Ferro Monk Systems, part of the Clugston group of companies and one of the UK’s leading wastewater asset and pipeline rehabilitation specialists has recently completed a successful project on the Hendon Brook Walverden Water Flood Alleviation Scheme Phase 1. The project which was successfully completed on time and on budget involved using two of the company’s solutions, Cured in Place Pipe Lining (CIPP) and the company’s own patented Ferrocement solution. Ferro Monk is one of the very few companies in the UK capable of providing this range of solutions on projects of this nature.

Working closely together with Jacobs Engineering UK Ltd, the consultant engineer on the project, and the Environment Agency, who commissioned the work, the company established the most cost effective, best suited and timely solutions to tackle the problems at Hendon Brook.

The project, which lasted a total of four weeks, required a series of complex phases to be completed. CIPP was used to three culvert sections, each of which had its own unique requirements and involved lining corrugated steel pipe as well as clay and concrete pipe. All the sections were successfully lined with bends negotiated smoothly and minimal loss of cross sectional area, resulting in a much improved flow characteristic due to the smoothing effect on existing corrugations.

A final culvert, beneath Leeds Road in Nelson, which had failing brick problems, was too large to be lined with CIPP. In this instance Ferrocement structural lining was used to the side walls and arch. To successfully complete the work, the culvert had to have significant levels of silt and debris removed by man entry teams in advance of any rehabilitation.

Mr Ian Gemmell, Contracts Manager, from Morrison Construction commented, “Ferro Monk Systems provided not just one solution but two, with CIPP and Ferrocement. The senior team involved objectively looked at the requirements of the project identifying what was required and delivered on time and on budget what was a perfect solution. We were most impressed with the outstanding professional service and support we received.”
