Concrete Tank Leak Test
Concrete Tank Leak Test
(OP)
I have a concrete tank that needs a leak test done. The leak test will be done after its already been backfilled and the tank is 21m by 21m and holds about 3000m3 of water. Wall thickness ranges from 600mm at the bottom to 450mm at the top (7.1m tall).
My question is once the tank is filled up, the concrete will absorb some of the water. How long should I wait before I start my actual measurement of change in water height. How long should I give the concrete to absorb the bulk of what it will absorb?

If you have time, you might want to wait a week as sometimes some small leaks seal themselves as the concrete re-hydrates from the liquid in the tank.

Soil backfill prior to leak testing was a mistake.
