Why water tank waterproofing differs in Aldarb

Aldarb is about 18.7 km from the sea coast (OpenStreetMap). The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data).

Before any coating is quoted for a water tank at a rest house or farm in Aldarb, the technician first checks the site's elevation and distance from the coast, because these shape how the tank is exposed to the weather. The centre of Aldarb sits about 79 m above sea level, and the town is about 18.7 km from the sea coast, so the work starts with an inland, elevated setting rather than a coastal one. Tanks in this kind of location are usually judged first on their interior condition and on how they sit on their base and walls, since those are the areas where moisture is most likely to enter and stay.

The rest of the assessment is left to the site visit, because it depends on what is actually in front of the technician. Surfaces are inspected for cracks, flaking, and old coatings, and the tank's shape and access are noted. The technician also decides whether the job calls for an internal tank coating, crack injection, or a membrane on the roof or base, since each has its own scope. Where a quote is needed, typical ranges can be given per square metre or per metre of crack, such as tank internal coating at SAR 25–60 per m², crack injection at SAR 40–120 per m, and epoxy coating at SAR 35–90 per m², but the final figure is set only after the measurements are taken on site.

To help the technician prepare, it is useful to have the tank's approximate dimensions, its material, and the date of any previous repair if known. Information on whether the tank holds potable water, and whether it is open or closed at the top, also helps in choosing the right system. Access to the tank and to the roof should be confirmed in advance, along with any restrictions on water supply during the work. Clear notes on known leaks or damp patches, with photos where possible, allow the visit to focus on the real problem and keep the job on schedule.

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

Signs worth paying attention to

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

Where the problem usually comes from

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

Tools we use in Aldarb

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.
