Permanently Embedded, Fully Automated Leak Detection and Moisture Monitoring Systems

Continuously Monitor Long After the Initial Membrane Installation

Detec’s PermaScan™ leak detection system is the most advanced electronic leak detection technology for monitoring a roofing or waterproofing assembly.  A PermaScan leak detection system ensures the customer benefits from the longest possible service life for the roof, minimizing risk and reducing maintenance costs over time.

The PermaScan™ isolates leaks remotely to a small, defined area, ensuring the least amount of disruption to the overburden should a repair be necessary. Opening shown here is approximately 12″ x 12″ x 18″ deep exposing our Moisture Detection Tape (MDT)


  • Monitors during construction
  • The PermaScan-C (for Conventional Assemblies) system detects moisture at the vapor barrier
  • The PermaScan-I (for Inverted Assemblies) system detects breaches in the waterproofing
  • Produces timely detection to minimize damage caused by hidden moisture
  • Provides cost-effective sustainability through continuous moisture monitoring
  • Monitor the membrane utilizing sensors embedded below the overburden, for accurate and reliable leak detection
  • Ensures peace of mind and the longest lifespan for the roof, building or structure
  • The best Electronic Leak Detection (ELD) system for a green roof

A PermaScan Leak Detection System may also be referred to as a leak location grid or a leak locate array.  The electronics are the DX250 and RMUIII.
