2016 The Vines, Mills Reef Winery, Tauranga Weld drill and install 120m of 900mm OD HDPE for the Vines Subdivision, in the Mills Reef Winery, a straight forward instillation for our team and the American Augers 440DDT. This pipe line was 14m deep and with a grade of 3.3%. Project completed on time and in budget with additional work of destructive testing and flanges. Our recycling machine was very effective - reduced dump costs and cartage of greater amount of drill slurry, associated with larger pipes. Mills Reef-Classic Developments
