Downloads

TamSeal TG 11 is a driving grade 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 and the concrete segments to effectively seal off any ingress of water, muck and backfill grout back into the TBM invert.

TamSeal TG 11 performs best when used in conditions with an ambient temperature above 15°C.
