About 1,200m (4,000 ft) in length, thetunnel plays a key role inrelieving chronic trafficcongestion in the capitol. Amuch thinner shotcrete layerwas applied immediatelybehind the tunnel boringmachine, creating a natural load-bearing ring and minimizing deformation of the surrounding layers of rock. PEN-ETRON ADMIX ® was used to reduce the permeability of the shotcrete walls. PENEBAR SW-55 was used toseal the concrete construction joints. In total, 45 tons of PENETRON ADMIX ® and 2,300 meters of PENEBARSW-55 were used.7
