Get Waterproofing QuotesWhat Affects the Quote
- Size and condition. Spalled concrete and corroded steel need repair first.

Questions to Ask
- Approval. Is the coating approved for drinking water?
- Safety. Do your staff have confined-space training and equipment?

- Guarantee. What written guarantee applies, and what voids it?
Reservoir Waterproofing FAQs
Do reservoirs need to be drained to waterproof them?
For internal coatings, yes. Some crack injection can be done from outside while full.
Are reservoir coatings safe for drinking water?
Only products approved for potable water, cured as specified. Ask for the certification.
How often should reservoirs be inspected?
Regularly, and whenever leaks or water quality problems appear. Ask the contractor for a schedule based on the structure.
Can a steel tank be coated instead of replaced?
Often, if the steel is still sound after rust treatment. Badly corroded panels need replacing.
