Top Signs Your Durban CBD Building Needs Joint Sealing
Durban’s CBD is full of high‑rise buildings exposed to constant vibration, humidity and temperature changes. Over time, joints between concrete panels and facades deteriorate, allowing water to penetrate and damage the structure. Here are the top signs your building needs joint sealing immediately.
1. Visible Cracks and Gaps
Cracks between concrete panels or around windows indicate joint failure. These gaps allow water and air infiltration, leading to corrosion and damp.
2. Water Leaks and Stains
Brown stains or damp patches on walls and ceilings are early signs of water ingress through failed joints.
3. Mould and Odour Build‑Up
Persistent musty smells and mould growth near joints or corners show moisture penetration.
4. Noise and Vibration Cracks
Durban’s CBD traffic and building vibration cause joint movement. If cracks appear after heavy rain or construction nearby, sealing is overdue.
5. Age of Existing Sealant
Sealants typically last 5–10 years. If your building hasn’t been resealed recently, it’s time for inspection and renewal.
