Before we start: what we know about Samtah

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

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

Does a water tank for a hotel or serviced apartment building in Samtah really need waterproofing, given that the town is a long way inland? Yes, and the reason has more to do with the tank itself than with the weather. Samtah sits about 61 m above sea level, and the centre of town is about 22.6 km from the sea coast. Altitude and distance from the coast do not stop a concrete tank from leaking. Cracks, joints and aging linings allow water through wherever the tank is, so a property owner should treat tank waterproofing as routine maintenance rather than a response to a particular climate.

Our inspection starts with a walk around the outside of the tank and the roof area beneath it, looking for staining, damp patches and visible cracks. Inside, the tank is checked for surface breakdown, loose rendering and any places where the existing lining has lifted or peeled. Where cracks are found, their length is measured so that the cost of crack injection can be estimated, since that work is priced per metre at SAR 40–120 per m. Each surface is then matched to a suitable treatment, whether that is tank internal coating at SAR 25–60 per m², epoxy coating at SAR 35–90 per m², or another option from the price list. The inspector notes the area of each surface so the owner receives a clear breakdown before any work begins.

Before the visit, it helps to have a few things ready. Gather any previous waterproofing records, repair invoices or drawings of the tank and roof so the inspector can see what has already been done. Make sure the tank can be emptied or drawn down to a safe level on the day of the visit, and arrange access to the roof and the tank room. Note any leaks you have already noticed, including the location and when they appeared, because this information shortens the inspection. If the building has more than one tank, list each one, since each tank is inspected and priced on its own surfaces.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

Signs worth paying attention to

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

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

Where the problem usually comes from

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

Tools and methods, and when we use them

How the work is done, step by step

1. Emptying and ventilation: The tank is emptied and ventilated before entry.
2. Cleaning and preparation: Loose material is removed down to a sound surface.
3. Crack treatment: Active cracks are treated first.
4. Coating layers: A material intended for drinking-water tanks is applied.
5. Disinfection and fill test: The tank is disinfected and the level is monitored after filling.
