As an example, our strata complex is 35 years old and has 35 units. One of the units has a tiled terrace that is about 40sqm. Around two years ago, water appeared to be leaking into the ceiling of the unit underneath. We asked our consulting engineering firm for a brief on how best to deal with the apparent leak. The cost came in at a projected $120K to lift all the tiles, replace the waterproofing and re-tile (new tiles) and by the way, replace the balustrade because it was 10cm short of current standards. For a leak? The explanation was that the job could only be done under the supervision of an engineer because it involved waterproofing, and the balustrade came into the picture because the tiles came up to the lower edge of the balustrade which brought it into the scope of works. Needless to say, we didn’t go ahead with that job. Rather, we had the whole terrace re-grouted at a cost of $19K. So far, no further leakage has been reported. Something is seriously wrong here.
