External Wall Penetrations – watertight & fire rated
External wall penetrations are essential for bringing services into buildings. If left unsealed, they become weak points where water, gas or fire can spread. This not only threatens safety but can also undermine compliance and damage critical assets.
CSD provides sealing solutions specifically designed for external wall service entries. Our systems deliver certified watertight and fire-rated protection, ensuring long-term resilience in challenging above- and below-ground environments.
Your Challenges
- Exposure to rainfall, groundwater and external pressure
- Potential for fire spread through wall penetrations
- Complex service layouts with varying cable and pipe diameters
- Requirement for seals that remain effective over the building’s lifespan
