- Implementation and maintenance on site.
SCL Tunnel Spray-applied waterproofing system
Fast-curing, seamless and fully bonded liquid, spray-applied system specially designed to provide superior bond to shotcrete and accelerate project schedules by allowing shotcrete to be used as a final lining.
Robust, spray applied system, which forms a seamless, intimate bond with the concrete so water cannot penetrate through the membrane and circulate behind it.
Our solutions:
- Liquid, spray-applied membrane: TYTRO® SL 500
Our services:
- Waterproofing design support
- On-site technical support
- Approved applicator network
- Installation training
Water control and soil consolidation injections
DE NEEF® and TYTRO® injection resins deliver reliable water control solutions for tunnel construction.
Designed for ground stabilization, soil consolidation, and void filling, they support a wide range of grouting applications from pre‑ and post‑grouting to umbrella and combi‑grouting techniques.
By effectively controlling water ingress and supporting rock bolting operations, these solutions help secure excavations and keep tunnelling projects on track.
Our solutions:
- Injection solutions: DE NEEF® 1C PU, TYTRO ® 2C PU
Our services:
- Technical support and Special techniques such as DE NEEF® Combi-Grouting and DE NEEF® Combiblock
Concrete lining
Our concrete lining solutions for NATM tunnelling combine performance, flexibility, and sustainability. They allow full control of workability while delivering excellent pumpability, high‑quality finishes, and high early
strength.
Designed to accommodate complex local aggregates, these solutions also extend formwork service life and significantly reduce the carbon footprint of concrete without compromising on performance.
Our solutions:
- Superplasticizers: Chryso®Optima 1000, EnviroMix®, Quad®
- Release Agents: Chryso®Dem
- Shrinkage Reducer: Chryso®Eclipse
- Fibres: Adfil®Strux, Adfil®Ignis
Our services:
- Mix design and on-site technical support
- Fiber-reinforced concrete structural study
- Challenging aggregates study (Clear Test)
- Concrete CO2 footprint optimization
- Release agent application equip. & training
- Pumpability simulator
- Durability studies
