Surface geophysics in geotechnics encompasses a set of non-destructive methods used to explore the subsurface first few tens of meters. It plays a crucial role in site investigation prior to construction works by providing information on the nature, structure, and mechanical state of soils. These techniques complement traditional drilling techniques by offering a comprehensive and […]
WORK METHODOLOGYGeotechnical control is carried out by a specialized team, which will be responsible for checking the materials used in the various phases of road construction and civil engineering structures, as well as monitoring their implementation.GEOTECHNICAL CONTROL AND MONITORINGLTPS will be responsible for the geotechnical control of road and concrete used in the various structures […]

What is it ?Measurement standardIt is a reference, with a value and an uncertainty, to which one compares to establish the accuracy and traceability of its results.The lower the uncertainty of the standard, the better its quality. We go from the working standard (high uncertainty) to the primary standard (very low uncertainty). A CALIBRATIONIt is the […]
Aggregates are used in producing concrete and mortars, roadway layers (subbase, base, and wearing course), and railway bed (ballast). They are also used in rockfill and drainage. Our technicians and engineers assist aggregate producers with all issues related to their operations. Whatever the mission, whether it involves product quality control, deposit reconnaissance, or advising on […]
Geotechnical studies are the art of using soil to create infrastructure and/or to ensure its stability and behavior.The use of a geotechnical map reduces technical, financial, and economic risks at all stages in land-use plannings: natural sites or sites to be developed.Failure to adequately account for the risks associated with the geotechnical aspects of a […]
Our technicians and engineers act upon the request of construction companies, project owners, designers (design offices, project managers) and experts to define the composition of an existing roadway, analyze the pathology of a structure and propose technical solutions.The missions carried out by our teams cover all types of works and all types of structuresInstallationsPlatforms and […]
Our laboratory, through all its units and branches, characterizes concrete and its constituents (aggregates, cement, mineral additions, admixtures, mixing water, …) to determine their properties. Our teams and testing facilities allow us to handle your materials, prepare, and sample the necessary test specimens for conducting tests onsite and in laboratories.The range of tests handled by […]
