Propump helps to eliminate bottleneck

Propump Engineering Ltd has been commended for its work on the Thameslink Borough Viaduct in London. Contracted by Skanska, 400m3 of foamed concrete from Propump was used to infill arches under the historic shops at Green Dragon Court and the basements beneath the roadway at Railway Approach.

When complete in autumn 2012, the new viaduct will complement the existing one over Borough Market and eliminate the bottleneck which currently requires all Thameslink and Charing Cross train services to share the same tracks. In the future, each of these services will have dedicated tracks, allowing for improved reliability and punctuality.

To fill the voids in the ground a free flowing self compacting material was required. Lightweight and self compacting, Propump manufactured the foamed concrete on site via its super efficient In-line Foamed Concrete System (IFCS), which enabled the material to be pumped through the cramped working conditions on site. Accurate volumes of material were produced to match the contractor’s expectations and therefore budget constraints.

Propump’s service and compliance with the strict vehicle movement controls imposed due to the sensitive nature of the site led to a commendation. “We were very happy with Propump’s work and technical capabilities,” said George Harisis, Commercial Manager at Skanska. “They were the most competitively priced and we would absolutely use them again.”
