A big hole in the ground

When the staff at the brewery Hancock A/S arrived at work in September 2008, they saw a rather strange sight. At the parking lot, there was an almost two-metre-deep hole. They could only guess the reasons for the hole. They did not know. But the next day when there was sewage water in the basement, the management at Hancock sensed that the situation was a serious one. A local contractor was called in, and he stated that the problem was a collapsed sewer pipe.

After a couple of weeks, the extent of the renewal – or rather the potential extent – became clear to the management at Hancock. It turned out that significant parts of the pipe system ran under the brewery. The management contacted Aarsleff who first relined the damaged pipe under the brewery. This work was started on a Friday in order to avoid interruptions in operation. The next step was an extensive CCTV inspection of the entire pipe system which turned out to be worn out.

After careful consideration, the management chose to let Aarsleff reline the pipes that were found under the buildings, while the pipes outside were renewed. Within the first eight days, Aarsleff made access to a hidden manhole under a big storage tank and renewed three sewer sections at a depth of 6-7 metres under the brewery. 

It was very important to both the management and to Aarsleff that renewal of the pipe system could be done with the least possible interruptions in operation. According to the management at Hancock, the extensive renewal work that was carried out directly under the production facilities by means of Aarsleff CIPP Lining did not influence the quality of the well-known Hancock beer whatsoever.
