Sealing Crack Injection for Tunnels

Acrylate Gel

  • Adjustable reaction time
  • High mechanical strength
RUBBERTITE®

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
VARIOTITE

Adjustable, rapid-reacting acrylate gel

  • Very good elongation properties
  • For renovation of dilatation joints
ECOCRYL

Adjustable, low viscous, quickly reacting 3 C acrylate gel

  • Quickly reacting

Polyurethane Resin (PUR-I)

  • Flexible hence good movement assimilation
  • Penetrates even into hairline cracks
PUR-O-CRACK

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
PUR-O-RIP

2-component high flexible injection resin based on polyurethane

  • Universal and economical
  • Highly flexible < -50°C

Injection Resin Based on Polyurethane (SPUR)

PUR-O-STOP

1-component injection resin based on polyurethane

  • Stopping of inrushing water

2K injection resin on polyurethane basis

PUR-O-STOP FS

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
HYDROPOX EP1

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
F8000

  • No ettringite formation
F9200

Ready to use dry mixture.

  • Grain size 0-0,125 mm
  • For injection in cracks above 0.375 mm
  • Non-shrinking
  • Swelling
F9300

Ready to use dry mixture, non-shrinking.

  • Grain size 0-0.8 mm
  • Injection an anchor mortar

Curtain Injection

Tunnel: Curtain injection

  • Waterproof up to 12 bar
  • Adjustable to soil conditions
  • High chemical resistance
  • Long-term tested
  • Worldwide references available
RUBBERTITE®

Rubber-elastic, 3 C acrylate gel, multi purpose applicable

  • Very low viscous with high flexibility
  • Very good penetration, even in water filled cracks
