At Flexitank Systems, we understand that choosing the right liquid storage solution is an important decision. Whether you’re considering bladder tanks, steel tanks, or corrugated reservoirs, we’re here to help. Below, you’ll find answers to the most frequently asked questions about our flexible liquid storage solutions, including installation, maintenance, and usage. If you need more information, feel free to contact our expert team for assistance.
Sectional panel tanks are used for storing water and other liquids in various industries, including residential, commercial, industrial, and agricultural applications. They are commonly used for potable water storage, fire water storage, rainwater harvesting, and process water storage in manufacturing facilities. Their modular design allows for easy transportation, assembly, and customization to fit different space requirements.
We specialise in manufacturing and supplying storage solutions, including bladder tanks, sectional panel tanks, round steel tanks, and dam liners.
Our tanks are used in industries such as agriculture, mining, construction, firefighting, water treatment, and fuel storage.
The lifespan is dependent on the type of tank, kindly see below:
Yes, we provide accessories such as ladders, level indicators, vents, inlet, outlet, drain, and overflow fittings.
Yes, we provide full installation services, including site preparation and assembly.
Yes, round steel tanks are resistant to corrosion as they are either galvanised or made from aluzinc steel, both of which offer excellent protection against rust and weathering.
We can supply Round tanks PI up to 4million litres, square tanks up to 5million litres and bladder tanks up to 250000 litres
Aluzinc has a longer life span, superior corrosion protection properties but cost more.
Depending on your insurance providers requirements, our bladders comply with the requirements of the French Standard NFS 62-250 and are endorsed by the EU Fire Safety Services. However, most insurance companies require you to utilize robust material which includes Hot dipped galvanized steel or Aluzinc steel as an outer shell.
When building a tank the sheets are thicker at the bottom, the sheets get thinner and thinner as you go up row by row, the higher you go the more pressure is received at the bottom resulting in thicker sheets required at the bottom to withstand the pressure, this with the added working at heights which is generally harder and takes longer adds to the amount of days to install the tank, the additional material and labour required is what drives up the total price of the tank.
For our Sectional steel tanks, we have a tolerance of 5 mm, which means each plinth needs to be almost the same height. For the round tanks we have the same tolerance, the higher the tank the stricter we are when inspecting. This is mainly because a 10 mm deviation at the bottom is much more at the top.
Yes we do export our products and even provide installation services, we can also provide a site supervisor to supervise your own work force, this is generally more budget friendly, provides training for your team on our tanks but does usually result in a longer installation lead time.
To some extend yes, however, we follow SABS standards for our sectional steel tanks which is the standard most suppliers should follow when manufacturing, installing, and commissioning a sectional steel tank. The main difference comes in the type of sealants we use to “waterproof” our tanks, the internal bracings where some use a wall to floor configuration, wall to wall and some a hybrid of the two. We use a wall to floor configuration. Also, the holes spacing and sizing, for instance one might use bigger bolt holes but fewer holes while others might use smaller bolt holes with more holes.
Depended on our workload, we can manufacture Half a million litres of capacity in just 2 weeks for our bladders and for our round and square tanks you can work on 3 to 5 weeks.
No, we tailor make our bladders to the needs of our customers. We do have standard designs that limits wastage optimising our material and saving you money.
Typically, we require a 60% deposit and a signed copy of our T&Cs to commence with manufacturing. A 30% progress payment is due upon completion of installation and a 10% commissioning fee is payable upon wet testing of the tank(s).
Yes, these tanks can be installed on a sloped site as long as the dwarf wall foundation is levelled to within the accepted tolerance (5mm).
A bladder tank is a collapsible water storage tank. It unfolds as it fills up and it allows no air inside the bladder tank, this and the absence of sunlight prevents algae growth inside the tank.
Bladder tanks are typically used for temporary or short-term storage setups. While they can be used for long term storage they take up a large footprint of space compared to the capacity they stored, which makes the Pi tanks and sectional steel tanks more efficient.
