Sprayed Concrete
For lower health risks and less environmental impact during production than dry mixtures, our wet mix permanent sprayed concrete tunnel linings provide state-of-the-art single shell structures with time and cost reductions in comparison to conventional tunnel designs.

Waterproofing
Conventional sheet membranes are unsuitable for complex tunnel shapes and susceptible to leakages. BASF’s innovative spray applied waterproofing membrane, applied in a sandwich construction between sprayed/cast concrete shells, provides excellent bonding between membrane and concrete to facilitate single shell linings and eliminate potential water paths.

Fire Protection
In a tunnel fire, a thermal barrier prevents explosive concrete spalling without loss in strength of structural concrete or decreased reinforcement tensile strength. High production rates, an even finish, and controlled minimal thickness make the cementitious sprayed thermal barrier MEYCO Fireshield 1350 ideal for both new build tunnels and existing tunnel linings with limited available space.

TBM Solution
Our innovative total solution approach makes TBM drives more successful, even in highly challenging ground conditions. BASF has the largest range of products and services available for TBM tunnelling, suitable for TBM projects of all sizes, including those with the largest diameters and 4 bar water pressure.

Injection
Pre-injecting the ground with microcement is an economical approach to avoid unexpected water ingress, while post-injection may be required for soil stabilization or even structural repairs. BASF offers a complete range of high performance chemical injection products and technical support.

Service
Our global presence supports seamless technology and service transfer for international contractor and design teams. BASF's professional, technical and site support for products and application are recognized as the best in the tunnel construction and mining industry.
