The generation of unwanted waste materials is an unavoidable feature of many industrial processes. Envitech has a proven background in the development and installation of cost-effective strategies to minimise the potential for pollution. These strategies include the design of lining or capping systems using a variety of geosynthetic materials and geo-composites. This reduces the potential for environmental damage and therefore lessens the risk of any associated liabilities.

We offer a proven capability in the following key areas:

• Landfill liner systems, including double liners, geocomposite liners, leakage detection systems and the design of leachate management systems.
• Closure and rehabilitation of landfills and tailings dams, including the design of capping systems incorporating geomembranes and geosynthetic clay liners (GCLs).
• Effluent, hazardous waste and chemical liquid storage lagoons, a comprehensive service covering the design of lining systems including chemical and environmental compatibility testing of all lining materials.
• Pollution control dams and silt traps for the management of dirty or contaminated process water or stormwater runoff.
• Heap leach systems for the mining industry, including the design and supervision of installation of lining systems for the protection of sensitive groundwater resources.
• Irrigation dams in agriculture for centre pivot irrigation systems.
• Construction Quality Assurance (CQA), including compilation of CQA plans, construction monitoring and contract administration for the installation of lining systems in accordance with SANS1526 and SANS10409.
