What is specific about Baqiq for water tank waterproofing

Main roads in or near Baqiq: King Fahd Road. The centre of Baqiq sits about 83 m above sea level (SRTM open elevation data).

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..

Water tanks at rest houses and farms in Baqiq often sit in the open and take the full force of heat and sun, so the most common problem is cracking and seepage at the joints and walls of the tank. As the concrete expands and contracts through the day, hairline cracks open, and water slowly leaks out or cracks let in contaminants. Owners often notice damp patches on the outside or a drop in water level long before the tank looks visibly damaged.

Local conditions shape how we approach the job. The centre of Baqiq sits about 83 m above sea level, so the site is well inland and the tanks there are typically exposed to strong sun with little shade. That means the coating must handle heat cycling as well as water pressure. For tank interiors, a tank internal coating is priced at SAR 25–60 per m², while crack injection for visible leaks is priced at SAR 40–120 per m. Where the tank roof or top slab is exposed, liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² can shield it from the sun. Where insulation is needed to reduce heat gain through the tank walls, XPS boards at SAR 12–30 per m² are an option. The right mix depends on what the tank is made of and where the damage shows.

Before the visit, ask a few clear questions so the survey is useful. Tell the team the tank's size, its material, and whether the leak is inside or outside, and note any recent repairs. Ask for the exact area to be measured, since most coating work is priced per square metre. Confirm whether the tank is in use and how it will be emptied and refilled during the work. Finally, ask for a written breakdown of the proposed treatment, so you can compare the scope and the rates against the ranges above before agreeing to anything.

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

Signs worth paying attention to

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

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

Where the problem usually comes from

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

Tools we use in Baqiq

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.
