MaxiFlow 1800 Crossings

A Single-Piece Design Bridge Culvert for High Water Flow

When you need maximum water flow for serious irrigation applications, our MaxiFlow 1800 Crossings are the perfect bridge culvert solution. Our unique, patented single-piece design (with headwall, arc and base) have been transforming farms across Australia for the past 30 years.
Our unique flat-bottomed design is incredibly fast and easy to install, just lay them straight down for effortless levelling. You’ll achieve flow rates of between 40ML to 80ML per day, the equivalent to a 1150mm round pipe.
Our culverts are tough and built to last and won’t allow any silting to occur.
With 2.3m sections, you’ll be able to customise these to just about any length that your farm layout requires. Our team of irrigation specialists are always on hand to help you customise our products and systems, so they suit you.
