Waterproofing Sydney

Penetron Australia provides advanced waterproofing services in Sydney, trusted by builders, engineers, and developers across residential, commercial, and infrastructure projects. Whether you’re working on a new development or upgrading an existing structure, our solutions are engineered to deliver long-term protection against water ingress.

Sydney’s mix of coastal humidity, high rainfall, and dense urban construction demands a waterproofing system that’s proven to perform. Our crystalline technology reacts with water and unhydrated cement to form insoluble crystals within the concrete matrix, permanently sealing cracks and preventing future water penetration, even under hydrostatic pressure.

From basements and rooftops to water tanks and tunnels, Penetron’s self-healing waterproofing technology ensures structural durability, reduces maintenance costs, and extends the service life of your asset. With decades of global experience and local expertise, we’re the waterproofing partner Sydney trusts for lasting results.

“I just wanted to say it was a pleasure working with Penetron on the Genisis Care project for Akalan last year. The solutions you provided were more than helpful and you were always able to get the Penetron product to site when it was required. I also appreciated being able to get you on the phone to bounce ideas off you. I look forward to working with Penetron on future projects.”

“Penetron service and product technical knowledge is unmatched. From the time the project is confirmed through the planning stage, concrete plant supplies and pour day, to after the concrete is poured. The green tracer is a great idea and assurance the product was added by the concrete plants. I would strongly advise the Penetron products and range to any quality builder.”
