Water tank waterproofing in Albaha: the local context

Team note on Albaha: 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 Albaha sits about 2178 m above sea level (SRTM open elevation data).

Water tanks on apartment roofs in Albaha are the part of the building that most often starts leaking, and the problem usually shows up as damp patches on the ceiling of the top floor or as stains running down internal walls. Tanks sit in direct sun for long hours, and the constant expansion and contraction of concrete and coatings opens hairline cracks at joints and corners. Water then seeps through, the coating beneath the surface lifts, and what looked like a small patch turns into a repair across the whole inner surface. For this property type, the work is less about a single leak and more about restoring the tank as a sealed container.

Albaha sits at about 2178 m above sea level, which shapes how we approach each job. At that altitude the air is cooler and drier than in the coastal cities, yet the sun is still strong, so surface temperatures on exposed roofs and tank lids can swing sharply between day and night. That daily movement is why we pay close attention to flexible coatings and to how well a product bonds to a surface that has already expanded and cracked. The cooler climate also means curing times and surface preparation need care, since moisture and temperature affect how a coating sets. Our approach here starts with an assessment of the existing lining, the cracks, and the roof above, rather than applying a standard treatment without looking first.

Before any visit, ask the provider what they plan to inspect and how they will price the job. Ask whether the quote is per square metre for the tank's internal coating, the roof area, or the crack injection, and whether it uses the ranges set for this work in the Kingdom. Ask how the tank will be emptied and refilled, and how long the water supply will be affected. Ask what surface preparation they include and whether repairs to cracks are covered before a new coating goes on. Finally, ask what the warranty covers and in writing, so you know exactly which parts of the tank and roof the work protects.

In apartment buildings, the floor below is often where a leak shows first.

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
• Deposits and flaking inside the tank
• A tank that leaks after testing

Causes we see in the field

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

Tools and methods, and when we use them

From the first visit to the report

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.
