Tank Liners

We have been dealing with Westarp for some time now. They have proven to be a valued supplier of choice for our roll tarps and trailer canvas guards on our grain trailer range. Some of the reasons we chose Westarp includes their value for money and great customer service. Plus when we have undergone a short notice repair job we have been able to rely on Westarp to provide the occasional quick turnaround job so we could keep our customers moving.

Tank Liners

Westarp’s tank liners are all manufactured at our factory in Western Australia, using only the best quality materials along with the latest welding machinery. Our qualified liner fabricators use the latest welding techniques and state-of-the-art machinery to produce liners of the highest quality.

Our liners can be manufactured using materials suitable for most liquids, from potable water to specialised chemicals. All the Liners are manufactured using the latest welding machines; these welders not only produce an watertight seam, but the dual head allows it to weld a secondary sealing tape over the main seam to prevent wicking in the material and maintain the integrity of the main seam.

The machines have built-in technology for measuring seam integrity. This continuously and consistently monitors weld temperature and seam welds with infrared thermal imaging cameras, and have alarms to pick up any failed seam.

Trial welds are performed before the start of a welding session. Samples of the weld are tested both for peel and shear strength, to verify the welding machine is producing welds that meet project specifications.

Vacuum Box Testers are also used to non-destructively test the integrity of welds and intersections. This is one of the safest and reliable non-destructive test methods available in the industry.

During the manufacturing phase, all work carried out in the factory is subjected to a rigorous and methodical QA (Quality Assurance) testing program with systems certified to ISO 9001.

Is your tank leaking? Concrete tank you’ve patched over and over but just won’t stop? It could be leaking from age, ground movement, damage or a combination of things! If it’s a metal tank, it may be rusting through. A Westarp Liner can stop the leak, as long as the tank is still structurally sound. If the tank can still take the weight and pressure, one of our industry leading liners can stop the leak. A Westarp Liner can be quickly and simply installed in most tanks and will ensure many years of extra life, or prolong the life of a new tank.

Please note: Poly tanks with a split are not able to safely withstand the weight and head pressure of being filled with liquid and are deemed not structurally sound, so will require repairing before a liner can be installed.
