Water tank waterproofing in Baqiq: the local context

Team note on Baqiq: 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 Baqiq: King Fahd Road.

The centre of Baqiq sits about 83 m above sea level (SRTM open elevation data).

Consider a homeowner in Baqiq who has a rooftop water tank serving a villa or apartment building. Like many owners in the area, they rarely think about the tank until water stains appear on a ceiling or the tank level drops faster than expected. By then, a small leak at the tank base or a cracked joint may have been slowly seeping for months. A preventive periodic check is far simpler and cheaper than repairing damage that has already reached the structure below.

The location matters. The centre of Baqiq sits about 83 m above sea level, which is a reminder that rooftop tanks here are exposed to direct sun, strong daily temperature swings and dust carried by wind. Those conditions stress coatings and sealants over time, so the protective layers on a tank and its roof can weaken even when nothing looks wrong from below. For the owner, this means the tank and its surrounding roof area should be treated as parts that age and need regular attention, not as fixtures that last forever untouched.

A practical routine starts with an inspection of the tank's inner and outer surfaces, the lid, the inlet and outlet fittings and the seams where walls meet the base. Next, check the roof area around the tank for cracks, ponding water and any lifting of existing membranes. If cracks are found, crack injection is priced at SAR 40–120 per metre, and liquid roof waterproofing at SAR 8–25 per m² is often suitable for open roof areas. Where the inside of the tank shows wear, tank internal coating at SAR 25–60 per m² restores the protective layer. Record each finding with dates, so the next check can confirm whether a problem is growing. Repeat the check on a regular schedule and after any unusual event such as heavy rain or a change in water taste or colour.

Preventive checks follow a written schedule instead of waiting for a fault.

When do you need water tank waterproofing?

The following signs are worth checking before they grow:

• 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

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

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.
