Geotechnical engineering for buildings.
In urban construction, what happens below ground shapes key decisions above ground. GEO provides geotechnical solutions for special foundations, deep excavations and retaining structures in environments that require technical expertise, coordination and adaptability to local conditions.
As a specialist brand of Soletanche Bachy Colombia, GEO combines its expertise in building projects with the capabilities of the VINCI Group whenever required by the project.

Techniques to address below-ground challenges.

Top Down Construction
A construction method that integrates foundations, retaining structures and the building structure, enabling deep excavations to be carried out safely while optimizing construction schedules.
• Integrated design and construction.
• Simultaneous construction of basement levels and the superstructure.
• Early use of the ground-floor slab as a logistics platform.
• Adapted to complex urban projects.

Anchored Excavation
An excavation system based on retaining structures stabilized by ground anchors, enabling basements and deep excavations to be constructed efficiently and safely.
• Integration of retaining walls and ground anchors.
• Integrated design and construction.
• Excellent deformation control.
• Optimized construction schedules.

Deep Foundations
Geotechnical solutions designed to transfer structural loads to competent ground strata using piles, barrettes, micropiles and grouted piles.
• Kelly-drilled piles.
• CFA piles.
• Barrettes.
• Micropiles.
• Grouted piles.
• Diameters from 0.30 m to 2.50 m.
• Depths of up to 92 m.
• Real-time monitoring of drilling parameters.

Retaining Structures
Systems designed to stabilize the ground and control deformation during deep excavations and complex geotechnical projects.
• Diaphragm walls.
• Secant pile walls.
• Contiguous pile walls.
• Sheet pile walls.
• Ground anchors.
• Cut-off walls.
• Depths of up to 92 m.

Specialized Testing
Tests designed to validate and optimize the performance of deep foundations through direct measurements of bearing capacity and geotechnical behavior.
• O-Cell testing.
• Micropile load testing.
• Measured capacities exceeding 4,000 tonnes.
• Record depths in Latin America.

Foundation Strengthening
Solutions designed to increase the bearing capacity of existing structures using geotechnical strengthening techniques.
• Micropiles installed beneath existing slabs.
• Work in confined spaces.
• Installation under restricted headroom.
• Solutions for structural rehabilitation.
EXEGY® Low-Carbon Concrete
A materials solution developed by Soletanche Bachy to reduce the carbon footprint associated with foundations and ground technologies.
• Use of low-carbon concrete.
• Application to deep foundations.
• Integration with geotechnical solutions.
• Material optimization and reduced carbon emissions.
