If your balcony tiles look tired, or worse, if you’ve spotted a damp patch on the ceiling below, it’s worth understanding what a proper balcony strip and re-tile actually involves before you commit to one. Many Centurion homeowners assume it’s simply a case of lifting old tiles and laying new ones. In reality, the tiles are the last thing that gets touched. Everything that matters happens underneath them, and it’s a process TT Waterproofing has been refining on balconies across Pretoria East since 2014.
Why the Tiles Aren’t the Real Problem
New tiles on a balcony with failed waterproofing underneath will look great for a while and then start leaking again. Balconies, especially cantilevered slabs that sit above living rooms, take constant exposure to sun, rain and temperature swings. Over years, the waterproofing membrane beneath the tiles breaks down, cracks appear, and water starts tracking through the slab into the ceiling below. By the time a stain or a soft patch of paint shows up, the damage has usually been developing for a while. Our team has seen this pattern repeatedly across cantilevered balconies in particular, which is why re-tiling over hidden failure is never our starting point. It doesn’t solve anything.
Step 1: Stripping the Surface
The process starts with removing the existing tiles and screed entirely, exposing the slab underneath so it can be assessed properly. This is often the point where a homeowner sees just how much moisture has been sitting under the old tiles, which is usually the source of the leak everyone’s been trying to track down.
Step 2: Inspecting and Repairing the Slab
With the surface cleared, our team inspects the slab thoroughly. Any cracks, weak spots or previous patch repairs are identified and dealt with before any waterproofing goes down. Skipping this step is one of the most common reasons balcony waterproofing fails again a year or two later, so we treat it as a non-negotiable part of the job rather than a formality.
Step 3: Applying the Waterproof Membrane
This is the part that actually stops the leak. We apply a waterproof membrane across the full slab, with particular attention paid to edges, drip grooves, thresholds and drainage outlets. These detail points are where balconies most commonly fail, so our team treats them with the same care as the main surface rather than as an afterthought, ensuring every junction is properly sealed before moving on.
Step 4: Screeding to the Correct Fall
A fresh screed is laid over the membrane, sloped correctly so water drains towards the outlets instead of pooling. Getting this fall right takes experience and a careful eye, since poor fall is a quiet cause of long-term balcony damage. Standing water puts constant pressure on the waterproofing layer beneath it, which is exactly the kind of slow-building problem our inspections are designed to prevent.
Step 5: Re-Tiling to a Neat Finish
Only once the waterproofing and screed are sound does re-tiling begin. At this stage, the focus shifts from function to finish, giving the balcony a clean, refreshed look that will actually last because of the work that happened underneath it.

Frequently Asked Questions
How do I know if my balcony needs a full strip and re-tile, or just a repair? If the waterproofing beneath the tiles has failed, a full strip is usually necessary. Surface-level tile damage without underlying leaks may only need a partial repair. Our on-site assessment is the best way to know which applies to your balcony.
How long does a balcony strip and re-tile take? It depends on the size of the balcony and the extent of any slab repairs needed. Once we’ve inspected the site in person, we’ll give you a clear itemised quote and timeline before any work begins.
Will re-tiling alone fix a leaking balcony? No. If the waterproofing membrane underneath has failed, new tiles on top will only mask the problem temporarily. The leak will return until the membrane itself is properly repaired or replaced.
