Geomembrane Leak Detection

Geomembrane Leak Detection – Geomembrane leak detection is a crucial process in ensuring the integrity of containment systems such as landfills, ponds, and reservoirs. Various methods are used to detect leaks in geomembranes, each with its own advantages and applications. Maxpro are able to undertake a full range of electrical leak detection in accordance with the following ASTM standards:

1. ASTM D6747 – 15- Standard Guide for Selection of Techniques for Electrical Detection of Potential Leak Paths in Geomembranes
2. ASTM D7703-2016 – Standard Practice for Leak Location on Exposed Geomembranes using the Water Lance System
3. ASTM D 7007 -16 Electrical Methods for Locating Leaks in Geomembranes covered with water or earthen material D7953 Electrical Leak Location on Exposed Geomembranes Using ARC testing Method

Methods of Geomembrane Leak Detection

1) Electrical Leak Detection (ELD):

• Techniques: Arc testing, spark testing, dipole testing, and water lance testing.
• Purpose: To detect and locate leaks by applying electrical currents and measuring changes in these currents.
• Benefits: Early detection, precision detection, prevention of environmental damage, and ensuring long-term performance of the geomembrane liners.

2) Drone-Based Leak Detection:

• Technology: eLagoon drone.Purpose: Accurate, fast, and highly-sensitive leak detection.
• Applications: Modern alternative for leak detection in various containment systems.

3.) Sensor-Based Systems:

• Technology: Portable devices for leak location on bare or covered liners.
• Purpose: Non-intrusive testing of geomembrane integrity.
• Applications: Continuous monitoring of geomembrane integrity, suitable for various industries including construction, mining, and waste/water management.
