Every fire-rated wall or floor is only as good as its weakest point, and that weak point is almost always a penetration — a cable, a pipe, a joint — that wasn't sealed correctly. Fire sealant is the material that closes that gap, expanding or curing to hold back fire and smoke for the same duration the surrounding wall or floor is rated for.We supply and carry out fire sealant work across Abu Dhabi, Dubai, Sharjah, and Al Ain, using certified products matched to the specific penetration, gap width, and fire rating a project requires, rather than a single sealant used for everything.
CALL NOWFire sealant is a fire rated sealant formulated to expand, char, or cure in a way that blocks fire and smoke from passing through a gap or penetration in a fire-rated wall, floor, or ceiling. Unlike standard construction sealant, it's tested and certified to hold that seal under fire conditions for a specific duration, which is why using the correct fire sealant — not just any sealant that looks similar — is what actually protects the rating of the surrounding structure.The distinction matters more than it might seem from the outside, because a standard sealant and a fire sealant can look nearly identical once applied — same bead, same finish, same color in some cases. The difference only shows up under fire conditions, when a standard sealant softens, melts, or burns away within minutes, leaving the exact gap it was meant to close now wide open to fire and smoke. A certified fire sealant is formulated specifically to resist that failure, either by expanding to fill the growing gap as surrounding materials burn away, or by curing into a form that holds its shape and seal well past the point a standard product would have failed. That's also why fire sealant is tested and rated to a specific duration — 30, 60, 90, or 120 minutes, matching the rating of the wall or floor it's sealing — rather than sold as a generic "fire resistant" product with no defined performance behind the claim.
Fire sealant work starts with identifying the exact penetration type, gap size, and the fire rating the surrounding structure needs to maintain, since the correct sealant and application method depends on all three. A cable bundle penetration, a single pipe, and a construction joint all call for different sealant behavior — expansion capacity, flexibility, gap-filling ability — so this assessment isn't a formality before the "real" work starts, it's what determines which product and technique actually get used.Our technicians apply fire sealant to the manufacturer's certified installation detail — correct depth, correct surface preparation, correct curing time — because a fire sealant applied incorrectly can fail to hold its rating even if the product itself was the right one for the job. Surface preparation matters more than it gets credit for: sealant applied over dust, moisture, or an unprimed surface may look fine on the day of installation but fail to bond properly, and that failure won't show up until the sealant's actually tested under fire conditions, by which point it's too late to matter. Depth and curing time are just as easy to get wrong under time pressure on a busy site, which is exactly why we work to the certified detail rather than judging it by eye.Every installation is documented, so if a compliance audit or civil defence inspection asks which sealant was used and where, that record is already on file rather than something we have to reconstruct after the fact. That documentation covers the specific product, the penetration location, and the installation date, which matters not just for the initial handover but for the life of the building — years later, if a renovation or fit-out disturbs a sealed penetration, having a clear record of what was originally installed makes it far easier to reinstate the seal correctly rather than guessing at what's behind the wall.
Intumescent Sealant
Intumescent sealant expands significantly when exposed to heat, filling the gap around cables, pipes, or joints as it swells, which makes it well suited to penetrations where materials might shrink or burn away during a fire, leaving a larger opening than the original gap.
Fire Rated Silicone
Fire rated silicone stays flexible after curing, making it a common choice for movement joints and penetrations that need to accommodate ongoing building movement without cracking the seal over time.
Fireproof Foam Sealant
Fireproof foam sealant is typically used for larger gaps or bulk penetrations, expanding to fill irregular openings around cable bundles, pipe clusters, or larger structural gaps where a bead of sealant alone wouldn't provide full coverage.
We supply and install fire sealant from recognized manufacturers including Hilti, Sika, Nullifire, and Fischer, specifying the correct product line for each project's penetration type and required fire rating. If your project's fire strategy or specification calls for a specific brand or system, we work to that exact spec rather than substituting an equivalent product.

Fire sealant is used anywhere a penetration or joint passes through a fire-rated element — cable entries and cable tray penetrations, pipe penetrations, movement and construction joints, and gaps around ductwork. Each of these presents a different sealing challenge: a single pipe penetration is fairly straightforward to seal cleanly, while a construction joint has to accommodate ongoing building movement without the seal cracking or separating over time.
Cable entry sealing is one of the most common applications, since cable bundles are rarely a single uniform shape, and the sealant has to conform around irregular bundles while still holding the required fire rating. A cable tray carrying dozens of cables of varying diameters doesn't leave a clean, consistent gap to seal — which is why cable entry work often relies on sealants and pillow systems specifically formulated to mould around irregular shapes, rather than a rigid product suited to a single round pipe penetration.
