Tunnel Preservation and Restoration
Sealing Crack Injection for Tunnels
Acrylate Gel
- Adjustable reaction time
- High mechanical strength
Rubber-elastic, 3 C acrylate gel, multi purpose applicable
- Very low viscous with high flexibility
- Very good penetration, even in water filled cracks
- Long term stable. Proven stability of at least 16 years
Adjustable, rapid-reacting acrylate gel
- Very good elongation properties
- For renovation of dilatation joints
Polyurethane Resin (PUR-I)
- Flexible hence good movement assimilation
- Penetrates even into hairline cracks
2-component injection resin based on polyurethane
- Officially approved system
- Proven against water pressure of 7 bars
- Approved for use in CHF and LMSS plants
2-component high flexible injection resin based on polyurethane
- Universal and economical
- Highly flexible < -50°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 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 above 0.375 mm
- Non-shrinking
- Swelling
Curtain Injection
