Water tank waterproofing in Madinah: for companies (annual contract)
In short: Water tank waterproofing (for companies (annual contract)) 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). Published price: Tank internal coating (per m²), SAR 25–60 per m²; anything else is quoted after the inspection.
What is specific about Madinah for water tank waterproofing
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..
For companies in Madinah, the most common problem with water tank waterproofing is seepage through cracked or aged internal surfaces, which lets water into the stored supply and can cause corrosion and contamination over time. Tanks on company premises often run continuously and are seldom opened for inspection, so small leaks go unnoticed until staining, damp patches or a drop in water quality appears. Tank internal coating is typically priced at SAR 25–60 per m², and crack injection at SAR 40–120 per metre, so early attention to small faults is usually the more economical route.
Local conditions shape the approach. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data), so the surrounding terrain and drainage differ from coastal sites, and rainwater run-off should be checked around the tank base and feed lines before any coating work begins. Surface preparation matters in a warm, dry climate where existing coatings can become brittle and lift from the substrate. For roofs that support a tank, liquid roof waterproofing at SAR 10–25 per m² or a bitumen membrane at SAR 15–35 per m² may be considered, while epoxy coating at SAR 35–90 per m² is often chosen for internal tank surfaces that must remain sound and easy to clean.
Before the visit, ask the provider to confirm the tank capacity, material, age and any known leak history, and to state whether the inspection covers the internal walls, floor, roof and inlet and outlet fittings. Request a written breakdown of the work by area and method so you can compare the rate per m² against the ranges above. Ask how the tank will be drained, cleaned and refilled, and how long it will be out of service for your operations. Finally, confirm who will be on site, how access to the premises will be arranged, and what follow-up checks will be made after the work is finished.
For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

- Unusual colour or taste in the water
- A tank that leaks after testing

- Cracks in the walls or floor — we check this before anything else.
Tools we use in Madinah
| Method | What it helps with | Its role in Madinah |
|---|---|---|
| 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 |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
The steps in order
- 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.

Short answers for 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.
