Clay liners are another variety of liner that is used mostly for lining landfills. The material make up of clay liners is a combination of polymeric materials and natural soils (clay). During the fabrication of clay liners a layer of clay is encased between a permeable fabric (geotextiles) or an impermeable membrane (geomembrane). These layers are then either needle punched, stitched or bonded together to increase the structural integrity of the liner.
Clay liners have a very low hydraulic conductivity which means that the rate at which water can move through clay liners is very low which means the effectiveness of the clay liner is high. As a rule the lower the hydraulic conductivity is the higher the effectiveness of the clay liner.
Clay liners are used to protect the surrounding environment by encasing and holding a variety of harmful materials, for example: hazardous waste, landfill materials and waste process water. Clay liners are extensively used in the waste management and mining sectors as they stop leaching through the liner and into the surrounding environment.
All our clay liners meet industry standards and regulations and each clay liner is tested. Clay liners are not suitable for evaporative ponds as these types of ponds leave the lining exposed which will dry a clay liner out.
