One of the fundamental tasks of ENSAYA is to conduct geological and geotechnical studies. It is accredited by the “Instituto del Suelo y la Vivienda de la D.G.A.” (Land and Housing Institute of the General Management of Aragon) in the following technical fields:
- The field of laboratory tests on soil mechanics.
- The field of taking undisturbed samples, testing and “ in situ” tests of soils.
We are supported by a technical department made up by civil engineers, geologists and draughtsmen.
At our disposition, there is greatly experienced staff carrying out the test drilling, samples, and “in situ” tests, which are necessary for the geotechnical understanding of the territory, working with the most advanced technology:
- 3 TP50D drills on tracks
- TP70 drill on tracks
- 4 TP50 drills on truck
- TP-40 drill on truck
- 3 automatic penetrometers on tracks
- ROLATEC TL-400 Drill on tracks
ENSAYA possesses a completely equipped laboratory of soil mechanics.
The fields of performance of ENSAYA:
- LINEAR PROJECTS: MOTORWAYS, ROADS, AND RAILWAYS.
- HYDRAULIC PROJECTS: LARGE-SCALE DAMS AND RESERVOIRS. WATERING AND WATER SUPPLY TANKS. CANALS AND PIPES.
- CONSTRUCTION: INDUSTRIAL AREAS. SEWAGE TREATMENT PLANTS. BUILDING AREAS. WIND FARMS. LARGE-SCALE BUILDINGS. SINGLE-FAMILY HOUSES.
- MOUNTAINSIDE INSTABILITIES.
- HYDROGEOLOGY
The expertise developed by ENSAYA in this field is divided into:
STUDIES AND REPORTS:
- Geological studies
- Geotechnical description of materials. Filling and dismantling in linear projects.
- Stability of slopes
- Stability of the mountainside
- Borrow pit study. Localisation, aptitude, and volume measuring.
- Localisation of landfill sites
- Geotechnical studies and materials for dams. Sealing of dam wall.
- Hydrogeological studies
- Studies on land improvement
- Foundation laying of public works and construction
FIELD WORK
- Mechanical test drilling. Undisturbed samples, SPT. Testing and sampling.
- Test pits made by backhoe. Testing and sampling.
- Dynamic penetrations
- Electrical and seismic geophysics
- Tests of permeability
- Geological-geotechnical cartography. Analysis of rock mass
- Capacity control
- Control and supervision on the site: foundation laying, levelling, clearing of slopes, and special tasks (piles, anchoring, etc.)
LABORATORY TESTS
- Identification tests: granulometry, limits, humidity, density, etc.
- Tests of resistance and deformability: triaxial test, oedometer test,direct shear test, collision, simple compression, free swelling, maximum swelling pressure, etc.
- Chemical analysis: sulphates, carbonates, soluble salts, gypsum content, etc.
- Normal and modified proctor, C.B.R.
- Permeability, instability
- Ballast testing
