About Us

About Us

Established in 2004, our company is now widely considered one of the largest and most progressive waterproofing businesses in Western Australia.

We are West Australian owned and are actively run by the Managing Directors, Mary-Lena Goss, Michael Goss and Dominic Whalen.

We are focused exclusively on the expanding Western Australian building market and on leading with new and advanced technologies.

To complement our extensive array of services we have a dedicated team of administration specialists consisting of Estimators, Quality Assurance Managers and Project Managers. This provides our many builders with the confidence in knowing we provide them with a professional and competent management team.

We have built a reputation for being a highly skilled group of professionals and we have been able to build on our reputation of being the preferred contractors to the majority of Western Australia’s First Tier construction companies.
