SELDX Ibérica is a company that specializes in the distribution of conductive sheets manufactured by Controlit Factory, which are used for conducting electronic tightness tests on roofs. These tests are suitable for green roofs and buildings where roof protection is important, such as data centers and electrical substations. The company also performs electronic tests using a high-voltage porosimeter directly on the waterproof membrane, whether synthetic or bituminous, as well as a low-voltage scanner to detect leaks in the waterproofing without removing the roof finish, such as flooring, mineral reactors, or green roofs.
