Rainwater Storage Bladder Tanks

Bladder Tanks


Bladder tanks are the ideal solution to those who have limited storage space or limited access. They are the lightweight alternative that can be rolled up to a fraction of their full capacity, allowing you to maximise the amount of water they can carry in a smaller area. Our bladder tanks are available with a frame and without a frame. With a frame, the tank can store up to 20% more water per square metre, the frame makes sure that the size always remains the same, and it ensures the tank always stays inside the frame and not touching any part of the building structure. Without a frame, reinforced material doesn't stretch, the footprint of the tank changes as it expands and contracts, and there is a risk that the tank might move in heavy rainfall or if the ground isn't level.
