Buildings

Protecting building infrastructure with long-life, multi-hazard performance. Across building developments, service penetrations are often the weakest link in building resilience. Water ingress, fire spread, smoke leakage and poor airtightness can lead to costly failures, safety risks and non-compliance. As buildings become more complex and more technology-driven, the need for dependable, future-proof sealing has never been greater.

“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.”
