TUNNELS

The complicated terrain in Andorra led Grup Heracles to enter the field of tunnel building techniques many years ago.

In recent years, Grup Heracles has built several tunnels and, due to the Group’s specialisation in this field, its companies have also been involved in rehabilitation, repair and maintenance work in existing tunnels.

The Grup Heracles workforce includes technicians specialised in this type of underground infrastructure.
