Tunneling

Sustainable Solutions with Huge Savings Potential

Many existing tunnels are in need of repair, and there's always demand for the construction of new ones. But they are expensive and can't be built overnight. Time and material consumption are particularly critical in tunneling.
Polymer-modified shotcrete saves you time and materials – thanks to much reduced rebound. Large-scale tests show that polymer-modified shotcrete slashes costs for tunnel-shell construction. Often, all you need is 5% polymer additive.

Polymer modifiers optimize shotcrete adhesion and cohesion: concrete exhibits less rebound and offers excellent adhesion, even on critical substrates. What's more, the concrete will exhibit an impressive blend of good compaction and processing properties, higher compressive strength (even with water seepage) and improved CO2 resistance. The new polymer modifiers are available in liquid and powder form and are suitable for wet and dry spraying. Our experts look forward to collaborating with you on finding new ways to make savings in your projects.
