Products Advantages
Advantages of dam liner
-Reduces Seepage at Reasonable Costs
Since the pond liners are impermeable geomembranes made of synthetic materials like plastic and rubber, it is extremely potent at retention of liquids. This is extremely helpful in regions that face frequent droughts. Since most types of pond liners even for large ponds are affordable, the cost involved in retaining water is quite reasonable.
-Highly Durable with Chemical Resistance
Pond liners based on HDPE (High-Density Polyethylene) are largely non-reactionary to chemicals. They are also highly resistant to the UV rays from direct sunlight, preventing any chemical reaction. Large pond liners are huge in size and thickness, which make them extra strong in keeping tears and punctures at bay. This non-reaction to chemicals, and high durability make keep the water usable for long periods.
How to choose the suitable Dam liner?
size of the dam or pond
exposure to UV
required dam liner life
preparation and nature of the base of the dam
available budget for the dam liners
Liquids that are contained may be drinking water, industrial process waste such as dunder or mine washings, sewerage or molasses.
Dam liner
Products Application
The subgrade that is to receive the dam liner requires careful preparation.
The subgrade materials are dispersive and this interferes with the end-use of the water.
Liquids other than pure water are stored and it is required to minimise the escape of the contained liquid. An example of this is sewerage effluent where the entry of small amounts of pollution into subterranean water supplies may have health implications for downstream users.
It is required to minimise erosion on the pond embankments. Erosion may be caused by the impact of rain or by the effect of aeration or mixing equipment within the pond. An example of this is the use of lining systems on prawn grow-out pond embankments to minimise the entry of suspended sediments into the pond and the associated increased risk of disease and crop loss.
