Senqual

At the leading edge of technology

Laboratory

At Senqual the tests and laboratory works are carried out by graded technicians, being their qualification periodically held and affixed in the laboratories.

The main laboratory of Senqual is located in Valadares, Vila Nova de Gaia – Porto – Portugal.
Senqual has also other laboratories to install in the field according to the needs and dimension of the works.
When needed there is a mobile laboratory available, equipped in accordance with the tests required, that enable to give a versatile and rapid answer to the specific needs of the costumer.

Additionally Senqual has teams available to do in-situ tests and works.

Senqual’s laboratories are fitted with brand new and high quality equipment, modern and reliable that is adequate to do the works and tests required.

All the equipment used to evaluate physical quantities
 

as masses, forces, temperatures, etc., are periodically calibrated in metrological laboratories accredited by IPAC (Portuguese institute of accreditation). Additionally, Senqual performs regular intermediate internal verifications of the equipment using calibrated standards.

In all laboratories of Senqual it is affixed the schedule of the periodic calibrations and maintenance operations of equipment. Moreover there is a quality management system that enables to satisfy legal requirements and standards. This procedure enables to correctly perform laboratorial tests and works.

Tests are carried out in accordance with EN and NP EN standards, LNEC (national laboratory of engineering) specifications, as well as ASTM, BS, DIN, UNE, NF standards as requested by the contract document of the works. In the absence of applicable standards, Senqual uses internal procedures for tests based in scientific papers or recommendations of international organizations.

Pathologies

The current trend for rehabilitation and enhancement of the built heritage as well as the inspection of new constructions requires know-how that enable the characterization of the materials and the maintenance status of the structures: buildings, viaducts, bridges, etc..
The Senqual main laboratory is fitted with adequate equipment and graded technicians that enable a full evaluation of the pathologies of the materials and the pathologies detected in structures.

 

Pathologies of materials

 

  • Hydraulic concrete
  • Bituminous mixtures
  • Ceramics
  • Metallic coatings
  • Wood

Pathologies of structures

Assessment of:

 

  • Corrosion of steel on reinforced and prestressed concrete;
  • Mapping of cracks in structural and non-structural elements;
  • Carbonation in reinforced concrete structures Depth of penetration of chlorides in concrete structural elements;
  • Alkalis content in concrete structural elements;
  • Chlorides content in concrete structural elements;
  • Cover thickness of steel in reinforced concrete elements;
  • Humidity detection in buildings;
  • State of conservation of interior and exterior coatings of buildings;
  • State of conservation of bituminous coatings of roadway pavements;
  • State of conservation of coatings using bituminous screens.
Other works and tests

Additionally, Senqual performs a couple of other services, namely:

 

  • Extraction of concrete and bituminous cores;

 

  • Sampling: soils, aggregates, natural stone, bituminous mixtures, concrete, cement, fly ashes, water, admixtures, etc.;
  • Maturity: instrumentation plan with installation of thermocouples to control the evolution of temperatures, enabling to control the evolution of concrete strength and to obtain the hardening curves;
  • Static and dynamic load tests in structures;
  • Assessment and technical advice;
  • Study of composition of concrete, mortar and bituminous mixtures.
