Project Description
Sector: Mining
Client: Cerrejón
La Guajira, Colombia
Project details:
The project involved the construction of multiple low-permeability barriers designed to control groundwater flow into the open-pit mining excavations.
The barriers were constructed using specialized soil-bentonite mixtures, significantly reducing groundwater migration into the mining areas.
This solution contributes to the hydrogeological management of one of Latin America’s major mining operations and represents one of CIMAS’s most significant references in the mining sector.
Use of long-reach excavators capable of reaching depths of up to 27 metres.
