Terratest starts the construction works on line 16 of the Grand Paris Express. The works will consist of the execution of diaphragm walls executed by means of hydrofraise, in situ piles, ground treatment grouting and Jet Grouting at different locations of the line. Line 16 of the Grand Paris Express is part of the major project to extend the Paris public rail transport network promoted by the public company Societé du Grand Paris. This line, located in the north-east of the city, connects Saint-Denis Pleyel Station with Noisy-Champs Station.
On 13 September 2018, a site visit took place on the occasion of the execution of the first project in Spain using GEOPIER System GEO-CONCRETE COLUMNS, attended by the main Andalusian and Portuguese geotechnical engineering firms. The system consists of the execution by means of displacement of a rigid inclusion of concrete, of very high stiffness modulus, which are rammed and compacted in the tip, creating a bulb of greater diameter, to take advantage of the resistance of the ground improved in the tip, extracting then the tool while the concrete is pumped simultaneously, controlling the pressure to avoid concrete cuttings and to assure the integrity of the column. The execution process is fast and very efficient, allowing loads to be transferred through very soft and compressible layers to the underlying levels of greater resistance for the control and reduction of the settlements.
José Candela, President of the EFFC and Commercial Director of Terratest Group, participated as speaker at the Welcome Session of the Conference.
Gerardo Marote, Director of the Engineering and Resources department, chaired the session on deep foundation technologies and pile construction.
Terratest has been awarded a contract in Paris for more than 5 M€.
The project is part of the modernization plan for the Paris Expo Porte de Versailles Convention Centre, where the French company Leon Grosse is executing the construction of the new pavilion 6, whose foundation lot has awarded to Terratest, which plans to complete piling works next May.
