Lorena Hospital: our patented Springsol® technique

In October 2022, the SRT consortium, made up of the companies Stiler, Ripconciv and Tecnoedil, won a major contract in Peru to complete the construction of the Antonio Lorena hospital in the city of Cuzco, a project that had been paralysed for several years due to corruption problems.

Part of the project involves improving the existing structures, which were suffering from differential settlement causing cracks in the walls, slabs and beams, apparently as a result of a poor soil survey.

The consortium contacted Soletanche Bachy Peru in early 2023 and, after fierce competition with ground improvement companies, our Peruvian subsidiary won the project in April 2023.

The $1.7 million contract involves improving the foundations in 7 different areas of the hospital. The surface to be treated will be 4,400 m² and 800 Springsol® columns 40 cm in diameter and up to 8 metres deep will be used.

First use of the Springsol® process in Peru and Latin America

Juan Carlos Rivera Baca, Managing Director of Soletanche Bachy Peru, points out that this construction technique is being used on a large scale in Peru for the first time, and that it is a happy coincidence that it is being used in Cuzco, in the “navel of the world”. At the beginning of 2022, he had set up a multidisciplinary working group to develop the soil mixing technique and thus gain market share in soil improvement in the land of the Incas; in December of the same year, they secured an initial USD 140,000 project in Lima.

“Our team received a great deal of support from the group, in particular from Fabrice Mathieu of Soletanche Bachy International and Juan Manuel Dimas of Rodio Kronsa, without whom it would have taken us a long time to implement this technique in Peru,” explains Juan Carlos Rivera Baca.

It should be noted that Soletanche Bachy has made 50% progress on the work entrusted to it and expects to complete it by the second half of October this year.  

The Antonio Lorena Hospital represents an investment of more than 900 million soles (around 235M USD
