Passive Fire Protection Remediation
Expert corrective works and fire-stopping installations to restore your building's compartmentation and ensure compliance with life safety standards.
Service Overview
At Greensurv, we don’t just identify fire safety breaches; we provide the technical solutions to fix them. Passive Fire Protection Remediation is the process of repairing and restoring the fire-resistant barriers within your building. Over time, "compartmentation" is often compromised by new pipework, cabling, or general building wear, leaving gaps that allow smoke and fire to spread uncontrollably. Our remediation team specializes in high-quality fire-stopping—sealing every breach with certified, industry-approved materials. Following the latest Building Safety Act 2022 and BS 476/EN 1366 standards, we restore the integrity of your walls, floors, and ceilings, ensuring that fire is contained at its source and providing vital extra time for evacuation.
Professional Fire-Stopping & Penetration Sealing
When utilities pass through fire-rated walls, they create "penetrations" that must be sealed with specialized materials. We provide bespoke remediation for every type of service breach to maintain a smoke-tight seal.
Fitting high-density mineral fiber batts and intumescent mastic to seal large openings around multiple services.
Installing heat-activated collars that crush plastic pipes as they melt, preventing fire from traveling through the void.
Sealing electrical conduits and data cables using specialized putties and foams that prevent smoke leakage.
Filling the joints between fire walls and floor slabs with flexible, fire-resistant seals to account for structural movement.
Re-establishing fire barriers in vertical shafts to prevent the "chimney effect" during a fire.
Structural Fire Protection & Cavity Barriers
Our remediation work also extends to the "hidden" parts of the building’s skeleton. We ensure that structural elements and concealed voids are protected against heat-induced failure.
Installing barriers within ceiling and floor voids to stop the hidden spread of flame and smoke
Applying fire-retardant paint to structural steel beams to ensure they maintain their load-bearing capacity during a fire.
Encasing structural elements or upgrading existing partitions with fire-rated plasterboard to achieve FD30 or FD60 ratings.
Fixing minor non-compliances such as replacing intumescent strips, adjusting closers, or sealing gaps around the frame.
Repairing or replacing fire dampers in ductwork to ensure they close automatically when heat is detected.

Our Process
STEP 01
Defect Review
We analyze your latest PFP Survey or Fire Risk Assessment to create a comprehensive schedule of works.
STEP 02
Technical Specification
Our Greensurv experts select the correct fire-stopping products (mastic, batts, or collars) based on the material of the wall and the service passing through it.
STEP 03
Precision Installation
Our trained technicians carry out the repairs, ensuring every seal is applied according to the manufacturer’s strict guidelines.
STEP 04
Digital Completion Records
We photograph every repair (before, during, and after) and tag each location with a unique ID, providing you with a complete digital "as-built" record of the works.
Frequently Asked Questions
What is "Fire-Stopping"?
It is the process of sealing any gaps or openings in fire-rated walls and floors to prevent the spread of fire, smoke, and heat.
Can I use standard expanding foam for fire-stopping?
No. Standard "DIY" foam is highly flammable. Only certified intumescent foams or specialized fire-stopping materials should be used.
Do I need to evacuate the building during remediation?
Usually, no. Our work is localized and non-disruptive, allowing your business or tenants to continue as normal while we work in specific areas.
How do I know the work has been done correctly?
At Greensurv, we provide a "Certificate of Conformity" and a digital photo log for every single penetration we seal, giving you total transparency.
How long does fire-stopping material last?
Most modern fire-stopping materials are designed to last the lifetime of the building, provided they are not disturbed by new renovation works.
