What is specific about Madinah for water tank waterproofing

Team note on Madinah: 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 Madinah sits about 589 m above sea level (SRTM open elevation data).

The first thing a technician checks for a clinic water tank in Madinah is the elevation of the site and what that means for pressure and drainage. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data), so tanks are typically fed by pumps rather than gravity, and a clinic needs its supply and overflow lines checked before any coating work begins. Water that is pumped hard and dropped into a tank can stress joints and fittings, so the inlet, outlet and overflow points are inspected first. If a tank has been leaking at a seam, the technician notes the location and the wall it runs along, because a crack that repeats on the same side of a tank often points to a structural or pressure issue rather than a coating failure alone.

Some points can only be settled at the site visit. The technician must see the tank in person to judge whether the existing lining is sound, whether it can be overcoated, or whether it must be stripped back to the concrete. The size and condition of cracks are measured on the spot, since crack injection is priced per metre (SAR 40–120 per m) and the true length is only known once the surface is cleaned and dry. Access, the condition of the tank floor, and whether the clinic can drain the tank for a set period are also confirmed on site. Rates for tank internal coating (SAR 25–60 per m²) and epoxy coating (SAR 35–90 per m²) vary with the surface, so the final scope depends on what the visit reveals rather than on the first call.

To help the technician arrive prepared, the clinic should have ready the tank's dimensions, its age, and any earlier repair records, along with a note of when leaks were first noticed and whether they worsen when the pumps run. Access to the roof and the tank lid should be cleared in advance, and staff should know when the tank can be emptied without disrupting patient care. Where the tank sits on a roof, the liquid roof waterproofing option (SAR 10–25 per m²) and bitumen membrane (SAR 15–35 per m²) are both discussed on site, and any XPS boards (SAR 10–30 per m²) used for insulation are noted separately. Clear answers to these questions let the technician plan the work once and keep the clinic's water supply running with minimal interruption.

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

Signs that call for water tank waterproofing

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.
• A common cause: cracks in the walls or floor.
• A common cause: damaged old coating.

Tools and methods, and when we use them

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.
