Picture a family who bought a duplex in Aldawadmi, with the upper unit rented out and a balcony that catches the afternoon sun. After a few rainy weeks they notice damp patches on the ceiling below the balcony, a hairline crack along the slab edge, and a faint smell in the lower bathroom. They are not sure whether the problem is the roof, the balcony floor or the bathroom above, and they want a fix that lasts without paying for work they do not need.
The town sits about 976 m above sea level, which means it is high ground with a noticeable temperature swing between day and night. Those daily changes make concrete expand and contract, so small cracks open and close over time and let water through, especially at the joints between the floor and the balcony edge. For a duplex, water that enters one unit damages the other, so the owner has a shared interest in acting early. Budgeting also helps: crack injection is priced per metre, typically SAR 40–120 per m, while liquid roof waterproofing runs SAR 8–25 per m², so a targeted repair costs far less than covering everything.
A sensible order starts with inspection. Walk the balcony after rain, mark every crack, and check the bathroom floor and the water tank for staining. Next, treat the cracks, using crack injection where the gap is narrow and running water is the issue. Then choose the surface system: bitumen membrane at SAR 15–35 per m² or spray foam at SAR 20–45 per m² suit balconies and roofs, while epoxy coating at SAR 35–90 per m² suits surfaces that take heavy foot traffic. Finish with the bathroom, where bathroom waterproofing costs SAR 15–40 per m², and check the tank interior if it has not been recoated. Keep notes and photos at each step so future work is easier to plan.
In a duplex, the two floors often share lines, so tests are done floor by floor.
