Meales Concrete Pumping were contracted onsite to complete a new technique of securing the plastic liner on the bottom of the Sediment Pond in Cell 2.

The technique involved pumping a flowable fill grout mix into individual pillows that are roughly 10m x 4m and hold around 10m3 each.
We had our 47m boom and 40m boom onsite fulltime pumping a total average of 300m3 per day. Most days required roughly 100m of additional pipeline on the end of the boom to reach each segment.
We had 8 men living onsite that were on a 2 week rotation. Stirling Mawby from the Brisbane branch co-ordinated and established the procedures to get the job completed efficiently and within Ostwald’s requirements.

Mid July 2013 saw the completion of the concrete shell on Tank B at QCLNG (Queensland Curtis Liquefied Natural Gas project), which is being constructed by Bechtel Australia on Curtis Island, Gladstone. These tanks are 90 metres in diameter and 40 metres in wall height plus the roof. In total approximately 15,000m3 metres of concrete has be poured in Tank B, with the final roof structure being poured in 5 consecutive days and a total of 2500m3 of concrete placed on the roof over these five days.  With the use of 3 x Putzmeister MX42 metre placing booms and 3 x Putzmeister BSA 2109 High pressure trailer pumps the entire concrete pouring process has been hassle free, and stream lined due to a great team effort between Meales and Bechtel management.
