TAIL SEAL COMPOUND FOR TUNNELLING MACHINE TAIL SEALS
“GLOBALSEAL-TBM/C” and “GLOBALSEAL-TBM/C-EC” is a sealant used
in tunnels excavated with full-section mechanical cutters to prevent back-
filling grout, water and mortar penetrating the shild and reaching the
cutting face.
“GLOBALSEAL-TBM/C” and “GLOBALSEAL-TBM/C-EC” has excellent
pumping properties,adheres to all surfaces and offers excellent water
wash-out resistance, even in the presence of salt water. It is formulated to
resist high pressures.

TAIL SEAL COMPOUND FOR TUNNELLING MACHINE TAIL SEALS
“GLOBALSEAL-TBM/C-1P” sealant is formulated as a “First Fill – (TBM/C-1P)” product
to resist water and ground pressures and not break down under high mechanical
pressures.
After the initial “First Fill – (TBMC/-1P)” application, the use of “GLOBALSEAL-TBM/C”
and “GLOBALSEAL-TBM/C-EC” sealant is recommended to ensure effective TBM tail
shield protection.
The average consumption for lling a 3 row brush system is 45 kg per meter shield
circumference.
