Water tank waterproofing for clinics in Alnuayriyah

Before we start: what we know about Alnuayriyah

Team note on Alnuayriyah: 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 Alnuayriyah sits about 49 m above sea level (SRTM open elevation data).

The centre of Alnuayriyah sits about 49 m above sea level (SRTM open elevation data), which places the area on relatively level ground rather than the steep slopes found in some parts of the Eastern Province. For clinic owners, this means rooftop and ground-level water tanks are usually set in stable, even foundations, but the tanks still need protection from the moisture and heat that shape the local climate. A tank that sits on a flat site and is exposed to daily temperature swings will expand and contract, so the waterproofing must remain flexible enough to follow that movement.

Because the ground is comparatively level, drainage around the base of a tank can pool if the surrounding surface is not sloped away from the structure. Our technicians therefore check the coating and the surrounding area together, so that the finish inside the tank and the sealing outside it work as one system. Tank internal coating is priced at SAR 25–60 per m², and clinics that choose this option gain a smooth, sealed surface that resists the build-up of sediment and keeps the stored water clean for patient use, sterilisation and daily hygiene.

Clinic owners in the area often make the same avoidable mistakes. Many delay repairs until a visible leak appears, when a crack injection at SAR 40–120 per metre is far cheaper than repairing water damage to finished walls and ceilings below. Others select a coating only by its lowest rate and overlook the substrate underneath, which can cause the new layer to peel within a short period. Some also skip the inspection of joints and corners, where movement is greatest. We recommend reviewing the tank, its supports and its connections before any coating is applied, so that the chosen material, whether epoxy at SAR 35–90 per m² or spray foam at SAR 20–45 per m², suits both the structure and the clinic's daily routine.

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

How we choose the tool in Alnuayriyah

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.
