Special sensors are installed under the geomembrane liner during construction of the containment site.

The impervious geomembrane liner is not intended for long term seepage control.

Both leak detection techniques utilize the insulative properties of geomembrane liners.

The minimum sensitivity of the arc testing bare geomembrane liner integrity method is a pinhole leak.

Any geomembrane liners used shall be completely removed and shall be disposed of as construction waste.

After completion of construction and testing for damage and repair as required, the geomembrane liner is certified to be "damage free".

Typically, each pad only has a single, geomembrane liner for each pad, with a minimum thickness of 1.5mm (usually it is thicker).

The company's market position as the largest manufacturer of geomembrane liners, its global manufacturing and distribution capabilities, and relatively stable end markets partially offset these factors.

A starter dam is to be constructed to a height of 152 m comprising mined waste rock with a bituminous geomembrane liner on the upstream face.

The relatively thin Geomembrane liner (typically 2mm thick) cannot be laid against the rough quarry face without the risk of it rupturing during the compaction of the waste.

Extensive remediation was then undertaken, including the installation of a 45 mil scrim-reinforced geomembrane liner covering the site of the trenches to prevent the infiltration of water.

Consideration is then given to the vertical expansion of existing landfills and finally to the modelling of the finite service life of a primary leachate collection system and geomembrane liner.

In addition, the use of HDPE geomembrane liners in potable water reservoirs conserves millions of tonnes of water annually by preventing seepage loss.

Geomembrane Liners & Floating Covers Fabric Solutions are specialists in the field of engineering, fabricating and installing geomembrane liners.

Contaminant modelling of the entire lagoon liner suggests that the geomembrane liner most likely stopped being effective as a contaminant barrier to ionic species sometime between 0 and 4 years after the installation.

As evidence of this long life, a Nyex 0.75mm PVC geomembrane liner was recently exhumed from the bottom of a highly alkaline tailings dam where it had been installed for 18 years.

The technique also allows modelling of the finite service life of engineered components of the barrier system such as the service life of the primary leachate collection system and, if present, geomembrane liner.

Liners for Liquid containment shall comprise an appropriate one-piece liner that will prevent leakage from the containment area, which liner as a minimum shall be a geomembrane liner not less than 1 mm thick and acceptable to the Owner.

A Coletanche bituminous geomembrane liner was proposed instead because it meets the rupture criteria for the anticipated working load of five MPa; has a better longevity than highdensity polyethylene; and meets all the constructability constraints expected at Galore Creek.
