DAM Liners for Heavy Industry in Australia: Advancing Environmental Sustainability

The heavy industry sector in Australia, such as mining, oil and gas, and agriculture, has a significant impact on the environment. One of the most significant challenges in these industries is managing the storage and containment of liquids and materials, such as chemicals and waste products. The use of digital asset modeling language (DAM) liners is an innovative solution that can enhance environmental sustainability by improving the storage and containment of hazardous materials.

DAM liners are high-quality, flexible barriers used to contain liquids and materials in heavy industries. They are made of various materials, including reinforced polyethylene, PVC, and geotextiles, which are resistant to chemical exposure, punctures, and tears. DAM liners are ideal for lining ponds, lagoons, and other containment areas in heavy industries, providing a safe and secure solution for storing hazardous materials.

In the mining industry, DAM liners can be used to line tailings dams, leach pads, and other containment areas. This helps to prevent the release of hazardous materials into the environment, protecting the ecosystem and wildlife. DAM liners can also reduce water usage by preventing water loss through seepage, thereby conserving this precious resource.

In the agriculture industry, DAM liners can be used to line irrigation channels, ponds, and reservoirs, helping to prevent contamination of the water supply. This helps to protect the health of humans and animals, as well as the surrounding environment.

DAM liners are also widely used in the oil and gas industry to line storage tanks, pits, and containment areas. This helps to prevent spills and leaks, protecting the environment and reducing the risk of fines and legal action.

In conclusion, DAM liners are a vital solution for heavy industries in Australia, advancing environmental sustainability by providing a safe and secure way to store hazardous materials. By incorporating DAM liners into their operations, heavy industries can help to protect the environment, reduce water usage, and maintain regulatory compliance, contributing to a better future for all.

What Kind of Dam Liners We Should Use for a Pond

We are often asked what kind of liner we should use for a pond. The answer is not simple. There are many variables:

  • What is being stored? What is the PH of the liquid being stored? This will determine the type of polymer that is to be used if indeed a polymer is suitable at all. Liner manufacturers produce chemical resistance charts – these should be consulted.
  • Once the chemical compatibility is determined then we can decide what thickness of the liner is to be used. The thickness will be determined by the condition of the subgrade (How many rocks and what size and shape) and what life is required from the liner. The thicker the liner the more resistance there is to subgrade conditions and the longer the life in the sun. Resistance to rocks in the subgrade can be increased by the use of geotextile under the liner. It has been shown that a geotextile will act compositely with an HDPE liner to give better performance. HDPE is provided with antioxidants and UV stabilisers in its composition. The antioxidants are provided to give protection against oxidation during the manufacturing process and long term. The UV stabiliser is usually carbon black.
  • What colour liner. White liners expand less in the sun than black liners and produce smaller ripples when heated up. If the pond is an evapouration pond and is to be empty some or most of the time then the use of a white liner should be considered.
  • The batter slope and length will also have an effect on the type of liner. Where the batter length is long then the use of a rough-textured liner should be considered to give added frictional restraint to the sub-grade.

Liner type and thickness and configuration is a science on its own and has been the subject of extensive research. When making the call on a liner type consult someone with a background in the subject.

GDT Lining Systems have recently completed the construction of a Molasses Bladder Molasses generates CO2 and H2S when stored. Molasses often enters the storage hot and cools of emitting gas as it loses heat. If the gas is not removed from under the cover it will interfere with the roof drainage which may cause the gas flow under the cover to be blocked and large bubbles in the cover system to form.

A large central float with a gas collection pipe system on either side provides positive extraction of the gas by way or an inline industrial fan. Application of a small negative pressure under the cover has a big effect, pulling the cover down against the stored molasses and allowing water that is collected on top of the cover, from precipitation, to find its way to the perimeter drainage sump. Provide perimeter rather than central weights to the system.

GDT has been installing molasses storages for 30 years and has learned about the problems of gas produced.

GDT Lining has a mission to improve the industrial landscape by containing any harmful waste. We accept that waste is a biproduct of our industrial society. We aim to mitigate the downside to a level that is acceptable, by limiting the spread and effect of waste materials on everyday life.
