Fibreglass
Tanks

Stronger. Lighter. Better.

Not all tanks are created equal

Septic, rainwater, and detention tanks should be built for the long-haul. But many tanks on the market crack, leak, and fail under pressure, leading to costly replacements, delays, and compliance headaches.

Why settle for less?

Do you need a dependable and durable tank that won’t crack or corrode?
Tired of long and labour-intensive installations that inflate your costs?
Looking for a lightweight, heavy-duty solution that minimises man hours and makes transport easy?

Hear from our clients

Well done in bringing this product to the market

Hi Rob. Just wanted to pass on how pleased I am with your tanks. You have bridged the gap with a product that addresses the problems with the light weight poly products and the heavy concrete tanks. You have a brilliant design that will not split or distort as the poly tanks do or delaminate in a corrosive or acidic environment that will destroy any concrete tank. They do not need any heavy lifting equipment to install or transport and have a riser system that can be adjusted to suit the ground level perfectly without the need to position the tank to suit this. A truly brilliant product that will give years of service. Well done in bringing this product to the market. Kind regards, Wayne

Phil Wilkinson Plumbing and Gas Fitters have been installing the septic tanks and tank riser and lids for around 10yrs

Phil Wilkinson Plumbing and Gas Fitters have been installing the septic tanks and tank riser and lids for around 10yrs. These products whether it’s 3,000 or 30,000 ltr tank you need or just the riser they can do it. The risers are fantastic, lightweight yet very strong, sturdy and well made, these can be installed at any depth. The unit is a once buy, you’ll never have to dig it up again and unlike the concrete alternative, is level with the ground and does not need 2 men to safely lift the lid. It’s a no- brainer get it done today!

The saddle and riser worked out perfectly

The saddle and riser worked out perfectly. Easy to put in place – a brilliant design in it’s simplicity. I’m very happy that I came across you online. The pump out boys (Alexandrina council) we’re seriously impressed too – I’m guessing they’re hoping a lot more people put them in place too (save their backs)!
