InnoTek solutions for undergroundInnoTek Srl was at the recent WTC 2009 conference to present a new series of products and solutions for underground works. Five product families have been developed to increase on-site safety and improve TBM availability. Among these are polymer resins, with superior performance and low fire risk; surfactants and polymers that generate constant pressure against the excavation front, decreasing energy demand and facilitating ground removal; non-toxic gaskets that prevent penetration of water, mud and dirt into the TBM bearing and shield; head tools, with extremely low wear that improve excavation performances; and materials for prefabricated concrete segments, including guide bars and the all-new nylon maxi-screw and plug that feature extremely high pull-out and shear resistances.The company is currently involved in metro construction in Salonicco, Rome, and Tehran; railway tunnels at Brenner, Pajares, and Llobregat; hydro at Beles e Gibe in Ethiopia; and a road tunnel at Los Bronches in Chile.
