BRAWOLINER HIGH-TECH LINING SOLVES VERTICAL DOWN PIPE DILEMMA IN CAMBRIDGE CENTRE OF LEARNING

The university city of Cambridge is famous around the world not only for the calibre of its educational institutions but also for the classic nature of its architecture. However not all the buildings in the city are as old or as classical as the University. In the 1970s one building was constructed, now a Grade II listed building, comprising a three-storey structure. The building was designed to compliment the surroundings and as such was built with a series of soil vent and rainwater down pipes, all made of copper piping, located within the confines of the structure. Over the years since its completion the building has been subject to the usual vagaries of weather etc and in recent years these downpipes have shown signs of deterioration. In some instances the pipework was found to be leaking causing water damage within the building.

UV LINING AIDES MAJOR POWER STATION RENOVATION WORKS

AES Kilroot Power Station (KPS), near Carrickfergus, some 12 miles northeast of Belfast, is an oil and coal burning power station that produces around one third of Northern Ireland’s electricity. Being such an important power generator for the area, however, the current facility must be kept at its best efficiency and operational performance at all times. As part of the ongoing maintenance work to ensure this performance is achieved, a CCTV survey of the existing 420 mm diameter, steel, sea water pipelines which have been in use for over 30 years was undertaken. The survey showed signs of severe encrustation and corrosion, with, in places, up to 30% of the pipe cross section being obstructed. Corrosion had also removed a length of approximately 7.0 m in the invert of one pipe and there were also numerous small holes throughout the length of the pipes which allowed the ingress of water in the form of jets and seepage.

UNIVERSITY OF EAST ANGLIA – SEWER CLEANING AND LINING PROJECT WITH MC BUILDING CHEMICALS

As part of a corridor link and long term maintenance project, Norwich-based utility consultant Kier Eastern (part of the Kier Group) recently undertook a programme of sewer cleaning and lining work on behalf of University of East Anglia (UEA), under the direction of Tim French. The contract to complete the necessary work was awarded to Dyno-Rod of Mahoney Green, Rackheath, Norwich, with lead project engineers J Vaughan and S Plane. The work was to be undertaken beneath the Sainsbury Centre for Visual Arts, part of UEA, a prestigious and well known building in Norwich and comprised the rehabilitation of existing cast iron pipe work, which was in a poor condition and in many locations, badly pitted and corroded. Dyno-Rod advised that the most sensible and practical solution would be to Dyno-Line the existing drainage pipe. The works were undertaken as part of the overall improvement and refurbishment of the Sainsbury Centre. The work would result in a new pipe within the old damaged pipe, which would be resilient to ground movement, impervious to leaks or root penetration, and which offers minimal cross-sectional loss (and therefore carrying capacity) whilst increasing hydraulic efficiency. The lining is also guaranteed for 15 years.
