Biobeds are becoming increasingly popular with UK farmers as a means to treat chemical run off from pesticides and other agricultural chemicals, preventing pollution to local watercourses.

Typically used by farmers to prevent contamination from sprayer washings, biobeds provide an ideal solution as they’re easy to create and require little maintenance when in place.

At Cotterill Civils, we supply a range of specialist membranes for biobeds. We can also design, construct and install a biobed to suit your needs and budget. Our installation team has over 25 years of experience in rural construction and are ISO:9001 and ISO:14001 compliant.

What is a biobed?

A biobed is a mixture of peat free compost, soil and straw (biomix) covered with turf that is then placed in a lined pit. They are used as a way to degrade pesticides and stop them getting into watercourses.
