Why water tank waterproofing differs in Ahad Almasarihah

Team note on Ahad Almasarihah: 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 Ahad Almasarihah sits about 667 m above sea level (SRTM open elevation data).

Picture a warehouse owner in Ahad Almasarihah who keeps stock on site and relies on a rooftop or ground-level water tank to keep operations running. Over time, the tank walls and joints can weaken, seepage starts near the base, and the owner notices damp patches on storage floors or staining on the inside walls. By the time the problem is obvious, water may already have reached the stored goods, so the owner wants a clear plan for protecting the tank before losses grow.

The local setting matters here. The centre of Ahad Almasarihah sits about 667 m above sea level, which means the area is a relatively elevated location. For a warehouse owner, this is a reminder that the site and its water systems should be checked as a whole, with attention to how water moves across roofs, drains and the tank base. Tank internal coating is priced at SAR 25–60 per m², while liquid roof waterproofing typically falls within SAR 8–25 per m², so it helps to inspect the roof and the tank together and budget for both areas in one plan.

Start by inspecting the tank interior and exterior for cracks, flaking coatings and wet patches, and mark each defect so the scope is clear. Next, deal with active cracks first using crack injection, which is priced at SAR 40–120 per metre, before any surface coating goes on. Then prepare the tank internal surface and apply tank internal coating across the full wetted area, measuring the total area so the quote matches the real work. Where the tank sits on the roof, treat the roof with liquid roof waterproofing or a bitumen membrane, which ranges from SAR 15–35 per m², to protect the structure beneath. Finally, record the completed work, schedule a follow-up inspection, and keep a simple log of any new seepage so the owner can act early next time.

For warehouses, work is phased around operations and stored goods.

Signs worth paying attention to

These are the signs most often linked to water tank waterproofing:

• Deposits and flaking inside the tank
• A tank that leaks after testing
• Unusual colour or taste in the water

Where the problem usually comes from

• Cracks in the walls or floor.
• Damaged old coating — we check this before anything else.
• Construction joints.
