Compartmentation Surveys
Surveys of compartment lines and breaches, with photographic evidence and registers, mapped floor by floor.
Every breach on a floor plan.
Compartmentation surveys that remediation teams can actually use.
A compartmentation survey is only useful if the findings can be acted on. DefendX surveys every compartment line floor by floor, photographs every breach, and references it to a floor plan rather than a written description alone.
The output is a prioritised remediation programme, ranked by risk and location, that can support Building Safety Act Accountable Person evidence and feed directly into DefendX's own fire-stopping teams.
DefendX surveys compartment lines floor by floor, identifying breaches at service penetrations, gaps and damaged fire-stopping, and produces a photographic register that feeds directly into a prioritised remediation programme.

What it covers
The work, line by line.
Every line is delivered against written assignment instructions and reported into the AOG weekly review.
Breach identification
Penetrations, risers and linear gaps checked for breaches and inadequate fire-stopping.
Photographic register
Every breach photographed and referenced to a floor plan for remediation teams.
Remediation programme
Findings ranked by risk and location into a prioritised programme of works.
What is included
Inside the service.
- Floor-by-floor compartmentation survey against the building's fire strategy
- Identification of breaches at service penetrations, risers and linear gaps
- Assessment of existing fire-stopping condition and adequacy
- Photographic register of every breach, referenced to a floor plan

- Support evidence for Building Safety Act Accountable Person obligations
Why AOG
What you get that you would not elsewhere.
Surveys are floor-by-floor and photographed, not a sample walk-through
Every breach is referenced to a floor plan, so remediation teams know exactly where to go
Findings feed directly into DefendX passive fire-stopping and remedial works
Output is built to support Building Safety Act Accountable Person evidence requirements
One survey team and one remediation team, so nothing is lost in handover
Available across single buildings or a portfolio of blocks under one instruction
Where it is deployed
Sectors using Compartmentation Surveys.
Proof
Operational, not aspirational.
100%
identified breaches tied to a location before remediation
Every identified breach is tied to a location before a remediation operative is assigned.
Questions
Frequently asked questions
What is fire compartmentation?
Compartmentation is the division of a building into fire-resisting sections designed to contain fire and smoke spread for a defined period, giving occupants time to evacuate and reducing damage.
What does a compartmentation survey inspect?
The survey checks compartment lines floor by floor for breaches at service penetrations, risers and linear gaps, and assesses the condition of any existing fire stopping.
How are breaches recorded?
Every breach is photographed and referenced to a floor plan, so a remediation team knows exactly where to go without needing to re-survey the building.
Can DefendX complete remedials after the survey?
Yes. Findings feed directly into DefendX's own fire-stopping and remedial teams, so the same organisation that identifies a breach can close it out.
What handover information is provided?
A prioritised remediation programme, ranked by risk and location, is provided alongside the photographic breach register.
