What is specific about Dhahran for water tank waterproofing

Team note on Dhahran: 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 Dhahran sits about 16 m above sea level (SRTM open elevation data).

Dhahran is about 5.9 km from the sea coast (OpenStreetMap).

Water tank waterproofing for offices and commercial complexes in Dhahran begins with the setting. The centre of Dhahran sits about 16 m above sea level, and the city is about 5.9 km from the sea coast. Both facts shape what the technician looks at first. A tank on a site at this elevation is not rain-fed in the way a low, flood-prone lot would be, and the proximity to the coast means salt-laden air and humidity are part of the working environment, so the inspection starts by confirming the tank's exposure and how the coating will handle it.

What is left to the site visit is the condition of the tank itself. The technician must see the surfaces, the joints, the inlet and outlet points, and any cracks before a method is chosen. Tank internal coating is priced at SAR 25–60 per m², while crack injection runs at SAR 40–120 per metre, so the length and type of cracks change the job considerably. The visit also establishes the actual wetted area, whether the tank is roofed, and whether it sits partly below ground, since basement-style conditions bring different costs and approaches. Epoxy coating at SAR 35–90 per m² and spray foam at SAR 20–45 per m² are both candidates, and the choice depends on what is found on the day, not on the price list alone.

Information that helps the technician includes a clear record of the tank's dimensions, its age, any past repairs, and how the water is used, because potable and non-potable storage may call for different materials. Roof exposure should be noted separately, since liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m² are used for open roof areas, and XPS boards at SAR 12–30 per m² may suit insulated sections. Photographs of the tank walls, roof and any leaks, along with the building's access arrangements and working hours, allow the team to plan materials and timing. A complete picture at the start keeps the work accurate and avoids surprises once coating begins.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.

When do you need water tank waterproofing?

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

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

The most common causes

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