Tunnels are often built with a service life of over 100 years. To ensure this incredible lifespan is possible, it is important to ensure the structure is fully protected and waterproofed to avoid leakage or water ingress.

A tunnel seal has the task of protecting the tunnel construction against damage from moisture or the unintentional entry of water, soils or chemicals.

Our range of spray-applied tunnel waterproofing systems provide robust, highly resistant protection. On-site testing ensures that a completely effective watertight membrane is achieved.
