Water tank waterproofing in Buraydah: without breaking

Before we start: what we know about Buraydah

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).

Before any coating goes on a water tank in Buraydah, the first check is the tank's location and its exposure. The centre of Buraydah sits about 606 m above sea level (SRTM open elevation data), which means the city is on a high plateau rather than the coast. In practice this affects how the tank is filled, how the water pressure behaves and how quickly the sun heats the top surfaces, so the technician looks first at the roof, the access points and the way the tank is exposed to daytime heat. A tank that sits in full sun will see more expansion and contraction in its lining, so the surface is inspected for old cracks, blistering and any place where the existing coating has lifted.

Several things are left to the site visit, because they cannot be judged from a description. The technician needs to see whether the tank is steel, concrete or polyethylene, whether it has an internal lining already, and how much water is inside when the work starts. The condition of the crack and its depth can only be confirmed by hand. The price range for each option depends on the surface area measured on site, so the final cost follows the measurement and the chosen method. Common options include tank internal coating at SAR 25–55 per m², epoxy coating at SAR 35–85 per m² and crack injection at SAR 40–115 per metre, while a roof with liquid waterproofing is priced at SAR 10–25 per m². Each of these ranges is a starting guide only, and the actual figure is set after the visit.

To help the technician, it is useful to have a few details ready before the visit. Note the approximate age of the tank, any past leaks, and whether the water tastes or smells changed, as these point to where to look first. Give access details, including whether the tank is on a roof, in a basement or in a courtyard, and whether the water supply can be shut off during the work. Mention whether the tank is used for drinking water, since that will decide which coating products are suitable. Having these facts written down saves time on the day and makes the on-site assessment more accurate.

The aim is to locate the cause with instruments first, so any opening is limited to one point.

Signs that call for water tank waterproofing

The following signs are worth checking before they grow:

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

The most common causes

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

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.
