Floating covers are geomembrane systems that provide a floating sealed cover for both hydraulic engineering and environmental applications.
For the former, floating cover helps prevent evaporation and protect content such as potable water from external agents (e.g. suspended particles, contamination, organisms, algae)
For the latter, the floating cover can help eliminate odours, mitigate the emissions of gases that pollute the atmosphere or simply create a biological reactor to capture gas for subsequent processing and use.
Materials for floating covers must provide mechanical strength, as much dimensional stability as possible to accommodate temperature cycles and flexibility to accommodate repeated changes in the water level or waves and stresses caused by wind throughout the full service life.
These requirements mean that a reinforced product is normally used, although innovation in materials means there are now products that can offer these properties without the need for a reinforcing mesh. Atarfil can supply all these high-tech materials. Please contact us for further information.
It is also important to ensure that the geomembrane offers suitable chemical resistance for the application.
