Water tank leakage can waste water and damage surrounding walls or foundations. Before waterproofing, the tank should be emptied and inspected so cracks, weak joints and surface defects can be treated correctly.
Preparation matters
Remove loose material and contaminants, repair visible defects and allow the surface to reach the condition required by the selected system. Any coating used inside a drinking-water tank should be suitable for potable-water contact and fully cured according to its product instructions before the tank is refilled.
After the waterproofing work
- Follow the specified curing and cleaning procedure.
- Inspect the tank periodically for new cracks or damp patches.
- Keep covers, access hatches and plumbing connections in good condition.
