Welcome to Plastek: Australia's Premier Poly Tank Manufacturer

At Plastek, we understand the unique challenges posed by the Australian climate. That’s why our rainwater tanks are engineered specifically for Australian conditions. Built tough to exceed Australian standards, our tanks are designed to be worry-free, once installed, our tanks just do what they’re supposed to do. So you can too!

Why Choose Plastek Rainwater Tanks?

Wide Range of Capacities:

Our tanks come in a variety of sizes to suit any need, ranging from 335 litres to 27,250 litres.

Self-Supporting Roof Design:

All our tanks feature self-supporting roofs, eliminating the need for a centre support pole. This design choice not only simplifies installation but also addresses occupational health and safety concerns associated with confined spaces.

Advanced Algae Prevention:

Select tanks are equipped with a UV cover under the leaf strainer to block sunlight, preventing algae growth and ensuring cleaner water.

Compliance with Australian Standards:

Our polyethylene material meets the rigorous Australian standards AS2070 (food grade) and AS4020 (drinking water), ensuring your water is safe for consumption.

UV Stabilised:

Built to withstand Australia’s harsh sun, our tanks are UV stabilised to prevent degradation from prolonged exposure to sunlight.

Aesthetic and Durable Finish:

Featuring a unique textured finish, our tanks blend seamlessly with the environment, avoiding the glossy plastic look of other tanks. A corrugated profile option is also available.

Robust Construction:

With the maximum shot weight of plastic material, we guarantee ample wall thickness for durability. The walls are specifically thicker at the bottom to provide maximum strength where water pressure is greatest.

Superior Mould Design:

Our tank moulds are meticulously designed to separate at the top, ensuring the part line is positioned in the least stressed area. Unlike poorly designed moulds with parting lines down the sides, our tanks avoid weak areas that could cause splitting.

Rigorous Testing:

Plastek tanks undergo thorough in-house testing, including ultrasonic thickness measurements and impact testing, to ensure they meet our high standards of quality and durability.

Longevity:

Using Finite Element Analysis, we predict a 25-year lifespan for our tanks, offering long-term peace of mind for our customers.
