Compartmentation divides a building into fire-resisting cells so that fire and smoke are contained long enough for safe evacuation and fire service intervention. We install and remediate compartment walls, floors, risers and ceiling lines — closing service voids, head deflections and abutments with tested systems — so the line of resistance is genuinely continuous rather than only on paper.
Main contractors building to a fire strategy, and building owners or FM teams addressing failed compartmentation surveys, missing cavity barriers or post-Grenfell remediation works.
Required under Approved Document B and the Regulatory Reform (Fire Safety) Order 2005. Higher-risk buildings must evidence intact compartmentation under the Building Safety Act 2022 regime.
- Compartment line survey against fire strategy drawings
- Installation of fire-rated partitions, ceilings and cavity barriers

- Door and glazing interface detailing
- As-built compartmentation drawings with photographic audit trail
Confirm the compartment line, service routes, substrate condition and fire strategy requirement before work starts.
Match each detail to a tested system scope, product data sheet and installation sequence.
Deliver the works with qualified operatives, staged inspection and coordination around other trades.
Issue photographs, locations, product records and certificates in a format the client can retain and audit.
