Water Tanks with a capacity greater than 400,000 litres are erected on a concrete slab or a ring beam base. Drawings, specs and details for the base are available upon request.
Best approach to bulk water storage:
Site Preparation: Ensure the concrete slab is fully cured, level, and clear of debris.
Top Ring & Roof Assembly: Assemble the first (top) ring of the tank directly on the slab. This is the stage where you fit the roof structure and the internal liner, as it is easiest to access before the tank is raised.
Jacking Setup: Attach heavy-duty jacks at equal intervals around the perimeter of the top ring.
The First Lift: Use the jacks to lift the top ring and roof assembly high enough to provide clearance for the next set of wall panels.
Adding Rings: Slide the panels for rings 2, 3, and 4 underneath the elevated section. Bolt them into place to extend the tank walls downward.
Progressive Lifting: Continue the jacking and fitting process until the desired height (number of rings) is reached.
Base Ring & Anchoring: Fit the final base ring. Once secured, the jacks are removed, and the tank is lowered to its final resting position on the slab.
Final Fittings: Install external accessories, including ladders, inlet/outlet piping, and overflow valves, to complete the assembly.
Safety Note: Ensure all jacks are synchronized during the lift to prevent the structure from tilting or buckling.
