Balcony waterproofing Bryanston

Sometimes. Clear penetrating sealers and over-tile membranes work when tiles are sound and the leak is through grout. If water is trapped under the tiles, falls are wrong or tiles are drummy, they must come up for a lasting fix. A specialist should test before recommending either.

Usually because there is no membrane under the tiles, or it has failed at the edges, the drain or the door threshold. Water soaks through grout, travels along the slab and appears on the ceiling below. Finding the entry point is the first job.

Yes. Many older Bryanston houses have upstairs balconies over living areas, often with no membrane at all. A full strip, membrane and retile solves the leak permanently, and it is a good time to update the balustrade.

Often. Posts bolted through the tiles into the slab create holes in the waterproofing, and if they are not sealed properly, water runs straight down. Side-fixed or properly sealed base plates reduce the risk. Check them whenever a balcony leaks.

Budget R250 to R600 per m² for a surface sealing system on a Bryanston balcony, or R900 to R1,800 per m² if the tiles must come up for a proper under-tile membrane. Balustrade fixings, drains and edge details can add to it. Ask for a written guarantee.
