About Us

We offer a full range of Geomembrane Liners and Covers for almost any conceivable purpose

Company founder Max Brady purchased Warwick Tarpaulins in the early 80’s. In 1983 Max moved his operation from Warwick to Toowoomba and established Darling Downs Tarpaulins “DDT”. Through the Darling Downs Tarpaulins business Max was exposed to the endless possibilities that geosynthetic products provided to a large variety of industries. After pursing this interest for over a decade, Max established DDT Liners in 1995. DDT Liners was established with a

clear focus of providing geosynthetic solutions at commercially viable rates whilst maintaining the highest level of quality possible. Our current Managing Director Chris Riding joined Max’s team in 1994 and has been spearheading our activities for the last decade.
