For tailings and mining applications

Fluid control is critical for most civil engineering applications. The development of pore pressure in soils can compromise the stability of installations. Over the past 30 years, AFITEXINOV has been using DRAINTUBE™ drainage geocomposites to eliminate interstitial pressure and ensure the long term performance of environmental and civil engineering projects. Capillary medium Perforated mini-pipes Diameter of 16 mm, 20 mm or 25 mm These products rely on the combination of various geotextile layers (filtration, separation and protection layers) that are needlepunched together with integrated perforated...

Tailings dam drainage Tailings dams are often built using the upstream method because they are more economical. The limitation of this method is the eventual rise in the water table within the structure, creating stability problems. Safety can be greatly increased through the use of DRAINTUBE™ between built-up sections. Another issue in mining operations is the management of sand and its’ storage using dikes. To ensure total safety of work sites, the stability of these dikes is a central design challenge. The saturation rate of sand and the slopes are thus controlled, and depend on the nature...
