This job started with a leak detection day where we found 1 major leak. Most of the grout had been corroded away due to prolonged acidic water and a lot of tiles were loose. We found water was also being lost through the waterproof barriers and through pipework that hadn’t been properly isolated.
We cut out the remaining grout, fixed back on the loose tiles. Cut out the major leak and repaired. The whole pool was then re-grouted.
