Nickel mines - New Caledonia

To maintain good stability of the slopes, it is necessary to provide an efficient drain for the stacks. Multi-linear Drainage Geocomposites  DRAINTUBE^® are installed in strips along the slope of the platform, for the dissipation of pore pressure. Lightweight and easy to install, they are not susceptible to creep in compression even under very high loads.

Farmington ponds - NM, USA
75,000 m² (800 000 sq ft) each

DRAINTUBE® drainage geocomposite was selected as a gas collection layer under the secondary liner and a leak detection layer between the primary and secondary liners.

Union Mill pond - Leadville, Colorado
9,000 m² (100 000 sq ft)

In a sodium cyanide-loaded by-product storage facility, DRAINTUBE® drainage geocomposite was selected as a component of the leak detection system between a reinforced polyethylene primary geomembrane and a bentonite geosynthetic (GSB).

South Frazer Perimeter Road, British-Columbia
25 000 m² (250 000 sq ft)
DRAINTUBE^® FTF drainage geocomposite is used for the drainage behind MSE wall in replacement of the washed clean stone layer and the two filtration geotextilesle. The geocomposite offers a stable long-term drainage capacity even under high loads.  The ease of installation of DRAINTUBE^® optimizes construction time and increases safety on site.

Natural sports fields
600 000 m²
The drainage solution DRAINTUBE^® FT has been used to drain and remove excess water from the rootzone during high rainfall events. The solution ensures the drainage of the foundations, which is essential for the successful performance of sports fields.

[Building]

Synthetic and Natural sports fields
600 000 m²
In order to be able to use the sports fields even after heavy rain, efficient drainage of the foundations is essential. DRAINTUBE^® Sport drains the infiltrated water on the entire surface of the field and provides a good separation between the sub-base and the foundation.

Manitoba Mine - Canada
255 000 m²
As part of the rehabilitation of the mine site, DRAINTUBE^® drainage geocomposite was chosen to replace granular resources to collect and evacuate rainwater as well as to limit oxygen infiltration from the final cover.

[Building]

Commercial warehouse building - Edmonton (Canada)
60 000 m²
Rehabilitation of former industrial sites can be subjected to a radioactive gas, radon, which presents a health risk to the occupants. DRAINTUBE GAZ has been used to allow sub-slab depressurization and to prevent radon gas from rising.

[Environment]

Mesa County landfill - Grand Junction (Colorado)
25 000 m²
In order to optimize costs and to have a higher safety factor on the long-term effectiveness of the product, DRAINTUBE^® geocomposite was chosen as a replacement for granular material to drain leachate.
