Dam Liners

Our Dam Liners are available in 0.3microns, 0.5microns, 0.8microns and 1mm thickness and can be made to suit any size of the reservoir.

We ensure they are heavily protected to make certain no damage occurs during transport.


Our UV treated black damliners are manufactured for tropical climates that experience extraordinary radiation throughout the year. Grekkon Limited’s damliners line the walls and floors of water reservoirs to prevent water loss through sipage into the soil. There is a changing rainfall pattern and unpredictable seasons in Africa, the need for agriculture water conservation is growing amongst farmers.

We factory weld our dam liners which keeps them leak proof during their entire lifetime of use. Leaking is a common occurrence with a manually welded geomembrane. So we only allow it where it is impractical to factory weld.

Grekkon Liners Specifications

Our dam liners are available in 0.5mm, 0.8mm, and 1mm thicknesses. We supply in tailor-made widths that suit the size and shape of the reservoir or tank. Grekkon Limited’s technical team conducts the installation. Then together with the client, we test the installed geomembrane over the next days or weeks to ensure no leakage happens.

To support the liner in a reservoir, the owner does a trench at a distance of 1M all around it. This trench is a foot deep and a foot wide. Once installation within the reservoir is complete, tuck the liner edges this trench and cover. This holds the liner in place during its period of use. For the tank, a steel or wooden band supports the liner in the inner tank’s wall for covered tanks. For the walls of the outer tank for open water tanks.

Knowing the desired thickness

i. The volume of water held. The larger the volume the greater the weight and a thicker liner in place

ii. The wall and floor surface texture. Thicker liners are for rough surfaces
