Why water tank waterproofing differs in Sabya

Sabya is about 16.7 km from the sea coast (OpenStreetMap). The centre of Sabya sits about 40 m above sea level (SRTM open elevation data).

Main roads in or near Sabya: King Fahd Road, King Abdulaziz Road, King Abdullah bin Abdulaziz Road. Team note on Sabya: 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 tank waterproofing in Sabya starts with the location itself. The centre of Sabya sits about 40 m above sea level (SRTM open elevation data), and it is about 16.7 km from the sea coast (OpenStreetMap). Because the town is inland and elevated rather than close to the shoreline, the first check is the tank's position on the roof or ground, the condition of the concrete or steel shell, and whether any existing coating has already lifted, cracked or chalked. Tank internal coating is typically priced at SAR 25–60 per m², so the surface area being treated will set the scope before any material is chosen.

What cannot be settled from a description alone is left for the site visit. The technician needs to see the tank walls, the floor, the inlet and outlet pipework and any joints where cracks have appeared. Crack injection, priced at SAR 40–120 per metre, can only be scoped once the length and direction of each crack are measured on site. Liquid roof waterproofing at SAR 8–25 per m² or bitumen membrane at SAR 15–35 per m² are alternatives for the tank cover, and the choice depends on how the roof drains and how much foot traffic it carries. The visit is also where the technician confirms whether the surface is dry enough to accept an epoxy coating, which is priced at SAR 35–90 per m², or whether spray foam at SAR 20–45 per m² is a better fit for irregular shapes.

To help the technician prepare, note the tank's dimensions, its age, any previous repairs, and whether the water stored is for drinking or for general use. Record where leaks have been noticed and how quickly the level drops. If the tank sits on or beside a basement, mention it, since basement waterproofing is priced at SAR 50–150 per m² and may need a separate assessment. Photographs of the cracks, the roof and the pipe connections, taken in daylight, make the first visit faster. Clear access to the tank and a dry surface on the day of the visit also help the work begin without delay.

Each job ends with a written report that carries a verification code you can check on our site.

Signs worth paying attention to

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

Causes we see in the field

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