“GLOBALSEAL-TBM/C-1P”
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.
