This system can be distinguished between wet and dry, depending on the characteristics of the surface to be examined.

<\/p>

Dry<\/strong><\/p>

In the case of a dry and\/or semi-dry waterproofing membrane, testing will be carried out using high-tension technology, better defined as the dry method.<\/p>

This system makes it possible to check and test non-conductive waterproofing membranes using high voltage technology by exploiting the dielectric structure of the coating.<\/p>

The loss of dielectric capacity of the coating, due to its alteration, allows the ELD to detect holes, damage and vulcanisation discontinuities.<\/p>

The dry method involves the use of state-of-the-art, microprocessor-controlled instrumentation designed to provide a stabilised DC output voltage that can be adjusted according to the thickness of the coating.<\/p>

A low-voltage coiled cable connects the detection unit to the test probe.<\/p>

The test voltage will come:<\/p>

  • or automatically calculated by the instrument by setting the thickness of the coating with reference to preset BS EN-50356 criteria (if manufacturer's data sheets are available);<\/li>
  • o calculated with a sample of the roof covering present in the building, according to BS EN 60052:2002 criteria.<\/li><\/ul>

    In fact, the test is based on connecting the structure in negative, by means of a ground cable connected directly to the detector, and traversing the entire surface with a probe, which generates high voltage, in search of discontinuities in the vulcanisations and\/or damage to the waterproof covering.<\/p>

    The detection of an anomaly will be indicated by an audible alarm followed by the illumination of a red LED on the front panel of the detector.<\/p>

    If there are any discontinuities in the vulcanisation, holes or cuts in the mantle, an arc spark will also be generated.<\/p>

    \u00a0<\/i><\/p>

    Wet<\/strong><\/p>

    If the waterproofing membrane is particularly wet, it will be tested using the \u201cwet\u201d method.<\/p>

    This system, based on low-voltage technology, involves the use of a conductive cable that will form a loop within which the test will be carried out. This test involves the use of a pulse generator that produces low-voltage current.<\/p>

    A cable connects the generator to the structure, the current propagates over the test surface through two probes generating a pulse.<\/p>

    If there is an anomaly on the mantle, the detection device directs the operator to exactly where it is located.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"
