ELECTRONIC LEAK DETECTION (ELD)
Advanced, Non-Destructive Diagnostics for Total Building Envelope Security
Water intrusion is a leading cause of construction defects, yet traditional leak detection methods often only identify moisture after the damage has already occurred. Terra-Petra’s Forensic Waterproofing Division employs state-of-the-art Electronic Leak Detection (ELD) technology to provide absolute, proactive confirmation that a waterproofing membrane is fully intact and watertight.
In accordance with ASTM Standards (ASTM D7877-14), our non-destructive ELD testing pinpoints membrane breaches down to the millimeter. Whether scanning horizontal plaza decks, vertical walls, pools, or complex roofing systems, ELD is far more accurate, timely, and cost-effective than traditional flood testing. It allows property owners and contractors to identify and repair invisible vulnerabilities before overburden is placed or catastrophic damage occurs.

Unmatched Field Experience & Forensic Precision
While traditional methods like flood testing are expensive, time-consuming, and often inconclusive, Terra-Petra’s ELD services deliver precise, actionable data. Conducted by our in-house certified and accredited inspectors, our third-party ELD verification ensures that the exact location of a leak is identified, repairs are made accurately, and structural warranties remain intact.
Terra-Petra serves as your single point of contact, seamlessly bridging the gap between field investigation, building science analysis, and contractor execution.
-
Pinpoint Accuracy:
Locating the exact site of a membrane breach—even those invisible to the naked eye—rather than just identifying areas of pooled moisture. -
Proactive Quality Assurance:
Identifying trade damage during installation so immediate repairs can be made prior to the placement of overburden. -
Cost & Time Efficiency:
Providing a safe, conclusive substitute for traditional flood testing that requires minimal water and zero structural overload. -
Comprehensive Application:
Validating the watertight integrity of roofs, plaza decks, pools, covered reservoirs, and vertical exterior walls. -
Certified Third-Party Verification:
All testing is conducted strictly in accordance with ASTM standards by accredited industry experts to ensure defensible results.
