Case study: mining culverts

Subway Rochdale, UK..

Benefil was the system of choice for Rochdale Borough Council and Mouchel Parkman’s Impact Partnership when considering methods for filling a redundant subway near Rochdale Town Hall.

“We chose Benefil because it was a lot easier than using concrete or granular fill,” explains the Borough Council’s Senior Engineer, John Ashley. “If we’d had concrete, for example, there are access problems and multiple deliveries would have been necessary. Plus if you pump in concrete you have to top it off and grout it up and so on. Benefil is a one-hit wonder.”
