Fire rated Transit sealing
Large transits carrying grouped cables and pipes are common in power, industrial and infrastructure projects. These penetrations can be difficult to seal effectively, and if not properly managed, they provide direct pathways for fire and smoke to spread between compartments.
CSD’s transit sealing systems are engineered for these demanding scenarios. Offering certified fire resistance, long-term reliability and re-enterable design, they ensure complex service penetrations are protected without compromising flexibility for future upgrades.
Your Challenges
- Large or irregular openings with mixed cables and pipes
- High fire risk from grouped services
- Requirement for long-term, re-enterable sealing solutions
Our Solutions
“CSD Technical Services delivered the water, and gastight sealing works to a high standard across our control room and DNO substation. Their support contributed effectively to our wider climate action plan, including the installation of a new solar farm and battery storage system. We were very satisfied with the work and will be considering CSD for future projects.”
