On Demand Leak Detection Testing

Our On Demand Electronic Leak Detection protocols are fast, accurate and affordable. Technical Testing Technologies Inc. uses both LV and HV testing procedures to provide  a much more complete and accurate testing results. It simply cannot be done any other way and achieve the results that responsible membrane integrity testing requires. You can be confident that you're getting the protection and peace of mind that you have paid for.  So how does it work?

 

High Voltage Sweep Detection (HV) 

High Voltage Sweep Detection locates a breach or defect in the waterproof membrane. The testing unit produces a high voltage current, up to 36,500 volts of electricity.  This current is applied through an electrode (or broom) to a membrane or roofing surface. If current can pass through a breach or defect of the membrane and roofing material, the testing unit will then make an audible signal and often create an electrical arc. Our technicians are trained to listen for and interpret these signals, allowing the breach or defect location to be identified and documented.

 

Low Voltage Vector Mapping (LV)

Low Voltage Vector Mapping (LV) pinpoints breaches and defects in a waterproofing membrane by creating a positive and negative electrical plate over and under the non-conductive waterproofing membrane. If there are any breaches or defects in the waterproofing membrane, current will flow through the waterproofing membrane and the exact location detected with our specialized testing equipment. Low Voltage Vector Mapping can be performed with or without overburden in place, but requires water to be in and on the surface of the membrane or roof in order to allow current flow.

Gaussan™ ConDuct mesh is required under the waterproofing when the roofing system is loose laid or fully adhered with a vapor barrier which blocks electrical access to the structure, or with a wooden deck. It can also be installed in a mechanically fastened roof to facilitate testing by minimizing the distance water has to travel signaling a leak. The permanent setup includes Gaussan™ ConDuct mesh, boundary cables and access to cable leads if overburden will be installed.

Gaussan™ Real Time Leak Detection Systems

Automatic Always­-On Electronic Leak Detection for All Types of Roofing and Waterproofing;Single Ply, Hot and Cold Bituminous, Modified Bitumen.

Gaussan™ provides the most comprehensive and accurate leak detection system available for hot or cold bituminous, torch-­applied modified bitumen or single ply roofing and waterproofing. Our sensor cables are robust enough to be used not only in building applications, but also in applications as demanding as landfill liners, chemical waste and containment linings and other civil applications.

 

Gaussan™ sensors can be installed under the roofing or waterproofing membrane or actually mopped or torched into the interply of a hot or cold bituminous multi­ply membrane. The sensors are connected to an on­site JACE communicator that provides 24/7 monitoring while simultaneously pinpointing leak locations and time of leakage event. In Most cases a Gaussan™ Always­-On Electronic Leak Detection systems can be integrated into you existing BAS or other building monitoring systems.

Civil Membrane Inspections and Testing

Civil Membranes and Linings require Technical Testing Technologies to have specialized knowledge, and experience with different products and manufacturers in order to properly test these materials these materials.

 

Tanks, pipes, headworks , flow channels and holding ponds have been lined with various Membranes and liners for decades. As a result, inspection of these linings is occurring more frequently as plants get upgraded due to changing demands in water and wastewater treatment technologies.

 

Fluid constantly pushing on a membrane from the inside of a holding tank at extreme pressure is a critical and complex issue. If problems are not identified you can either loose a valuable commodity or a dangerous by-product may be leaking into the facility itself or worse yet into the environment. Technical Testing Technologies has the experience in using a wide array of testing procedures to protect you and your community from such an occurrence.
