Water tank waterproofing for warehouses in Allith

Why water tank waterproofing differs in Allith

Main roads in or near Allith: Al Laith Road, Amr Bin Al Aas Street. Allith is about 1.2 km from the sea coast (OpenStreetMap).

The centre of Allith sits about 5 m above sea level (SRTM open elevation data).

Allith sits about 5 m above sea level at its centre, and the coast is roughly 1.2 km away. For a water tank serving a warehouse, these two facts shape what the technician looks at first. Because the site is low-lying and close to the sea, salt-laden air and a shallow groundwater table are worth checking before any coating is chosen. The first inspection therefore focuses on whether the tank's base and lower walls show signs of moisture, salt crust, or the lifting of old coatings, since these are the areas most exposed to damp conditions.

Several items are left to the site visit, because they cannot be judged from a distance. The technician needs to measure the tank's internal dimensions, confirm the condition of the existing surface, and find any cracks, which are often the real source of leaks. Crack lines are measured in metres, so their total length determines the work involved. The access route, the tank's height, and whether the tank can be emptied for the job are also assessed on site, as they change how the work is organised. The choice of coating, whether tank internal coating, epoxy, or another system, depends on what the inspection shows.

The following information helps the technician prepare. Tank internal coating is priced from SAR 25 to SAR 60 per m², and crack injection from SAR 40 to SAR 120 per metre, so a clear measurement of both the wall area and the crack length gives a realistic basis for the quote. Epoxy coating ranges from SAR 35 to SAR 90 per m², while liquid roof waterproofing, where the warehouse roof drains into the tank area, runs from SAR 8 to SAR 25 per m². Noting which surfaces are involved, along with photographs and any previous repair records, allows the technician to match the system to the actual conditions rather than working from assumptions.

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

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

Causes we see in the field

• Construction joints.
• Cracks in the walls or floor.
• A common cause: damaged old coating.

How we choose the tool in Allith

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.
