TBM tunnelling without chemicals is unthinkable. Normet provides efficient tunnel boring machine (TBM) additives combined with expert advice to fully support our customers. One of the most important considerations in the use of our TBM materials is the environmental impact. Normet TBM additivies have been carefully developed with regards to their eco-compatibility and we continue to be fully committed in the development and manufacturing of “green” chemicals helping you to operate in an environmentally responsible manner.
Our new range of next generation, high specification plant oil based tail sealants compliments our product portfolio. TamSeal TG91 (Driving Grade Tail Seal Grease) and TamSeal TG92 (First Fill Tail Seal Grease) offer significant improvements compared to our existing grades, including reduced consumption, pumpability, washout, fire resistant and biodegradability. The performance of our soil conditioning foams, anti-clay agents and polymers have also been enhanced through product development to provide maximum operational efficiency in TBM advancement rates in soft ground or hard rock.
Normet provide a full range of materials for EPB Tunnel Boring Machine (TBM), Slurry TBM, Single TBM and Gripper TBM systems.
