Water tank waterproofing in Buraydah: the local context

Team note on Buraydah: 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 Buraydah sits about 606 m above sea level (SRTM open elevation data).

Is it worth coating a water tank on a rest house or farm in Buraydah, or should I just replace it when it leaks? For most owners the answer starts with the ground under the tank. The centre of Buraydah sits about 606 m above sea level, and a tank that loses water through its walls or floor can quietly drain a farm's supply before anyone sees a wet patch. Tank internal coating is priced at SAR 25–55 per m², which is usually far less than a full replacement and keeps the existing structure in service. Crack injection, priced at SAR 40–115 per metre, is often the right fix when the leak traces back to one or two hairline cracks rather than the whole surface.

The inspection starts with a drained or near-empty tank so the technician can see the walls, floor, and joints clearly. The inspector looks for cracks, flaking old coatings, damp patches on the outside, and signs of water staining along seams. Each defect is measured so the surface area and the length of any crack can be priced separately, since internal coating is charged per m² while crack injection is charged per metre. The inspector also checks whether the tank cover and any roof-level surfaces above it are holding water, because a leaking roof can look like a leaking tank. Based on what is found, the visit ends with a recommendation for which method suits the damage, whether that is a coating, an injection, or a combination of both.

Before the visit, empty the tank as much as you safely can and leave access clear around the outside walls and the roof hatch. Note when you first noticed low water levels or damp ground, and mark any cracks or staining you have already seen. If the tank serves a rest house with guests, plan the visit for a period when the supply can be paused, since the interior work needs the tank dry and sealed for the curing time. Having the tank's dimensions and the age of any previous coating to hand will help the inspector give you a clear and accurate estimate.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

When do you need water tank waterproofing?

If you notice one of these signs in Buraydah, it is a good moment to talk to the team:

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

The most common causes

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

Tools and methods, and when we use them

The steps in order

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.
