Deck & Balcony Waterproofing in Bloemfontein
Concrete decks and balconies leak when their waterproofing membrane fails, and the water shows up in the room below weeks or months later. We assess the substrate, repair cracks and deterioration, then apply the appropriate pedestrian-grade waterproofing system for a deck that stays dry under foot traffic and weather.

Frequently Asked Questions
Can I tile over a waterproofed deck?
Yes. The waterproofing membrane is applied first, then a protection screed, then tiles. The tiles are not the waterproofing layer - the membrane underneath is.
My balcony has tiles already. Do they need to come off before waterproofing?
Usually yes. If tiles are present and the waterproofing has failed, the tiles need to come off to allow proper surface preparation and membrane application. Applying waterproofing over existing tiles rarely works long-term.
