2-component high flexible injection resin based on polyurethane
- Universal and economical
- highly flexible < -35°C
Injection resin based on polyurethane (SPUR)
2K injection resin on polyurethane basis
Quickly reacting, rigid, 2 C Polyurethane resin
- Stopping of inrushing water
- For filling and solidification of gravities and ground structures
Solid crack injection for a tunnel
Epoxy resin
- Where pulling and pressing force is expected
Low-viscous 2 C injection resin based on epoxy
- for friction-fit filling of cracks in tunnels
- use also possible on moist substrates
Injection cement
- All cements just needs to be mixed with water and do not need to be mixed up during injection
- Cements are ideal for filling of hollows and for structure solidification with compressive load
- Also available in big-bags
Single-component injection material based on extra-fine cement
- Very high compressive-strength
- For injection in cracks above ab 0,2 mm
Minerally, single component injection glue based on trass chalk according to DIN 1060
- No ettringite formation
Ready to use dry mixture.
Grain size 0-0,125 mm
- For injection in cracks > 0.375 mm
- Non shrinking
- Swelling
Curtain injection
Tunnel: Curtain injection
