Water Puddle Method

The water puddle method allows technicians to identify and locate potential leaks, faults or tears in a geomembrane occurring during installation. It applies a...

Water Puddle method

Project sizes ranging from 20 m² to 253,000 m², totaling 1,409,500 m 2

Average of 6 leaks/hectare on HDPE, PVC and bituminous geomembranes

11 out of these 58 projects had more than 20 leaks/hectare

Out of the 27 projects that had constant third-party CQA on-site, 25 had leaks

Dipole Method

Project sizes ranging from 100 m² to 284,900 m², totaling 1,863,500 m²

Average of 4.4 leaks/hectare on HDPE and PVC geomembranes

6 out of these 75 projects had more than 20 leaks/hectare

Out of the 37 projects that had constant third-party CQA on-site, 18 had leaks

Leak Location General Statistics

More than a third of our dipole projects had at least one large leak (>50 cm²)

The most leaks found on a single project was 203 leaks with the water puddle method and 396 leaks with the dipole method.

Leaks as small as 6 mm² and as large as 12 m X 20 m were located and excavated in evaporation ponds in Chile

In 2014, only 21.41% of all geomembrane installed in the province of Quebec was tested using ELL methods, on which 105 leaks were found

Permanent capping and the water puddle method

Leak location is frequently used on permanent caps to prevent rainwater infiltration, ensuring that confined materials are allowed to dry out, to prevent biogas leaks and to verify the performance of collection systems.

Site extensions and the water puddle method

The electrical isolation of a survey site is much easier to achieve when the site is independent of its surroundings. However, site expansions also often require leak location. Carl Charpentier presents the key steps.
