The technique comprises of recycled hexagonal polypropylene segments, which fit together tightly and float on top of any liquid. Creating a flexible cover on any slurry tank or lagoon, the product, which is heat, frost and wind proof and has a life expectancy of 25 years, also helps to prevent a crust from forming.
If proposals in Defra’s clean air strategy are adopted, covering slurry will be a requirement in England from 2027, and Tramspread says there is currently a lot of farmer interest for the covering.
“Hexa-Cover is popular because it doesn’t require planning permission, professional installation or maintenance,” said Tramspread’s John Tydeman. “We expect to see demand continue to rise as we move closer to the proposed 2027 clean air deadline.”
As a rough guide, a Hexa-Cover for a 20m diameter steel slurry tank takes around two hours to install and costs around £8,000 (includes installation).
