Application

One of the most common geomembrane applications is as a pond or dam liner. Pond liners may be used where:

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.

The type and thickness of material in dam liners vary. The main determinants of the type of material to be used are:

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.

The subgrade that is to receive the liner requires careful preparation. The subgrade preparation is required to meet the specification of the liner manufacturers. Failure to meet these requirements may result in the invalidation of any offered guarantees. Typically the embankments are required to be regular and free from sharp or large rocks. Material placed in contact with the liner is required to be less than 10mm in size. Where granular material forms the subgrade it is usual to place a geotextile under the layer. The geotextile used is usually a needle punched, non-woven material with a weight of not less than 250gms/m2.

Where ponds are to be constructed in areas where there is vertical gas movement through the subgrade of the pond then it is required to provide a subgrade venting system to prevent gas from collecting below the dam liners. Vertical gas movement may be produced by the movement of the water table over a seasonal or diurnal period or by the degrading of vegetation matter at depth. The venting system usually consists of a full geotextile layer underlayed by a herringbone system of slotted pipe or slot drain wrapped in geotextile. The venting system may fulfil a dual role. The system can double up as a leak detection system and can also be used to monitor the level of the groundwater before the level of the contained liquid is reduced to minimum levels.

Lining materials for ponds include HDPE, Polypropylene, Elvaloys and PVC.

The most widely used lining systems are HDPE, which is produced in various thicknesses and textures. HDPE is delivered in 7m rolls weighing approximately 1.6 tonnes. The material is unrolled and welded on-site with wedge and extrusion welding equipment.

Lining systems are anchored at the perimeter of the pond by either burying the upper edge or by fixing the perimeter to a concrete anchor beam.

Features & Benefits

- 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

FAQ

1. How long does an HDPE liner typically last?
An HDPE liner can last for up to 50 years or more, depending on the application and environmental factors.

2. What is the installation process for an HDPE liner?
The installation process for an HDPE liner typically involves excavating the area where the liner will be installed, laying down a layer of geotextile fabric, and then placing the HDPE liner on top. The edges of the liner are then anchored to prevent movement.
 

3. Can an HDPE liner be used for potable water storage?
While HDPE liners are commonly used for storing water, they are not typically used for potable (drinking) water storage. Specialized liners are required for potable water storage to ensure that the water remains safe to drink.

4. What is the cost of an HDPE liner?
The cost of an HDPE liner varies depending on its thickness, size, and other factors. However, HDPE liners are generally considered a cost-effective option compared to other types of liners.

5. What are the specifications for HDPE geomembrane used in gold mining heap leaching liner?
The specifications for HDPE geomembrane used in gold mining heap leaching liner vary depending on the specific application, but typically include thickness, permeability, and chemical resistance.
