Wall & Shower Waterproofing Services in Pinehurst
Looking for professional wall & shower waterproofing in Pinehurst? Waterproofing Durbanville is your local Northern Suburbs team for wall & shower waterproofing — free on-site inspection, written quote, 5-10 year workmanship guarantee.
Wall and shower waterproofing addresses the wet areas inside your home — leaking showers, bath surrounds, splashbacks and the external wall faces that ferry rain into a cavity. In Durbanville and the high-rise belts of Tygervalley, Plattekloof and Bellville, a single failed shower tray is the most common trigger of body-corporate damage claims, with the unit below catching the bill. Our listed contractors diagnose whether the failure is at the silicone, the grout, the substrate or the original tile bed, then strip back only what is necessary, apply a cementitious tanking slurry or liquid polyurethane membrane, flood-test for 24 hours, and re-tile. External walls get a clear penetrating sealer or a pigmented elastomeric coating depending on the brick type. Every job ships with photographic before/after evidence suitable for trustees, managing agents and short-term insurance assessors.
We serve Pinehurst with same-day quote response and free no-obligation roof inspections. We use approved-applicator systems from Index, Derbigum, Sika and Plascon. All work backed by our 5-10 year workmanship guarantee.

Why does my shower leak even though the silicone is fine?
Silicone is the last 2% of the waterproofing system, not the first 98%. If the cementitious membrane under the tiles was skipped, applied too thin, or never carried up the wall and across the floor-to-wall fillet, water tracks behind the tiles through the grout — which is porous by design — and exits through the back of the wall or through the slab below. The silicone bead at the visible joint is irrelevant once water is already behind the tile face. Diagnosis is a moisture-meter reading on the dry side of the wall: a wet outside wall with intact silicone is the textbook signature of a failed tanking layer.
Do tiles need to come off to fix a leaking shower?
Not always. If the substrate is sound and the leak is mild, a clear penetrating sealer plus epoxy regrout (R3,500-R7,500) buys 5-8 years and avoids the dust and disruption. If the substrate has hollow tiles, cracked grout lines wider than 2mm, visible damp on the outside wall, or the leak is dripping into the unit below, tiles must come off, the membrane must be reapplied properly, and the area is re-tiled (R8,000-R18,000). The free inspection includes a moisture-meter survey to determine which option fits.
How long does shower waterproofing last?
A correctly applied two-coat cementitious tanking slurry with proper corner reinforcement lasts 15-20 years before any review is needed. Liquid polyurethane systems last 10-15 years. The grout and silicone on the tile face age faster and should be redone every 5-7 years as routine maintenance — that maintenance is not the waterproofing failing, it's the surface finishes. All listed contractors offer a 10-year workmanship guarantee on full re-waterproofing.
Penetrating sealer vs full re-tile — which should I choose?
Penetrating sealer (silane/siloxane based) plus epoxy regrout is the right call when tiles are sound, grout is intact but porous, and the leak is slow. It is not a fix for a failed membrane — it is a fix for porous grout. Full re-tile with new tanking is the right call when there is visible damp on the outside wall, tiles sound hollow, the unit below has water marks on the ceiling, or the original installation predates 2005 (when SANS 10400-L tanking became standard practice). When in doubt the contractor will quote both options so you can weigh cost vs longevity.
What is a 'tanking slurry'?
A tanking slurry is a two-component cementitious waterproofing membrane applied as a paint-on coating before tiling. Two coats build a continuous, flexible, fully bonded waterproof skin across the shower floor, up the walls, and across every junction. Common SA brands are Sika SikaTop Seal-107, ABE Super Laycryl, Aquaflex and Cemix Aquablock. Reinforcing fabric is bedded into the first coat at every corner and pipe penetration. Once cured (typically 24-48 hours) and flood-tested, tiles are bonded directly over it. It is the South African standard for internal wet-area waterproofing under SANS 10400-L.
Can a leaking shower cause damp on the wall outside?
Yes — and it is the single most common cause of an isolated damp patch on an external bedroom or hallway wall that backs onto a bathroom. Water tracks horizontally through the wall cavity, often emerging 1-2 metres from the actual leak source, which is why home-owners frequently mistake it for rising damp or a roof leak. The diagnostic giveaway is the damp pattern matching the height of the shower head or the bath rim on the other side of the wall. In sectional-title blocks the same mechanism feeds into the unit directly below — a common trigger for body-corporate insurance claims, and one of the biggest categories of work our Durbanville contractors handle.
