CIVILS watertight integrity for underground substructures
Underground substructures such as basements, tunnels, shafts and service chambers are particularly vulnerable to water ingress. Left unsealed, even minor leaks can compromise structural integrity, damage equipment, and increase safety risks for people working in these environments.
CSD delivers proven sealing solutions to maintain watertight integrity across all types of below-ground infrastructure. Our systems are trusted by utilities, contractors and developers to safeguard critical assets and extend the life of civil engineering structures.
Your Challenges
- Constant hydrostatic pressure from surrounding ground conditions
- Water ingress leading to structural deterioration or flooding
- Complex penetration layouts with multiple ducts and services
- The need for durable, low-maintenance sealing solutions in hard-to-access locations
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.”
