FIRESAFE GPG MARINE MORTAR
What is FIRESAFE GPG MARINE MORTAR?
Passive fire protection for marine offshore GMG Marine Mortar
GPG Marine is a mortar applied to seal cable and pipe penetrations through fire barriers. GPG marine is a low-cost solution compared to traditional systems. The excellent fire-resistant properties combined with extraordinary heat absorbent qualities make the product an attractive choice as a fire sealant. When mixed with water the product becomes light green.
Firesafe marine mortar is specifically formulated for marine applications, particularly for sealing penetrations and gaps on ships to enhance fire safety.
Depending on the water/powder ratio one can easily adjust to desired consistency (i.e. from “liquid to sticky paste”). New penetrations can be made in “old” material and resealed. It takes about 45-60 minutes to harden. The product has been tested for IMO-fire (e.g. A60, A0), HC-fire (e.g. H0, H60, H120), and jet-fire (up to 350kW/m2). GPG Marine is mainly developed for usage in marine, offshore, petroleum or other process industries, which need to withstand high fire loads. GPG Marine has high resistance to water/humid exposure and is therefore well suited in a marine environment.
GPG is a powder consisting of plaster, perlite and glass fibre that when mxed with water forms a mortar. The product is intended for use in internal conditions with humidity lower than 85 % RH excluding temperatures below 0 °C and without exposure to rain or UV (category Z2). The mortar hardens into a strong and fireproof material. GPG is used for fire proofing penetrations of cables, pipes and small holes in walls and floors. The mortar effectively prevents fire, smoke, and poisonous gases from spreading between fire cells.
GPG is also used for insulation against noise, drafts, air pollution as well as for finishing work such as repair of scars in concrete, cotter slots, etc. The mortar has excellent finishing properties and adheres to concrete, plaster and steel.
This is a type of fire-resistant mortar used for sealing openings, gaps, and penetrations in bulkheads, decks, and other structures on ships or marine vessels. It’s typically used to prevent the spread of fire, smoke, and toxic gases between compartments or sections of a vessel. Firesafe marine mortar is applied to seal cable and pipe penetrations, as well as small gaps or holes, providing a barrier against fire and contributing to the overall fire safety of the vessel.

Advantages
- Physical Properties: Firesafe marine mortar typically has a thicker consistency compared to sealants This can make it more suitable for filling larger voids and gaps, providing a more robust barrier against the spread of fire, smoke, and gases.
- Durability: Marine mortar is often more durable and resistant to wear, tear, and environmental factors such as water exposure and vibration. This durability can ensure that the fire protection barrier remains intact over an extended period, even in harsh marine conditions.
- Application Flexibility: Firesafe marine mortar can be applied in a variety of configurations, including trowel application for larger gaps or voids and injection application for smaller penetrations. This versatility allows it to be used in a wide range of sealing scenarios on marine vessels.
- Fire Rating: Firesafe marine mortar may have a higher fire rating compared to certain sealants, providing superior fire resistance and containment properties in the event of a fire onboard a vessel.
- Compatibility with Substrates: Marine mortar is often formulated to adhere well to a variety of substrates commonly found in marine environments, including steel, aluminum, concrete, and various composite materials. This ensures reliable adhesion and sealing performance across different surfaces.
- Certifications and Compliance: Firesafe marine mortar may have specific certifications and approvals for marine applications, ensuring that it meets industry standards and regulations for fire safety in maritime environments.
