ASTEC Soft–Eye facilitates the penetration of Tunnel Boring Machines (TBM) through diaphragm walls and secant piles. This unique technology uses cut-able Glass Fiber Reinforced Polymer (GFRP) reinforcement as an advantageous replacement for conventional steel rebars. Since 1996, SANFIELD has established new standards becoming the worldwide reference.
