Sound familiar?
- The wall or ground next to our underground tank is always wet.
- The tank level drops overnight with no water being used.

- The old tank coating is peeling off in sheets.
- We have a new concrete tank that needs lining before use.
Every one of these has a lasting fix — once the source is found.
Send Photos on WhatsAppWhat we check before quoting water tank waterproofing
Most failed waterproofing jobs treated the stain, not the source. These are the points we check on every survey before we recommend a system or a price.
Concrete condition & cracks
Cracks, honeycombing and exposed or rusting rebar mapped inside the tank — they are repaired before any lining goes on.
Old coating adhesion
Peeling or blistered coatings are a contamination risk as well as a leak path, so failed layers are removed back to sound concrete.
Pipe entries & manhole
Inlet, outlet and overflow pipe sleeves and the manhole frame sealed — these joints leak long before the walls do.
Potable-water compliance
Only linings certified for drinking-water contact are used, and the tank is cured, flushed and cleaned before it is refilled.
