CAC-EARTHGREASE 110
Tail Sealant for TBM
CAC-Earth Grease 110 is a tail sealant to be used on shielded tunnel boring machines (TBM). Together with the wire brushes, the sealant forms an impermeable barrier between the tail shield of the TBM. It effectively seals the gap between the shield and concrete segments to prevent the ingress of water, grout and soil. It performs best when used in conditions with an ambient temperature above 15°C.
AREA OF APPLICATION:
Tunneling with shielded TBMs equipped with a brush seal system.
Primary uses to obtain-
- Excellent sealing properties and resistance
- Excellent adhesion to any metal or concrete surfaces
- Excellent pumping properties
