Water tank waterproofing in Riyadh: the local context
Main roads in or near Riyadh: King Fahd Road, King Abdullah Road, King Abdullah. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data).
Team note on Riyadh: 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..
Riyadh's hot, dry climate means that tanks and the concrete around them face strong daytime heat and sharp temperature swings, which can open small cracks over time. The local rates listed for this service run from 55 to 160 riyals per square meter for basement wall treatment, from 15 to 40 riyals per square meter for bathroom or balcony insulation, and from 10 to 30 riyals per square meter for protective or reflective coating. For an apartment tank, the first thing checked is the condition of the existing concrete and the joints, because a coating applied over a damaged base will fail quickly under heat. The team also looks at whether the surface is sound enough to take a new layer, and that inspection decides how much preparation the job needs before any material goes on.
Before the visit, it helps to clear access to the tank area and note any past leaks, damp patches, or repairs you remember. Tell the team how the tank is used and whether it sits on the roof, in a utility room, or in a shared area, since that affects the work plan. Ask them how long the surface must dry before the tank is returned to service, and whether an epoxy layer can be applied over your existing concrete. Also ask which protective or reflective coating they recommend for the sun exposure on your building, and get the scope and price range written down before work begins.
In apartment buildings, the floor below is often where a leak shows first.

- Damaged old coating.
- Construction joints — we check this before anything else.
Tools we use in Riyadh
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| 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 |
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 Riyadh
What is the drying time for the floor before use?
The drying time varies depending on the system type, layer thickness, and site temperature. The installer will specify it within the scope of work.
Does detecting bathroom leaks require breaking tiles?
Usually not. Modern tools such as thermal cameras, electronic listening devices, and pressure testing pinpoint the source of a leak with high accuracy. If breaking is necessary, it is limited to the repair point only, after the location has been confirmed.
