Our expert team can advise on the best transit system for your project, ensuring compliance and long-term reliability in even the most demanding environments.

Multi Cable Transits
Flexible, high-performance sealing for complex cable routes. Modern infrastructure depends on large volumes of power and data cabling, often routed through shared penetrations in walls, floors and bulkheads. Without effective sealing, these openings can compromise fire safety, watertight integrity and overall system reliability.

“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.”
