Fondasol Senegal

Specialising in sampling, studies, engineering and consulting, the Fondasol Senegal teams analyse all the geotechnical issues affecting your site to recommend solutions to ensure the long-term security of your project while optimising the costs of implementing it.

They also provide monitoring and control during the study and work phases.

Our geotechnical engineering missions cover type G1 ES to G5 missions as defined in French standard NF P 94-500.

Furthermore, our approach based on multiple areas of expertise enables us to mobilise all the experts necessary to the study and modelling of the overall environment of your projects, in Senegal and elsewhere in West Africa.

Sampling & analysis

Acquisition of field data

Mechanical drilling and core drilling: all types of drilling to depths of up to 200 m and diameters of up to 250 mm
Pressuremeter tests: standard, high pressure, cyclic tests
Soil tests: static cone penetrometer (CPT), dynamic cone penetrometer or SPT, phicometer, scissometer
Sampling: intact, remoulded (auger), core drilling
Karst search: borehole logging, photo and video reporting
Geophysics: rapid, global and non-destructive reconnaissance surveys by microgravimetry, ground penetrating radar or seismic, electrical and electromagnetic methods; detection, reconnaissance, search and classification; 2 and 3D modelling and formatting

Geotechnical laboratory

Identification of soils, rocks and aggregate
Mechanical tests and tests on concrete (shear, swelling, compression, triaxial testing)
Concrete formulation (hydraulic, bituminous (hydraulique, bitumineux)

Construction

Geotechnical engineering and design

Dimensioning of foundations: shallow, semi-deep, mixed foundations, rafts, deep foundations
Ground-related structural stability studies: embankments and reinforced embankments; retaining walls; subsurface earthworks
Sub-base studies and ground reinforcement: studies of aggregate or treated sub-bases; soil reinforcement studies
Geotechnical diagnosis of existing structures: landslides, damage to buildings, dimensioning of reworking of classic underpinning, using micropiles, jet grouting, etc.

Geotechnical construction supervision and monitoring

> Internal and external control for contractors,
> External control and technical assistance for project owners and prime contractors,

Earthworks
Special foundations
Retaining works
Backfilling, capping layers, pavements, etc.

Roads & earthworks

Road studies

Outline preliminary design (APS) or final design (APD)
Construction studies

External control/geotechnical construction monitoring

We can monitor the construction and acceptance of foundations and subgrades, as well as dealing with arrest points on construction sites, as part of a quality assurance plan (QAP).

Earthworks: plate bearing tests, compaction testing with a nuclear density gauge; constant and variable energy penetrometer tests; construction monitoring and taking of samples for laboratory analysis; trial areas (establishment and monitoring); installation and monitoring of instrumentation; test geotechnical investigations
Pavement and roadways: auscultation (deflection, pavement borehole investigations, macrotexture, microtexture, etc.); installation of automated instrumentation; monitoring and control of the laying of asphalt; surveys of damage to existing roads

Mining sites

We can mobilise our experts and equipment to carry out mineral exploration campaigns to locate and quantify potential deposits.

Geotechnical engineering
Geology
Geophysics
Topography

A comprehensive approach to engineering consultancy

We can call upon many areas of expertise to accompany your construction and development projects, to bring you comprehensive, pragmatic, sustainable solutions adapted to the specific issues of your projects.
