Civil Design and Hydraulics

At Anddes, we provide comprehensive civil design and hydraulic solutions for mineral leaching facilities, tailings management systems, surplus material disposal areas, earth dams, and other mining components.

Our services are delivered across all required engineering levels, in compliance with international mining industry standards and under rigorous quality control processes.

Our multidisciplinary team of highly experienced professionals provides technical support and advisory services throughout the design, construction, and operation phases, working closely with clients to ensure optimal results within established schedules.

We also provide hydrology and hydraulics services for the efficient management of water resources and sediment transport, applying internationally recognized methodologies and design criteria.

Our engineers have the technical expertise and resources required to support projects in the mining, agriculture, energy, environmental, transportation, and watershed management sectors.

All services are developed in close coordination with our clients, ensuring optimized technical solutions based on detailed analyses of water conveyance, storage, distribution, and protection systems.
