Ports

Sealing systems engineered for marine exposure and critical operations. Ports operate at the intersection of land and sea, where constant movement, salt erosion, and heavy mechanical loads place exceptional demands on infrastructure. From substations and control rooms to service tunnels, utility buildings and dockside assets, every penetration must withstand moisture, corrosion and operational wear.

“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.”
