In the field of public works, we carry out quality checks of all types of infrastructures: Urban development projects, main roads, dual carriageways, dams, reservoirs, ponds, canals, supply and plumbing networks, sewage treatment plants, etc.
To carry out this control, we rely on a team of professionals who are specialised in each of these fields, as well as the adequate means of material.
ENSAYA 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:
- Control of mass concrete and reinforced concrete and its constituent materials: cement aggregates, water, steel for rebars, additions, and additives.
- The field of soils, aggregates, bituminous mixtures and its constituent materials in roads.
The performance of the field consists in the quality assurance of the work units that define a public works project.
The most significant tasks are:
EARTHWORKS
- Prior studies on materials on their exploitation for alternative usage.
- Prior studies on recycled materials on their exploitation for alternative usage.
- Characterisation tests of materials for their classification and the determination of their usefulness according to the specifications and the applicable regulations.
- Process control of embankments and backfilling, determining the degree of compaction by means of “in situ” definition of the density and humidity, through nuclear methods.
- Load testing with static and dynamic plate to define the vertical deformation of embankments and backfilling.
- Type testing for CE marking of aggregates.
PAVEMENTS
- Characterisation and suitability tests of natural or artificial materials used in sub-base and base layers, as well as the process control in accordance with the required specifications.
- Analysis of materials used in the fabrication of bituminous products.
- Determination of the characteristics of bituminous mixtures used in pavement layers.
- Process control of layers of asphalt mixtures.
- CE marking of asphalt or bituminous concrete.
PREFABRICATED ELEMENTS OF URBAN DEVELOPMENT:
- Characterisation and suitability tests of pipes of mass concrete and reinforced concrete, PVC, polythene, etc., used in sanitary sewer networks, supply and canalisation.
- Characterisation and suitability tests of road kerbs, paving stones, flagstones, terrazzo and overall materials and elements used in urban pavings.
STRUCTURAL ELEMENTS
- Control of concrete and steel used in the construction of structures.
- Load tests on bridges and other structural elements
