We have recently turned to South Coast Pipelines for all our large bore PE welding and PE fabrication. Tom and the team are highly skilled and have a good foresight and understanding of our project requirements even when we draw it up with a stick in the dirt.

Managing Director | Neverstop Water Group
Select Civil has engaged South Coast Pipelines to undertake HDPE butt welding, EF welding and pipe installation on numerous projects over the last couple of years, primarily with the replacement works of watermains for Shoalhaven Water. We have also used them on some of our Landfill sites for Leachate and Gas pipe infrastructure projects. During this time, Tom and his team have delivered on all fronts. Including helping with the planning and staging of works to having the guys and equipment on site to undertake the work in a very timely manner and also with a very high standard of workmanship. Tom has always gone over and above on all the projects he has done for us and will be our first point of call whenever we have HDPE pipework to be installed.
