Balcony leaks can be a bit complex to diagnose and fix properly. The key to waterproofing a balcony is the membrane layer that sits over the structural substrate. This membrane is what stops any water that seeps through the grout lines or cracks in the tiles from getting through to the structure below. Instead, it collects the water and channels it safely over the balcony edge. If you’re seeing leaks underneath, it’s a strong indication that this waterproofing membrane has been compromised. The correct repair process involves removing all the existing pavers or tiles, applying a new waterproofing membrane, and then relaying new pavers or tiles over the top. In the meantime, you might be able to minimise the issue by trying to locate exactly where the water is penetrating. Go over the surface carefully and check for any visible cracks or gaps in the pavers or grout. If you can identify specific spots where water is seeping in, sealing them with a product like Sikaflex 11 FC can help as a temporary measure. However, it’s important to note that this kind of patch repair doesn’t fix the underlying problem. The water should never be able to reach the substrate in the first place. For a long-term solution, it’s best to have the area inspected by a qualified waterproofing specialist, who can assess the extent of the damage and recommend the proper way to reinstate the membrane. Please let me know if you have any questions. Mitchell
