LABORATORY TESTS
We carry out a full range of tests to characterize the identification and mechanical properties of soils, including granulometry, plasticity, resistance and permeability.
01
Concrete and Aggregate Tests
+
- Inspection of concrete structures
- Formulation studies
- Concrete control to verify mix formulas: compression test
- Sampling and laboratory tests
- Factory monitoring of prefabricated elements
02
Soil Tests
+
- Geotechnical soil identification tests:
- Granulometric analysis by sieving or sedimentometry
- Determination of Atterberg limits (liquid limit and plastic limit)
- Determination of the blue value (stain method)
- Determination of the Sand Equivalent (SE)
- Determination of the content of organic matter, water, etc.
- Determination of density
- Strength and consolidation tests:
- Direct shear
- Triaxial
- Oedometry</li
- Soil compaction tests:
- Proctor tests
- Modified Proctor tests
- Plate tests
- CBR bearing capacity tests
03
Bituminous asphalt
+
- Bituminous asphalt is a coating widely used in road construction. It is essentially made up of a mixture of hydraulic binder and aggregates. The manufacturing and compaction methods require rigorous and quality controls. MAT-SOIL offers:
- Formulation studies
- Mix verification
- Bitumen content tests
- Marshall tests
- Duriez tests
IN SITU BOUNDARIES AND TESTS
MAT-SOIL has boring workshops for different diameters of two hundred and fifty mm
(250mm) and can go to depths greater than one hundred meters (100 m).
01
Equipment and Personnel
+
- Our drilling rigs are equipped with “tracks” and therefore capable of moving on any type of terrain.
- We have high-performance drilling equipment and personnel composed of qualified and experienced drillers and driller assistants.
- Our experienced team carries out in-depth soil condition surveys to inform the planning and design of your projects.
02
Types of Surveys
+
- Core drilling
- Penetrometer surveys
- Pressure meter surveys
- SPT surveys
- Wireline coring
GEOTECHNICAL ENGINEERING
The stability of a structure (buildings, roads, bridges, dams, etc.) depends largely on the integrity of its foundations.
01
Services Offered
+
- MAT-SOIL is able to determine the mechanical, physical and hydraulic characteristics of the different soils or rocks encountered on the site that will house a future project.
- The results of our various studies will allow design offices or other designers to make a correlation between soil constraints and expected loads, and propose the types of foundations adapted to your project.
02
Technical Assistance
+
- MAT-SOIL assists you from the design to the completion of your geotechnical works:
- Preliminary geotechnical studies: Mission G1
- Design geotechnical studies: Mission G2
- Execution geotechnical studies: Mission G3
- Geotechnical supervision studies: Mission G4
- Geotechnical diagnostic studies: Mission G5
TOPOGRAPHICAL STUDIES
Our laboratory offers you solutions in execution and control topography.
MAT-SOIL provides you with suitable answers whatever the scale of your projects.
01
Equipment
+
- Our latest generation digital equipment allows us to carry out all types of topographical studies and extract highly precise data from them. Their processing via this software allows us to anticipate many needs (road layout, buildings, etc.) and to produce scalable models.
GEOPHYSICAL STUDIES
Geophysical surveys can be used at different stages of the geotechnical study. They allow us to assess the heterogeneity
of the study site and to judiciously implement the surveys or to deal with a very specific problem such as the search for cavities.
01
Proposed Methods
+
- Proposed Methods
- Seismic Methods
- Electrical Methods
QUALITY CONTROL (QA/QC) OF GEOTECHNICAL & ROAD WORKS
MAT-SOIL is able to carry out the monitoring, control and surveillance missions of the various geotechnical and/or road works.
01
Team and Expertise
+
- Indeed, MAT-SOIL will provide a team of experts with significant experience in the supervision and compliance control of geotechnical and road works in order to contribute to the prevention of technical hazards likely to be encountered during and after the construction of the works or roads.
