Improvement of the leisure facilities at Aylestone Hill by Herefordshire Council included development of community football and cricket pitches, a bowling green, and access to parking. The Herefordshire and Gloucestershire canal runs along the * border of the site and had become backfilled with silts contaminated by hydrocarbons and metals. Celtic was contracted to provide a sustainable remediation solution to the issue, provided by stabilisation / solidification of the dredged sediments to both mitigate the contamination risk and provide geo-technically suitable material for use below the car park and access roads.
