  • The control of concrete paving materials (APH). Registration number 04 005 APH 07 B.
  • The control of masonry mortars (AMC). Registration number 04 005 AMC 07 B.
     
Laboratorio de Ensayos Técnicos, S.A. (ENSAYA), has at its disposal material means, facilities and equipment of the most advanced technology.
 
The expertise developed by ENSAYA in this field is divided into:

 

ON SITE TESTING:

     DEEP FOUNDATION

  • Auscultation of piles with the Cross-Hole technique


      STRUCTURES
  • Concrete consistency.
  • Sample drawing of concrete and corrugated steel.
  • Propagation speed of ultrasounds in hardened concrete.
  • Determination of the rebound index with sclerometer.
  • Load tests on structures.
  • Study of the reinforced contingent in hardened concrete with cover meter and by Grooving.
  • Suitability of the soldered joints measured by penetrating liquids, ultrasounds, magnetic particles, visually.
     

      COATING
  • Adhesion test.
  • Pull-off test.
  • Determination of the skidding or gliding index.
  • Thickness of paint and metallic coating.
     

      SEALING:
  • Load testing on sealed surfaces, carpentry or railing.
  • Tests of sealing of roofs, façades and carpentry.
  • Sound insulation tests.
