Where structural steelwork is subjected to high humidity, mechanical impact, or extreme industrial conditions, aesthetic thin-film coatings may not provide the rugged resilience required. At FSD Maintenance, we deliver specialist cementitious fireproofing applications across Kent and the South East. Utilizing premium, lightweight gypsum or Portland cement-based formulations, we spray-apply a dense, plaster-like thermal barrier directly onto structural steel beams, columns, and concrete decks. This heavy-duty system insulates the architectural framework against intense heat, preventing critical structural failure in high-risk zones.
Our cementitious spray applications offer a highly efficient and durable solution for hidden or high-exposure building zones:
Provides a highly economical method for fireproofing extensive areas of structural steelwork where exposed aesthetics are not required.
Ideal for areas prone to intense thermal energy, providing up to 4 hours of certified fire resistance.
Beyond fire protection, the dense matrix of cementitious compounds adds valuable sound-dampening and thermal properties to concrete decks.
Perfect for high-traffic, hidden spaces such as commercial basements, multi-storey car parks, and industrial warehouses.
Formulated using eco-friendly, asbestos-free mineral components that emit zero toxic smoke or gases during a fire.
In industrial and commercial fire protection, compliance must be absolute. All cementitious fireproofing materials applied by FSD Maintenance are third-party certified and rigorously tested in accordance with BS 476 Parts 20-21 and BS EN 13381-4 standards. Our technical team carefully assesses your building’s specific architectural layout to match the application thickness with UK Building Regulations Approved Document B. This ensures your project receives an airtight compliance sign-off from local authorities, insurers, and building control officers.
Because it cures to a rough, plaster-like texture, it is primarily used in hidden or utilitarian areas where visual design is not a priority. Common locations across Kent commercial projects include service plant rooms, concealed ceiling voids, multi-storey car parks, and warehouse frameworks.
Unlike intumescent paint which swells chemically, cementitious compounds are passive insulators. They contain bound moisture that absorbs heat energy and slowly evaporates, maintaining a physical thermal barrier that blocks the intense heat from reaching the underlying steelwork.
Yes. We frequently apply cementitious fireproofing to the underside of concrete floor decks and tunnels. This prevents concrete spalling—a dangerous phenomenon where internal moisture boils during a fire, causing the concrete face to explode outward and weaken the structure.
Absolutely. Modern cementitious formulations are entirely free from asbestos and crystalline silica. They are low-dust, non-toxic, and do not emit harmful volatile organic compounds (VOCs) during or after the application process, making them completely safe for commercial environments.
