What is specific about Tabarjal for water tank waterproofing

Team note on Tabarjal: 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 Tabarjal sits about 548 m above sea level (SRTM open elevation data).

For warehouses in Tabarjal, the problem we see most often with water tanks is leakage at the base and along the internal walls, where years of moisture and sediment break down the surface. Because the water sits in a warehouse setting, small seepage can quietly spread to the floor and stored goods before anyone notices. Early signs include damp patches on the tank exterior, staining on the foundation, and a drop in water level that cannot be explained by use. Tank internal coating is typically priced at SAR 25–60 per m², and crack injection at SAR 40–120 per metre, so catching a fault early keeps the repair scope small.

Tabarjal sits about 548 m above sea level, and that elevation shapes how we approach the job. At this height, the surrounding ground and the tank itself are exposed to larger day-to-night temperature swings, which cause the surface to expand and contract and encourage hairline cracks. Our approach therefore starts with a careful inspection of joints and cracks before any coating is chosen. Where the tank base or any connected basement area is involved, basement waterproofing is priced at SAR 50–150 per m², and epoxy coating at SAR 35–90 per m², so the right material depends on what the inspection finds rather than a single standard product.

Before the visit, ask the provider to confirm which parts of the tank and structure they will assess, including the base, walls, and any connected roof or basement areas. Request a clear written breakdown using the local rate for each surface type, such as tank internal coating, crack injection, or liquid roof waterproofing at SAR 8–25 per m², so you can compare the scope against the price. Ask how they will manage stored goods and access during the work, and whether they will test the tank after repair before it returns to service. Finally, ask what the warranty covers and how long it lasts, and make sure everything agreed is in writing before work begins.

For warehouses, work is phased around operations and stored goods.

When do you need water tank waterproofing?

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

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

Causes we see in the field

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

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.
