Passive Fire Stopping & Compartmentation Surveys
Understanding the Effectiveness of Your Passive Fire Protection
Passive Fire Stopping &
Compartmentation Surveys
Passive fire protection plays a critical role in preventing the spread of fire and smoke throughout a building. However, defects, poor installation or unauthorised alterations can compromise compartmentation and increase risk to occupants.
Isoler’s Passive Fire Stopping and Compartmentation Surveys provide a detailed assessment of fire-resisting walls, floors, service penetrations and compartment lines to identify defects, areas of non-compliance and opportunities for remediation.
Our experienced surveyors undertake thorough on-site inspections, producing clear reports that help building owners, housing providers, contractors and duty holders understand the condition of their passive fire protection systems and prioritise remedial works where required.
Our surveys help clients:
- Assess the integrity of compartmentation systems
- Identify defects and compliance issues
- Reduce fire and smoke spread risks
- Support Building Safety Act compliance
- Inform remediation and maintenance programmes
- Create robust audit trails and compliance records
