ASTEC Soft–Eye allow the penetration of Tunnel Boring Machines (TBM) through diaphragm walls and secant piles. This unique technology uses cuttable Glass Fibre Reinforced Polymer (GFRP) reinforcement as an advantageous replacement for conventional steel rebars.
The Soft-Eye technology was developed by Dextra in 1996 and successfully implemented for the first time on Bangkok MRT subway stations. It has since become a standard concept in the design of launching / receiving shafts and subway stations.
Dextra has successfully supplied over 500 soft-eyes on all continents. We offers an integrated turn-key solution which includes design, optimization, manufacturing, logistic, and on-site training.
