Water tank waterproofing in Baish: before buying or handover
In short: Water tank waterproofing (before buying or handover) in Baish starts with the fill test with level monitoring, then the crack injection (polyurethane or epoxy), before anything is opened. The centre of Baish sits about 84 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.
Why water tank waterproofing differs in Baish
Team note on Baish: 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 Baish sits about 84 m above sea level (SRTM open elevation data).
The centre of Baish sits about 84 m above sea level, according to SRTM open elevation data. For a water tank, that height matters less for the tank itself than for how water is supplied and stored in the area. Owners in a place like this often rely on rooftop or ground-level tanks to keep a steady supply, so the condition of the tank walls, base and lid is central to how reliably the water stays clean and dry in the surrounding structure.
Because the site is a set of fixed points on the terrain, the service has to be planned around the tank's actual location and access. A tank on a roof is exposed to sun and rain, so the liquid roof waterproofing, priced at SAR 8–25 per m², and bitumen membrane, at SAR 15–35 per m², are the typical options for the surfaces around it. A tank that sits in a basement or against a ground-level wall needs the basement waterproofing rate of SAR 50–150 per m², and the tank's internal lining is quoted separately at SAR 25–60 per m². Crack injection at SAR 40–120 per metre is usually the first step where a leak has already appeared, because it seals the line where water is entering.
Before you buy a property or accept a handover, check the tank rather than trusting the seller's word alone. Common mistakes owners avoid include: accepting a fresh coat of paint on the outside of a tank that still shows damp or staining inside; skipping a look at the base and the joints where walls meet the floor; and treating the roof surface above the tank as separate from the tank itself, when water running off a cracked roof can reach the tank cover. Ask for the work to be written as a per-square-metre price with the area measured, and confirm that internal coating of the tank is included in the quote rather than assumed.
Before buying or taking over a property, an inspection gives you findings in writing before you sign.
Signs worth paying attention to
The following signs are worth checking before they grow:
- Deposits and flaking inside the tank
- A tank that leaks after testing
- Unusual colour or taste in the water
Causes we see in the field
- A common cause: cracks in the walls or floor.
- Damaged old coating.
- A common cause: construction joints.
How we choose the tool in Baish
| Tool | What it finds | When we use it in Baish |
|---|---|---|
| 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 |
How the work is done, step by step
- 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.

Planning the visit in Baish
- 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.
- 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.
