A geotechnical study makes it possible to identify the type or foundation system needed for a structure (building, road, bridge, etc.). This phase depends on the nature of the soil on which you plan to build, and the geotechnical data of the terrain. Construction soil analysis and laboratory tests make it possible to calculate the bearing capacity of the soil. And therefore, determines the type of foundations and the planning of construction works in terms of:

• backfill
• clearing
• improvement of the mechanical characteristics of the soil

In a geotech study, the lift is defined as the capacity of a soil to withstand the pressure exerted by the weight of the structure to be built. In order to know the bearing capacity, laboratory tests must be carried out. This construction soil analysis makes it possible to determine the geotechnical characteristics of a land. Which includes its nature and its resistance before the foundations are installed.

For this, it is important to know data such as:

• the land area
• the number of floors the structure will include
• whether a basement will be built or not in the case of a building

There is two types of foundations:

• superficial or conventional
•  deep

Some professionals sometimes use the expression semi-deep to speak of an in-between. The surface foundations are generally composed of a concrete foundation wall, the base of which is provided with a footing. The purpose of this sole is to reduce the pressure on the ground. Semi-deep foundations are more suitable for buildings that require more excavation. Deep foundations work with piles of different types sunk into the ground to reach the bedrock or the densest layers of substrates.

The geological study is an essential component of a construction project. Whether as part of projects to do construction work, or repair (basement included).

Indeed, the nature of the soil plays a determining role in the choice:

• foundation systems
• support structures
• materials used on site

The cost of construction soil testing and the schedule of a project depends on the soil characteristics on site and must be taken into account when planning your project.
