What is specific about Khafji for water tank waterproofing

Team note on Khafji: 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.. Main roads in or near Khafji: King Abdullah Road.

The centre of Khafji sits about 9 m above sea level (SRTM open elevation data). Khafji is about 2 km from the sea coast (OpenStreetMap).

Water tanks at clinics are often the quiet weak point in a building's water system. The most common problem is seepage through hairline cracks and failed joints in the concrete walls and floor, which lets water migrate and contaminate stored supply. For a clinic, where hygiene is non-negotiable, even a slow leak or a damp, unhygienic interior can cause real trouble. A tank that looks sound from the top can still be losing water and harbouring growth on the inside.

Khafji's location shapes how we approach this work. The centre of the town sits about 9 m above sea level, and it is about 2 km from the sea coast, so the local ground and air carry salt and moisture that can speed up deterioration of exposed concrete. For that reason, tank internal coating is usually the starting point, with the work priced in the range of SAR 25–60 per m², and epoxy coating at SAR 35–90 per m² where the clinic needs a smooth, cleanable surface. Where cracks are present, crack injection at SAR 40–120 per metre is typically the first step, so the coating has a sound base to bond to. Tanks sit within a wider building, so the team should also check any adjoining bathroom or basement areas, which may use different materials and rates.

Before the visit, ask the provider for a written scope that names the tank's location, its approximate internal dimensions, and whether it holds potable water. Ask how they will drain, clean and dry the tank, and how long it will be out of service, so the clinic can plan around it. Request a clear breakdown of each item, such as crack injection, surface preparation and coating, so you can compare quotes line by line. Finally, ask whether the coating is suitable for drinking-water contact and how it will be checked once the work is complete.

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

Tools and methods, and when we use them

How the work is done, step by step

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.
