Shower & bathroom waterproofing Randburg

Tiles and grout are not waterproof. Water soaks through grout lines and hairline cracks, and without a membrane underneath it reaches the wall, floor slab and the room next door. A proper tanking system behind the tiles is what actually keeps water in the shower.

Sometimes. If the leak is from failed grout or silicone, regrouting and resealing can solve it. If water is getting behind the tiles because there is no membrane, or the membrane has failed, the tiles must come off for a lasting fix. A specialist should test before recommending either.

Yes, as long as the new shower gets a full membrane, correct falls to the drain and a properly sealed waste. Bath-to-shower conversions often leak when tiles go straight onto old walls. Insist on waterproofing before tiling.

In Randburg, budget R2,500 to R6,000 to tank a shower stall before tiling, and R6,000 to R15,000 for a whole bathroom floor and shower. Removing existing tiles, repairing the screed and retiling add to that. A clear quote shows the waterproofing, tiling and rubble removal as separate lines.
