Detec New Zealand specialise in testing Waterproof Membrane systems integrity through Electronic Leak Detection (ELD).Too often Waterproof Membranes leak due to either incorrect installation, damage during / shortly after installation by other contractors or simply old age; most too small or concealed to see.Flood testing is not a sustainable practice &amp; adds excessive weight to the building (50mm water x 20m2 = 1,000kg) typically overloading the structure and finding the breach location is extremely difficult and time consuming.Detec New Zealand tests membrane systems using our ELD IntegriScan Low Voltage Scanning Platform with associated Roller Scanning Unit to accurately test most applications in one mobilisation - up to 3700m2 on horizontal surfaces or up to 930m2 to vertical surfaces a day.The IntegriScan System is the only method available in New Zealand that complies to both testing standards ASTM D7877-24 and ASTM D8231-19.Call us to see how we can help you.
