- Balcony waterproofing. Tiled balconies leaking into the unit or parking bay below.
- Commercial waterproofing. Office roofs, podium decks and plant areas on larger buildings.
- Basement waterproofing. Parkades and basements with seepage through walls, slabs and joints.
- Joint sealing. Failed expansion joints on podiums, parking decks and facades.
- Shower waterproofing. Showers in apartments leaking into the unit below.
- Flat roof waterproofing. Concrete roofs on townhouses and low-rise blocks with ponding at outlets.
Apartment Blocks and Body Corporates
- Who approves. Roofs, podiums and facades are usually common property, so trustees or the managing agent approve the work.
- Who pays. A leaking balcony or shower inside a unit is often the owner's cost; check the scheme rules.
- Access. High-rise work needs rope access, a hoist or scaffolding, booked with building management.
- Residents. Noise, odour from primers and closed areas should be planned and communicated early.
Storm Season in Sandton
Summer thunderstorms dump a lot of water in a short time, and hail can damage roof membranes and skylights. Outlets on podiums and roofs need to cope with that volume. Plan big jobs for the dry winter months.

Get Waterproofing QuotesWhat Affects the Quote
- Height and access. Rope access, hoists and scaffolding are often a large part of a high-rise quote.
- Tiles on or off. Lifting and replacing tiles costs more than sealing over them, but often lasts longer.
- Working hours. Work limited to set hours in occupied buildings takes longer.
- Scope. One unit costs more per m² than a whole roof or podium done at once.
- Specification. Some buildings need a specific system or a consultant's spec, which narrows the options.
Finding the Source in Multi-Storey Buildings
- Trace it upward. Water in a ceiling may come from a balcony, shower, plumbing or roof one or more floors up.
- Test first. Ask for a flood or leak test before any tiles are lifted.
- Rule out plumbing. A plumber may need to pressure-test pipes so the wrong trade is not paid.
Questions to Ask a Sandton Contractor
- Have you worked on occupied apartment or office buildings?
- How will you reach the area, and who books the access?
- Which product system and membrane thickness will you use?
- What safety file and insurance can you provide to building management?
- What guarantee is offered in writing, and who holds it: the owner or the body corporate?
Waterproofing Sandton FAQs
My ceiling leaks but I live under another unit. Who fixes it?
Usually the owner of the unit where the water comes from, or the body corporate if it is common property. A leak test shows which.
Can a balcony be sealed without lifting the tiles?
Sometimes. A clear sealer can stop water through grout on sound tiles, but it will not fix a failed membrane underneath.
Can parkade leaks be fixed from inside?
Often yes, with crack injection, joint sealing or negative-side coatings, when the outside cannot be reached.
Do contractors need the building's approval first?
Yes. Most managing agents need a quote, safety file and insurance before work starts.
How much does balcony waterproofing cost in Sandton?
Ballpark R250 to R550 per m² with tiles off, before new tiles. Access and the number of units affect the price.
