Waterbar waterproofing flanges were the brainchild and innovation of Bob Moule who developed and patented the Waterbar flanges over 30 years ago. 

  • Bob ran a successful building and maintenance company in Adelaide, and time after time, came across oversized or shattered tap penetrations. He decided there had to be a better way, so worked with a local manufacturer to design perfectly fitting flanges in different sizes.

    When Bob first introduced the product to market, the building trade loved it! It is straightforward to use, no fuss, and most importantly works.

    The days are gone of wasting time cutting out mesh to fit or using endless amounts of silicone to fill the gaps when you use Waterbar Tap penetration flanges! 

  • We are an Australian business through and through and believe in supporting local manufacturers. All products are still manufactured in South Australia, by the original company that helped bring Bob’s dream product to life, so we never compromise on quality. We distribute directly to you via our online store.


    Today the business is run by Verity Moule, she knows everything about the Waterbar penetration flanges and loves it when customers call her with great feedback!

“We have been buying tap flanges from Waterbar for many years. Installation of the flanges is fuss free and quick. They are an easy company to deal with, nothing is ever an issue, the goods arrive promptly. I would recommend Waterbar.”
