Wet Electronic Leak Detection
Wet Electronic Leak Detection or ‘Vector mapping’ is a method of electronic leak detection applied to identify breaches in waterproofing membrane in new construction and existing structures.
Accurate Leak Location – Even Under Tiles or Soil Layers
Vector mapping is a low voltage method that requires water to be applied in order to complete an electrical circuit as water passes through the breach. This is contrary to holiday testing, our other most commonly used approach to Electronic Leak Detection (ELD), which is a dry, high voltage test
This method can be applied in new construction but will require water being applied and then potentially dewatered depending on the area.
In existing buildings, this method can be used on exposed waterproofing membranes such as roofs and can also be used over tiles on balconies, podiums or rooftops. As such, in some diagnostic applications in existing commercial buildings and strata complexes, this method is the more appropriate approach.
Waterproofing Integrity support a number of commercial and multi-residential assets with regular inspections to avoid large repair costs. These inspections can be visual only but are best conducted with electronic leak detection to identify breaches.
Why Choose Vector Mapping ELD?
Detect leaks through overburden without removing finishes
Identify microscopic punctures and installation defects
Complies with ASTM D7877 leak detection standard
Non‑destructive, precise, and immediate
Ideal for both new builds and existing assets
Common Applications
Green roofs and garden podiums
Tiled terraces and balconies
Ballasted or concealed roof membranes
Planter boxes and water‑retaining structures
