In recent years we have acquired different spare parts for our Akkerman brand TBMs, which have allowed us to have the equipment ready. We have used our tunnel boring machines in 2 emergency projects recently:
- Completion of the construction of the El Valle Collector, with reinforced concrete pipe of 2.13 meters inside diameter for the municipality of Tlajomullo de Zuniga Jalisco.
- Construction of the Jamapa Collector in the municipality of Ecatepec de Morelos (New construction). With 1.22m RCP pipe.
