Abstract

LAGUELA-LOPEZ, Susana; SOLLA-CARRACELAS, Mercedes; DIAZ-VILARINO, Lucía  and  ARMESTO-GONZALEZ, Julia. Inspection of radiant heating floor applying non-destructive testing techniques: GPR AND IRT. Dyna rev.fac.nac.minas [online]. 2015, vol.82, n.190, pp.221-226. ISSN 0012-7353.  http://dx.doi.org/10.15446/dyna.v82n190.43913.

The inspection of radiant heating floors requires the use of non-destructive techniques, trying to minimize inspection impact, time and cost, and maximize the information acquired so that the best possible diagnosis is given. With this goal, we propose the application of infrared thermography (IRT) and ground penetrating radar (GPR) for the inspection of radiant heating floors with different floor coatings, in order to evaluate the capabilities and information acquirable with each technique. Specifically, two common floor coatings have been inspected: ceramic tiles and parquet flooring. Results show that each technique provides different information: condition of the pipelines (IRT), geometry and configuration (GPR), concluding that the optimal inspection is constituted by the combination of the two techniques.

Keywords : NDT; infrared thermography; ground penetrating radar; radiant heating floor.
