26 years of finding the real cause behind every waterproofing problem.
Most waterproofing problems are not where the stain appears. Water travels along laps, through cracked flashings, behind parapet copings and under failed coatings before it shows up on a ceiling tile. Sicon Group spends the time to trace the actual source before lifting a brush.
We work on commercial, industrial and retail buildings only across Pretoria, Johannesburg and the rest of Gauteng. Every job comes with a free site inspection, a written diagnostic report, a fixed quote and a written guarantee on the fix.
If your building has any of these, you have a waterproofing problem.
Common waterproofing problems Sicon Group diagnoses and repairs every week on commercial, industrial and retail buildings across Gauteng.
Damp ceilings & walls
Yellow staining, peeling paint or visible damp. Almost always a roof or parapet leak above, not condensation. We trace it back to the source.
Ponding water on flat roofs
Water that sits longer than 48 hours after rain. Kills bitumen, breaks down acrylics and overloads the slab. Needs a re-fall or a new system.
Blistered or peeling coatings
Bubbles, flaking or chalking means the old system has failed. Usually moisture trapped underneath or a primer that never bonded properly.
Cracked membranes
Torch-on bitumen splits at laps, acrylic spider-cracks across the slab, polyurethane lifts at upstands. Each one needs a different repair.
Leaking parapets & copings
Water tracking down internal walls from the parapet. Cracked coping joints, failed flashings and porous brickwork are the usual suspects.
Failed flashings & joints
Where the roof meets walls, pipes, vents or skylights. The weakest point in any waterproofing system, and the first to fail without proper detailing.
Recurring leaks after repairs
Same spot, year after year. Almost always means the original repair treated the symptom, not the cause. We re-diagnose and fix it properly.
Mould & staining
Black mould on ceilings, mildew on walls and damaged plasterwork. Symptom of chronic leak ingress that hasn't been fully cured yet.

Waterproofing problem questions, answered straight.
The leak only appears in one spot, is the rest of the roof fine?
Not necessarily. Water often enters one place and exits another. We inspect the full roof so the quote covers the real problem, not just the visible symptom.
Can you fix a waterproofing problem during the rainy season?
Yes. We work around weather windows for application and use systems suited to the conditions. For active leaks we can fit emergency temporary cover same-day.
Do you only do commercial buildings?
Yes. Sicon Group works on commercial, industrial and retail buildings only. We do not take on residential waterproofing.
What does the inspection cost?
The first site inspection, diagnostic and quote is free. You only pay once you approve the written scope and price.
What guarantee do I get?
Every waterproofing fix includes a written guarantee. The term depends on the system used and is stated up front in the quote.
Can you work while the building is operational?
Yes. Most of our retail and warehouse work happens around live operations. We plan around trading hours, tenants and safety files.
