"We have installed hundreds of meters of pipe roofing around the country and this is my favorite method". Borja Del Palacio, Geotunnel

Reinforcing the Torrebaso tunnel: So far, five pipe roofing umbrellas have been installed providing quick and effective support ahead of the excavation. Eight more umbrellas are planned, 9 m in length, to support a further 50 m of the tunnel.
