Storage ponds at a tin-mining enterprise

Installation of seepage-control liners for three mine water storage ponds. 

Material that provides complete watertightness and protects the pond base —  a geomembrane, consisting of a smooth polymer sheet made from virgin polyethylene. 

The polymer sheets are laid manually, without the use of construction equipment. The geomembrane is installed with overlaps to create a continuous insulation layer. A hot-air welding machine or handheld extruder is used to weld the geomembrane.

A nonwoven geotextile is laid as a separator between contacting layers and to protect the geomembrane from damage. It is made of polypropylene fibres using the “Spunbond” method and is laid on the prepared base. 
 

• Ease and speed of installation
• Prevention of erosion of the structure’s foundation and slopes
• Non-toxicity and environmental safety of the material 
• Extended service life of the structure
