Water tank waterproofing for apartments in Madinah
In short: In Madinah (Madinah), water tank waterproofing for apartments begins with the fill test with level monitoring and the crack injection (polyurethane or epoxy); nothing is opened until the position is clear. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Published price: Tank internal coating (per m²), SAR 25–60 per m²; anything else is quoted after the inspection.
Water tank waterproofing in Madinah: the local context
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).
An apartment owner in Madinah often notices a problem only when it is already visible: a damp patch on a bathroom wall, a stain spreading across a ceiling after rain, or a concrete tank on the roof that leaks into the flat below. Many owners in this situation are busy families or expats who rent out their units and want the water problem solved once, without repeated visits from workers. Water tanks on rooftops are a common source of trouble, and the leak may not be obvious until it reaches the living space.
Local conditions matter here. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data), so the city is well above the coast and the wider surrounding land changes in height. For an owner, this means that water flows across sloped ground and roofs and can find its way into cracks and joints over time. Good drainage on roofs and around the building, and sealing that holds up under changing conditions, are therefore worth planning rather than treating as an afterthought. Costs also vary by the area treated: basement waterproofing ranges from SAR 50–150 per m², while liquid roof waterproofing ranges from SAR 10–25 per m², so the first step is deciding exactly which surfaces need work.
A practical approach starts with inspection. Check the tank interior, the roof surface, bathroom floors and walls, and any cracks, noting where water appears. Next, repair the problems before coating: crack injection is priced at SAR 40–120 per metre, so seal visible cracks first, because a coating will not hold over a moving crack. Then choose the system for each surface. Bitumen membrane (SAR 15–35 per m²) suits roofs, epoxy coating (SAR 35–90 per m²) suits many concrete surfaces, and tank internal coating (SAR 25–60 per m²) protects the water store itself. Bathroom waterproofing runs SAR 15–40 per m². Finally, ask for a written plan showing each area, the method, and the total cost, and arrange a check after rain to confirm the work has held.
In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
Signs that call for water tank waterproofing
The following signs are worth checking before they grow:
- Unusual colour or taste in the water
- Deposits and flaking inside the tank
- A tank that leaks after testing
The most common causes
- A common cause: construction joints.
- Cracks in the walls or floor — we check this before anything else.
- Damaged old coating.
Tools and methods, and when we use them
| Tool | What it finds | When we use it in Madinah |
|---|---|---|
| Crack injection (polyurethane or epoxy) | Stopping active water through cracks | Limits: treats the crack, not the water source |
| Fill test with level monitoring | Whether a tank coating holds after the work | Limits: takes time to monitor the level |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
From the first visit to the report
- Emptying and ventilation: The tank is emptied and ventilated before entry.
- Cleaning and preparation: Loose material is removed down to a sound surface.
- Crack treatment: Active cracks are treated first.
- Coating layers: A material intended for drinking-water tanks is applied.
- Disinfection and fill test: The tank is disinfected and the level is monitored after filling.

Questions from Madinah
What is the difference between standard spraying and integrated pest management?
Standard spraying treats visible symptoms only, while integrated pest management includes diagnosis, sealing entry points, and multiple methods for longer-lasting results.
Could the leak be caused by weak waterproofing rather than the pipes?
Yes, damage to the waterproofing layer beneath the bathroom floor is one of the most common causes of leaks, especially in older buildings. In this case, water seeps through the tile joints into the screed and then down to the ceiling below. A specialized inspection can distinguish this from a pipe leak.
What is the difference between drain unblocking and drain cleaning?
Unblocking removes an existing blockage that prevents drainage, while cleaning is a preventive procedure that removes deposits and grease from pipes before they cause a blockage.
What is the first step of water tank waterproofing for apartments?
We start with emptying and ventilation (the tank is emptied and ventilated before entry), then cleaning and preparation (loose material is removed down to a sound surface).
