Activities and Services

C.S.I specializes in direct geognostic investigations, essential for understanding the subsurface and fundamental in the design of engineering, road, and hydraulic works. Understanding the characteristics of the soil is crucial for evaluating its properties, its suitability for construction, and compliance with specific regulations governing public and private works.

These investigations are crucial to ensuring construction safety and predicting the long-term impact of structures on the ground.

Geognostic Investigations

Geognostics uses a series of specific procedures, such as drilling, to determine the physical and mechanical characteristics of the soil. These investigations involve extracting cylindrical soil samples, called "cores," which are subjected to analysis and testing.

Continuous core drilling stratigraphic investigations are carried out using special sampling tools that, through a rotation system, extract the samples, allowing an in-depth analysis of soil and rock characteristics.

This process is essential before designing any public or private project.

Environmental Monitoring

Hydrogeology

Piezometric surveys allow, through test drilling, to measure the hydraulic load of an aquifer at a certain depth. The use of piezometers helps reconstruct the surface where the water pressure equals atmospheric pressure. The information obtained from piezometers, such as slope (hydraulic gradient) and groundwater flow direction, enables direct aquifer measurements and, if needed, water sampling at different depths.

Soil Deformation and Displacement

Extensometers are instruments used in geotechnical monitoring to measure the deformation or displacement of soil, rocks, or other materials under various conditions and specific loads. These instruments provide essential data for evaluating the behavior and stability of structures such as tunnels, buildings, bridges, slopes, and retaining walls. A crucial application of extensometers is in dam rehabilitation, where they quantify length variations in a material along a specific direction.

Horizontal Soil Displacement

The inclinometer is an instrument designed to measure horizontal soil displacements at different depths using an inclinometer tube anchored into the ground. This monitoring system is particularly useful for studying landslides and applications such as excavations, dams, embankments, and unstable slopes.

Soil Consolidation

Soil consolidation and waterproofing are two fundamental processes in civil, geotechnical, and construction engineering, used to improve the stability and strength of soil under various environmental conditions and to protect it from water infiltration.
