Balcony Waterproofing in Cape Town

Why balconies are prone to water penetration

Balconies are exposed to direct weather, movement, and foot traffic, all of which put stress on the waterproofing layer beneath the surface finish. Once that layer cracks or lifts at an edge or upstand, water finds its way through - often silently, until it shows up as a stain on the ceiling below.

Common signs of failed balcony waterproofing

Hairline cracks in the balcony surface, water pooling instead of draining away, tile or screed lifting at the edges, and damp or staining on the ceiling of the room underneath are the most common warning signs.

Waterproofing repairs vs. full waterproofing

A balcony with a small, localised failure may only need a targeted repair to the affected area. A balcony with widespread cracking, ponding, or an old system nearing the end of its life is usually better served by re-waterproofing the full surface. We assess the balcony to recommend which applies.

Maintenance considerations

Keeping drainage outlets clear and addressing small cracks early goes a long way toward preventing a balcony waterproofing failure from turning into a ceiling repair below it.
