Water tank waterproofing in Samtah: the local context

Team note on Samtah: 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.. Main roads in or near Samtah: Al-Turshiyah and Al-Najmiyah Road, Samtah.

The centre of Samtah sits about 61 m above sea level (SRTM open elevation data). Samtah is about 22.6 km from the sea coast (OpenStreetMap).

Restaurants in Samtah rely on storage tanks for kitchen and washing water, and the most common problem we see is seepage through hairline cracks and failed joints in the tank walls and base. Because a restaurant draws water through the working day, even a small leak can drain a tank faster than expected, and it often goes unnoticed until the pump runs constantly or damp patches appear on the surrounding floor. A tank coating that is applied without first sealing the cracks will simply trap moisture behind it, so the repair has to start with finding and treating the weak points before any protective layer goes on.

The local setting shapes that approach. The centre of Samtah sits about 61 m above sea level, and the town is about 22.6 km from the sea coast, so the work is planned around an inland site rather than one exposed to salt-laden air on the coast. A tank coating for this property type typically falls in the SAR 25–60 per m² range, while crack injection is priced separately at SAR 40–120 per metre, which makes a clear inspection of the tank walls and joints the first step. Where the tank sits in a basement or ground-level plant room, basement waterproofing at SAR 50–150 per m² may also be relevant to protect the surrounding structure, and this should be checked on the visit.

Before the visit, ask the provider to confirm which parts of the tank and building are included, such as the internal tank walls, the base, the roof of any tank, and any adjoining basement. Ask how cracks will be located and whether crack injection is quoted per metre, and request a clear breakdown of the per-square-metre rates for each area. Also ask how long the tank must stay empty during curing and whether the restaurant can plan around that downtime before work begins. Clear answers on these points make it easier to compare quotes fairly.

For restaurants, visits are planned outside service hours and recorded for the premises file.

Signs worth paying attention to

The following signs are worth checking before they grow:

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

Causes we see in the field

• A common cause: construction joints.
• Damaged old coating — we check this before anything else.
• Cracks in the walls or floor — we check this before anything else.
