TruGround™ Conductive Primer by Detec Systems

A patented formulation that enables what was, until now, not possible: A truly reliable membrane integrity test for conventional roof assemblies.

Do not be scammed by inconclusive membrane integrity tests on conventional roof assemblies. Valid ELD testing requires a conductive substrate DIRECTLY below the membrane. TruGround Conductive Primer is the only way to specify a conductive layer DIRECTLY UNDER the membrane that doesn’t compromise adhesion or test reliability, ensuring a quick, thorough, and incredibly accurate membrane integrity test is performed.

TruGround Conductive Primer by Detec Systems is the best way to ensure that the waterproof membrane on your conventional roof assembly is watertight. TruGround provides a simple and cost-effective solution that brings true integrity to your membrane by creating the closest, most thorough coverage of the entire membrane.

We have found that there seems to be confusion and myths regarding testing conventional roof assemblies using Electronic Leak Detection. Detec Systems penned a TECHNICAL NOTE in an attempt to clear up the misunderstanding.

Section 5.5 of ASTM D7877 (Standard Guide for Electronic Methods for Detecting & Locating Leaks in Waterproof Membranes) states, “Electric conductance leak location requires that the deck material directly below the membrane be sufficiently conductive for the test method employed. In most instances, a concrete substrate is sufficiently conductive to allow this method. In certain membrane assemblies, where the substrate is non conductive, it may be possible to install a conductive material directly under the membrane to facilitate testing.”  Other conductive mediums, such as vector mapping mesh, is often placed below the coverboard or insulation. The placement of the vector mapping mesh anywhere other than below the membrane, invalidates the test.  Detec Systems strictly adheres to the ASTM D7877 unlike our competition.

FEATURES

  • Provides the required conductivity per ASTM D7877 for valid ELD testing on conventional roof assemblies, including black EPDM
  • Compatible with high and low voltage ELD methods
  • Chemically and mechanically compatible with fully-adhered, mechanically attached and torch-down membrane systems
  • 30-minute dry time under normal conditions
  • Retesting can be performed for the life of the membrane, should a breach occur at a later date
  • Non-reflective, flat black to ensure complete coverage
  • Water-based (non-flammable & solvent-free)
  • Low VOC, meets Southern California’s strict emissions control requirements for primers
  • Roll, spray, or pre-apply to protection boards
  • Easily applied to transitions and details where other conductive substrates cannot be used
  • Each 5 gallon pail covers approximately 1250 square feet on most common roofing coverboards.  Porous substrates such as OSB can reduce coverage rate

 

HOW IT WORKS

TruGround Conductive Primer creates the closest conductive layer possible: complete coverage, directly under the membrane. Before ELD testing, a light spraying of water is applied to the top of the membrane.  The water will pass through any discontinuity and touch the TruGround. When the IntegriScanner mobile testing platform travels over a breach, an electrical circuit is completed due to the moisture transferring through the membrane, alerting us to the breach with the strongest, most reliable signal possible.  Other conductive mediums such as vector mapping wire mesh is often placed below the coverboard or insulation, making the ELD test completely invalid.  ASTM D7877 requires a conductive medium directly below the membrane for a valid test.

DIRECTLY BELOW THE MEMBRANE
