Water tank waterproofing in Madinah: cost & published offers
In short: Water tank waterproofing (cost & published offers) in Madinah starts with the fill test with level monitoring, then the crack injection (polyurethane or epoxy), before anything is opened. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Pricing starts from Tank internal coating (per m²) (SAR 25–60 per m²), and other items are quoted after the visit.
Before we start: what we know about Madinah
The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). 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..
How much does it cost to waterproof a water tank in Madinah, and what do the published offers cover? Tank work here is priced per square metre, and the range depends on the method and the surface. Internal tank coating is listed at SAR 25–60 per m², which is the figure most owners will compare first when they request a quote. Crack injection, which is often needed where a leak has been traced to a single seam, is priced separately at SAR 40–120 per metre. Because the rates vary this much, it helps to know the exact method before you ask for a price, rather than comparing a flat offer against a per-metre one.
The inspection starts with the tank itself. The technician checks the internal surface for cracks, flaking, and damp patches, and marks any seams that show signs of movement or seepage. Since the centre of Madinah sits about 589 m above sea level, the surrounding ground and the rooftop exposure can differ from site to site, so the inspector also looks at how the tank sits and how water reaches it. Where a crack is found, its length is measured in metres so that injection can be quoted accurately. The surface is then assessed for the coating type that suits it, whether epoxy, which is listed at SAR 35–90 per m², or a different system altogether. This stage is about establishing the scope, not yet carrying out the work.
Before the visit, gather the information that will shorten the assessment. Note when the leak first appeared, where it shows up, and whether it gets worse after rain or after the tank is filled. Measure or estimate the internal surface area and the approximate length of visible cracks, since these are the two figures that drive the quote. If the tank sits on the roof, also note whether the roof itself has been treated, because liquid roof waterproofing is listed at SAR 10–25 per m² and is often considered alongside the tank. Clear access to the tank and its cover, and make sure the water supply can be shut off during the inspection. With these details ready, the quote you receive will reflect your actual tank rather than a general estimate.

Signs worth paying attention to
The following signs are worth checking before they grow:
- A tank that leaks after testing
- Deposits and flaking inside the tank
- Unusual colour or taste in the water
Where the problem usually comes from
- Damaged old coating.
- Cracks in the walls or floor — we check this before anything else.
- Construction joints.
Tools and methods, and when we use them
| Tool | What it finds | When we use it in Madinah |
|---|---|---|
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Fill test with level monitoring | Whether a tank coating holds after the work | Limits: takes time to monitor the level |
| Crack injection (polyurethane or epoxy) | Stopping active water through cracks | Limits: treats the crack, not the water source |
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.
Where does water tank waterproofing (cost & published offers) start in Madinah?
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).
What does water tank waterproofing cost in Madinah?
From our published price list: Tank internal coating (per m²) SAR 25–60 per m². Quantities are confirmed at the inspection.
What do I receive after the work?
The material name, its batch number and the fill-test result, in a technical report that carries a verification code.
Common mistakes we see
- Using a material that is not intended for drinking water
What you receive
You receive: the material name, its batch number and the fill-test result, in a technical report with a verification code.
If you live in Madinah and are new to the area
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
