Tunnels and structural elements
La Ventilla Subway station is and old station that has been used from a lot of years ago with out problems. This area of the city 7 years ago started to be changed and a new avenue was going to cross the station. This old station was no calculated to a new cover of 2 metres of soil because was necessary elevate the level of the street. The first possible solution was to reinforce the concrete structure. This solution was too expensive, difficult and very slow. Finally the best solution was a light weight filling with Leca that made possible not to reinforce the station. In 3 days a very important and expensive problem was solved with a filling of 4.000 m3 of Leca®.
