What is specific about Tabuk for water tank waterproofing

Team note on Tabuk: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Tabuk sits about 762 m above sea level (SRTM open elevation data).

Picture a family who owns a flat on the upper floors of an apartment block in Tabuk. Their building has a rooftop water tank that feeds the kitchen and bathrooms, and over the past year they have noticed damp patches on a bedroom ceiling and a faint smell of stale water in the corridor. They are not sure whether the leak comes from the roof, the tank, or the pipes, and they want to fix it without paying for work they do not need.

The local facts matter here. The centre of Tabuk sits about 762 m above sea level, which means the city is at a higher elevation than many coastal areas of the kingdom. Higher ground often brings a drier, more exposed climate for roofs and tanks, with strong sun heating the surfaces during the day and sharp temperature changes between day and night. That pattern stresses coatings and encourages small cracks to open up over time, so a tank or roof that looked sound a few years ago may now need attention. Owners should expect that water-holding structures in this city are worth inspecting regularly rather than only after a leak appears.

A sensible sequence starts with inspection. Check the roof surface and the tank walls for cracks, peeling coating and staining, and trace where the damp appears inside the flat. Next, decide on the repair scope. A crack in a wall may need crack injection, which is priced per metre at SAR 40–115 per m, while a worn roof surface may suit liquid roof waterproofing at SAR 10–25 per m² or a bitumen membrane at SAR 15–35 per m². If the tank itself is failing, the internal lining can be treated with a tank internal coating at SAR 25–55 per m² or an epoxy coating at SAR 35–85 per m². Finally, ask for written per-square-metre quotes for each item, confirm the area measured, and plan the work so the tank is drained and cleaned before any coating goes on.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
