Slope Stabilisation

 Application of compost using a compost blower. 

 As part of WRAP’s series of trials using BSI PAS 100 compost, this video shows Cranfield University – working in partnership with Balfour Beatty– using it to control erosion and slope stability. The video shows compost being applied in two ways; first being sprayed onto the slope by an industrial compost ‘blower’ and then being used to fill compost ‘socks’, which are installed at the base of the slope to collect and filter water run off. 

Previous WRAP trials have proven that BSI PAS 100 compost is able to retain water, support the development of healthy plant establishment and growth, as well as reduce the effects of soil erosion. This makes it ideal for use in slope stabilisation programmes, where soil erosion and an inability to support vegetation is a common problem that can lead to slippages – a key concern for highways contractors.  

Although this technology is widely used in the United States, its use in the UK has not yet been fully investigated. WRAP is currently supporting a number of trials which will provide the engineering sector with a vital insight into the benefits of using recycled materials, such as compost, and help them to reduce the costs associated with the maintenance of engineered embankments.
