Midland Links Projects

Our first midland links project, R9, was carried out in 1990 and since then we have been a vital part of numerous contracts on the area 9 partnering scheme. During 2010 we worked on three projects simultaneously, R157, R161 and College Road and managed to deal successfully with the heavy workload and fast changing nature of these contracts. At present we are working on the R153 which is a relatively small job and are due to commence work on the much larger R165 in the coming months. 
The Midland Links projects are always demanding but also extremely rewarding. The programme of works can change daily meaning flexibility is a must, and the removal of the concrete is hard work for even the most talented operatives. It is our experience of completing these projects that has formed the ethos of the company, which is that we will always try to help our clients in any way we can, and has also enhanced the ability of our workforce who are now ready to tackle any type of removal.

A1260 Bridge Structures Project

Below are details of one of our projects, we have further examples of our other projects to come!

The work on the A1260 was carried out for Osborne and completed by the end of March 2011. The challenge was to remove 245m3 from 12 piers in the shortest time possible. Due to the nature of the project we were competing with different methods of removal at tender stage and we had to ensure that our proposals were both cost effective and able to meet the demands of the programme.

On each pier there was 20.46m3 to be removed and we set ourselves the timeframe of 4 No 24hr periods to complete this. This meant operating with two crews during the day and two crews during the night.
Unfortunately there was no water supply available at any of the piers, which would have been a major problem had we not been able to use our tanker units to both jet with and as static tanks. We then arranged for a local contractor, IWJS, to collect and deliver water into our tanks throughout the day and night shifts to allow us to jet continuously for 20hrs per day, only stopping to allow clear up of the huge volumes of concrete being removed.
During the first phase of 6 piers we encountered a few teething problems similar to any that occur on a project of this magnitude. We also had to work through freezing conditions with temperatures dropping to minus 14 on site, which is obviously not ideal for water jetting. Despite the difficulties we were able to complete the first phase on programme and leave Osborne extremely satisfied with our performance.

When the second phase began we knew that we would be able to comfortably meet the programme and we therefore reduced the number of jetting crews to three. We also managed to reduce the time taken to complete each pier to 3 No 24hr periods as the freezing weather had subsided and everybody on site knew what was required for the job. The second phase was completed successfully over a 5 week period.

Water Jet Concrete Cutting

One of the reasons for the popularity of water jet concrete cutting is that it meets even the strict environmental laws. It generates little dust due to the use of water, as there is no metal edge to sharpen, and no heat or spark generated during cutting. There are also no finishing steps required as the cut produced by the water jet is perfectly fine.  The forces involved make the use of water jet cutting with robotics possible.

Water Jetting

Water jetting involves pressurizing water to mega high pressures which then form an intense cutting stream To achieve these pressures, water is introduced into the unit via a booster pump and filter visit us online to find out more about water jetting and the water jetting services we provide please visit us online at
