MEYCO® TSG 7 

MEYCO TSG 7 tail-shield sealant is used for shielded tunnel boring machines (TBMs). MEYCO TSG 7 sealant effectively seals the gap between the shield and concrete segments to prevent the ingress of soil, water or grout.

MEYCO TSG 7 sealant is formulated as a "first fill" product to resist water and ground pressures and not break down under high mechanical pressures. After the initial "first fill" application, the use of MEYCO TSG 6 sealant is recommended to ensure effective TBM tail shield protection. MEYCO TSG 7 sealant has excellent pumping properties and adhesion on all surfaces.
