Here are just some of the reasons:
All concrete is vibrated and mixed to over 40 MPa and poured at 80 slump, we also use both Dribond Chrystalis and Glenium 8100 plasticiser to keep up the strength in the tanks (instead of water) and after 28 days of curing the strength of the concrete will be between 48 and 52 MPa.
The base of the tank needs to be flat, preferably laser leveled, with 170 mm of compacted road base – no fill. Remember these tanks are very heavy. With the largest tank 27 cubic metres of concrete is poured. The site for this tank needs to be at least 11 metres in diameter as this tank is 8.6 metres wide. There needs to be room for the scaffolding to be built up and the formwork to be laid out.
With our tanks all brass fittings are supplied and as many as required to fit your personal requirements. You cannot see pour marks nor air bubbles in the walls. By using 40 MPa (not 25 or 30) the tanks when dried are white, not dull grey, and this is a sign of the strength in the tanks.
We comply with the Building Code of Australia, B1 Structural Provisions and the Australian Standards Code AS 3600 for Concrete Structures and AS3575 for retaining liquids.
Concrete water tanks keep your water cool under all conditions, are algae free and last for many, many years. They will not rust, or burn or melt nor blow away, the water will not taint nor are there any inside liners to be replaced. And remember a decent concrete water tank adds value to your property!
The floors of the tanks are sloped into a 75 mm (3″) drain plug for above ground tanks and a sump for below ground tanks, which enables the tank to be cleaned out thoroughly. And all required brass fittings are included in our price.
We can also supply at an additional fee safety ladders and platforms.
Terry specialises in building concrete underground tanks, and we have built hundreds over the past few years.
The largest of our heavy duty industrial concrete underground tanks will weigh approximately 78 tonnes when empty and you will be able to drive and/or park a truck on top.
We build these tanks with either six or eight support legs. With these support poles the roof of this tank will take up to 20 tonnes in load bearing weight and/or can take up to one metre of dirt/fill. We individually vibrate each leg in the tank to ensure the concrete is properly mixed. This is a very strong tank. You can use the top of the tank as a patio or bbq area; bury the tank completely or park your car on top! We use F92/F102 mesh in the roof of this tank, and Y12 starter bars in the base of the tank, which is why they are so strong.
