Floating cover for slurry reservoirs

Genap offers a durable solution for slurry reservoir coverage with a floating cover crafted from reinforced PVC geomembrane. This material boasts remarkable resistance to slurry’s corrosive properties, extending the lifespan of the cover. It’s essential to pump away rainwater gathered on the cover to prevent undue stress on the material and to possibly enhance the reservoir’s effective volume by as much as 30%, depending on precipitation levels. This approach ensures compliance with the Netherlands’ mandatory covering regulations effective since 2018. Installation of mixing hatches, access ports, and specialised floats for venting gases is conducted on-site during setup.

Replace the floating cover in time

Factors such as UV exposure, climatic conditions, and physical wear may lead to the degradation and eventual tearing of floating covers. Conducting periodic inspections allows for their timely replacement. Although replacing the cover on an empty reservoir is preferred, we are equipped to perform this task on a full reservoir as well. The removal process for an old floating cover also presents an opportunity to inspect and, if necessary, replace the reservoir’s base liner simultaneously. Comprehensive pre-service advice ensures you’re fully informed of the required tasks.
