About Us

Tank Services

What We Do Best

Our Services Comply With Australian Standards (AS3740 - Waterproofing of Wet Areas in Residential Buildings, AS4858 - Wet area membranes, AS4564.1 - Waterproofing membranes for external above-ground use, AS4020 - Products for use in contact with drinking water.)

Metal Tank

Metal tanks are prone to rust, corrosion, and leaks over time. Unlike bladder systems that hang inside the tank and can trap moisture, accelerating rust, our advanced sealing system adheres directly to the tank substrate. This stops rust in its tracks, prevents leaks, and provides long-lasting protection.

Read More

Panel Tank

Panel tanks often rely on bladders, but these can trap moisture between the bladder and panels, causing rust and accelerating the tank's deterioration. Our solution is different. Using a potable, non-toxic, eco-friendly product, we create a flexible, seamless membrane that adheres directly to the tank's surface. This waterproof barrier prevents leaks and rust, protecting your tank and extending its lifespan.

Concrete Tank

Concrete tanks are prone to cracking due to fluctuating water levels, which can cause the cracks to expand and lead to leaks. Over time, the steel mesh inside can rust, compromising the tank’s strength and longevity. Our seamless system is specially designed to adhere directly to the concrete surface, creating a durable, waterproof barrier that prevents leaks and protects the tank’s structure. Made with potable-safe, non-toxic, eco-friendly, and flexible materials, our products ensure a long-lasting, reliable solution for your tank.

Have Any Questions

Liquid rubber is a safe, eco-friendly solution for tank sealing and waterproofing. Its water-based formula contains no harmful solvents or volatile organic compounds (VOCs), ensuring a non-toxic application. Designed for durability, it adheres seamlessly to the tank surface, creating a strong, waterproof barrier. Most importantly, it is **potable safe**, meaning it’s certified for drinking water storage, making it a reliable choice for residential, commercial, and industrial tanks.

Yes! Our liquid rubber system is designed to adhere to a variety of tank surfaces, including metal, concrete, and panel tanks. It creates a seamless, waterproof barrier that prevents leaks, rust, and deterioration, ensuring long-lasting protection for any type of tank.

No, you don’t have to do anything! We take care of the entire process from start to finish. Our team will empty the tank, thoroughly clean it, and apply the liquid rubber coating. This ensures the job is done correctly, providing the best possible finish and long-lasting protection for your tank.

We recommend waiting 1 to 2 weeks before filling your tank, though the longer you wait, the better. This allows the seamless membrane coating to fully adhere and dry to the surface, ensuring maximum effectiveness and durability before the tank is filled with water.
