Ground improvement for the new international airport in Mexico
Following the award of a contract in late 2016, teams from Menard Mexico are currently working on the project to build Mexico City’s new international airport.
This will be located to the north of the city, on the site of a former lake (4,430 hectares), on a clay soil with a water content of more than 250%. Menard Mexico had participated in 2014 in the creation of a number of trial sites aimed at identifying the soil improvement method best suited to the project and the type of soil. The precharge technique was selected, associated with the installation of prefabricated vertical drains for the runways and taxiways.
This new contract therefore covers supplying and installing the prefabricated vertical drains of the airport’s future Runway 2. In order to install the planned 33 million metres of drains, Menard Mexico has deployed a dozen items of specialised equipment for the drilling of the vertical drains, some of them as much as 27 m in depth.
The works must be handed over in summer 2017, to allow the installation of the precharge and the consolidation of the clay soils.et la consolidation des sols argileux.
