Innovation case studies

Devised by Hochtief Murphy Joint Venture, in close partnership with Network Rail, this process ensures that piling and diaphragm wall rigs can be used in close proximity to a live railway line.

Ralumac HT was chosen for this scheme due to it being a BBA approved double coat, single pass application. The first coat regulates and seals the existing surface, followed by a second coat using a 10mm aggregate. After compaction and embedment the total thickness of this process was 18mm thick, giving the client reduced levels compared to using a traditional overlay.

The CCTV Pipe Survey Device developed by Murphy enables quick and high-quality surveys to be carried out, saving up to 40% on the costs of traditional methods.

Murphy has utilised this easy to erect and costeffective system developed by Rail Safety Systems to provide a safe working environment close to live railway lines.
