Water tank waterproofing in Dhahran: the local context

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).

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 most common problem with water tank waterproofing in clinics is a slow leak that appears at the joints, corners and wall-to-floor seams of the tank, where the lining has broken down under constant wet and dry cycles. Clinics depend on a steady supply for sterilisation, dental units, dialysis and handwashing, so a leak that seems minor can quickly affect daily operations and hygiene. Early signs include damp patches on adjoining walls, a drop in tank level without visible spillage, and cracks that reappear after a short time.

Local conditions in Dhahran shape how this work should be approached. The centre of the city sits about 16 m above sea level, and it is about 5.9 km from the sea coast, which means the tanks are not in a low-lying flood zone but still sit in a hot, dry, coastal climate where salts and temperature swings stress coatings. Because the sea is close, the surface preparation step matters more: salt residue and moisture in the concrete must be managed before any internal coating is applied, or the new layer may lift. A clinic tank is therefore treated as a hygiene system first and a structure second, with the lining chosen for durability and for suitability with drinking water, not just for water-resistance alone.

Before the visit, ask a few clear questions so the assessment fits your clinic. Confirm the tank's capacity, its material (concrete or steel), whether it is above ground or below, and how long the building has been using it. Ask whether the tank is drained and cleaned during inspection, how the works will be scheduled around clinic hours, and what will be done about water supply during the job. Request a written breakdown that lists each item, such as internal tank coating, crack injection and any associated roof or basement work, with its rate per unit, so you can compare the scope against the figures quoted.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

Signs worth paying attention to

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

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

Causes we see in the field

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

Tools we use in Dhahran

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.
