Fire Stopping & Penetration Seals

Certified Fire Stopping & Penetration Seals in Kent

When utilities like cables, plumbing pipes, and HVAC ductwork pass through fire-rated walls and floors, they inevitably leave gaps. Without professional intervention, these openings act as direct pathways for toxic gases, smoke, and flames during a fire. At FSD Maintenance, we provide industry-certified fire stopping and penetration seals across Kent and the South East. Our technical team meticulously reinstates the original fire resistance of breached compartments, using advanced, tested materials that expand or insulate under intense heat to offer life-saving protection.

Engineered Fire Stopping Solutions for Modern Utilities

Our team is equipped to seal even the most complex building service configurations, ensuring complete structural compartmentalisation:

Multi-Service Penetration Sealing

Expert treatment for mixed service bundles including copper pipes, plastic conduits, and heavy-duty electrical cable trays.

High-Performance Intumescent Mastics

Application of premium, flexible acoustic and fire-rated sealants designed to accommodate natural building movement.

Fire Batt & Mortar Systems

Installation of high-density mineral wool batts and load-bearing fire mortars to seal large structural openings and floor voids.

Load-Bearing Floor Seals

Heavy-duty compound solutions that restore the structural load capacity of service-penetrated concrete floors.

Comprehensive Digital Compliance

Every single seal we install is barcoded, photographed, and logged into our digital database, providing clear evidence of compliance.

Tested Solutions in Line with BS EN 1366 and Approved Document B

Passive fire protection leaves no room for guesswork. FSD Maintenance installs fire-stopping systems that have been rigorously tested to BS 476 Part 20 and BS EN 1366-3/4 standards. Our work ensures your property fully complies with Approved Document B of the UK Building Regulations. By ensuring that every seal matches the specific fire rating of the wall or floor it sits within (ranging from 30 minutes to 4 hours), we provide third-party traceable certification that satisfies building control, insurers, and local fire authorities.

FAQs

What is the difference between fire stopping and regular draft proofing sealants?

Regular construction sealants cannot withstand high temperatures and will quickly fail in a fire. Certified fire-stopping sealants and mastics contain intumescent properties that expand rapidly when exposed to heat above $180°C, forming a dense char that blocks fire and lethal gases from passing through.

When a plastic pipe melts during a fire, it leaves a completely open hole in the wall or floor. Fire collars and wraps are packed with intumescent material that expands inward with immense pressure, crushing the softening plastic pipe and completely sealing the opening before fire can cross the boundary.

Yes. We frequently operate in live office spaces, schools, and residential blocks across Kent. The materials we use are low-VOC, non-toxic, and virtually odourless, allowing us to carry out structural sealing safely without disrupting your daily operations.

Absolutely. On completion, you will receive a fully detailed, digitally compiled handover pack. This includes a schematic drawing layout, unique ID tags for every single penetration seal, and side-by-side before/after photographic evidence for your safety records.
