Description

Drucseal – TBM – C – 1P is a sealant that can be used in tunnels dug with a full-section mechanical cutter to prevent backfilling grout, water, and mortar from penetrating the shield and reaching the digging face.

It is used, in particular, as a product of “first fill’. It is usually applied around 0.4-1.5 kg/m2 through the tunnel cross-section.

Drucseal – TBM – C – 1P must be stored in original, unopened containers at temperatures not above 40° C and not lower than 5° C. This is a non-hazardous, partially bio-degradable, nontoxic product posing no threat to the worker’s safety.

During the transportation (i.e. in wintertime), the product gets frozen, it must be stored at 15-20° C for 24 hours before using the same for transportation at a temperature higher than 40° C. In wintertime, it must be transported inside the insulated containers.

Advantages of Drucseal – TBM – C – 1P 

  • Exceptional water wash-out resistance (even against saltwater)
  • Formulated to resist high pressure
  • High-temperature resistance that reduces the risk of flames in tunneling machines
  • Adhesion to all surfaces
  • Excellent pumping properties
