement (EJ)

When standard fire stopping solutions cannot be applied to complex or unique construction situations, our qualified engineers provide formal Engineering Judgement reports. These site-specific solutions are prepared by certified fire stopping professionals and are accepted by UAE Civil Defense authorities for project approvals and building handovers. We ensure every unique penetration scenario is resolved safely, correctly, and in full compliance with regulations.

Fire Sealant Integrity Testing

Fire sealant integrity testing verifies that all installed fire stopping materials and systems perform to their rated specifications under simulated fire conditions. Our certified inspectors conduct thorough assessments of sealant adhesion, penetration coverage, and joint integrity across all sealed openings. We provide detailed inspection reports accepted by UAE Civil Defence authorities for building compliance sign-off and handover documentation.

Fire Stopping Services

Our fire stopping services cover the complete sealing of all wall, floor, and ceiling penetrations to prevent the spread of fire, smoke, and toxic gases between building compartments. We work across all penetration types including pipe sleeves, cable trays, ductwork, and structural joints — using certified intumescent products, fire collars, and pillows rated to international standards. Every installation is documented and traceable for Civil Defence inspection and building handover.For fire sealant products and specifications specifically, see our Fire Sealant page.

Cable Penetration Sealing

Cable penetrations through fire-rated walls and floors create critical vulnerabilities in a building's passive fire protection system. We seal all cable bundle penetrations using intumescent putty, fire-rated pillows, and mineral wool systems that expand under heat to maintain the fire rating of the surrounding structure. Our solutions accommodate single cables, bundled runs, and mixed cable/pipe penetrations in commercial, industrial, and high-rise applications.

MEP Penetration Sealing

Mechanical, electrical, and plumbing penetrations are among the most common sources of fire compartmentation failure in UAE buildings. Firestone's MEP penetration sealing service covers all pipe, duct, conduit, and cable tray openings through fire-rated elements — using the correct certified system for each penetration type, diameter, and wall construction. Our team works directly with MEP contractors and main contractors to ensure all penetrations are sealed, documented, and compliant before handover.

Civil Defence Compliance & Building Handover

Fire stopping is a mandatory requirement for civil defence approval on any UAE building project — it's checked specifically during inspection because unsealed penetrations are one of the most common reasons a compartmentation strategy fails on paper even when every wall and door was correctly rated. We manage fire stopping as part of the overall compliance process, coordinating with civil defence authorities and main contractors so penetration sealing isn't the item holding up a project's final handover.Every fire stopping installation we carry out is documented against the specific product, penetration type, and location, giving you a compliance record that's ready the moment an inspector or auditor asks for it. For projects with unique or complex penetration details that fall outside standard tested systems, our Engineering Judgement reports provide the additional documentation civil defence authorities need to sign off on a non-standard solution, so those details don't become the reason a handover gets delayed.
