Water tank waterproofing for warehouses in Makkah
In short: In Makkah (Makkah), water tank waterproofing for warehouses 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 Makkah sits about 301 m above sea level (SRTM open elevation data). Published price: Tank internal coating (per m²), SAR 25–65 per m²; anything else is quoted after the inspection.
Water tank waterproofing in Makkah: the local context
The centre of Makkah sits about 301 m above sea level (SRTM open elevation data). Team note on Makkah: 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 Makkah sits about 301 m above sea level, according to SRTM open elevation data, and that height shapes where a technician starts when inspecting a warehouse water tank. Before any coating is discussed, the first check is the tank itself: its internal surface, the joints where walls meet the floor, and any cracks that could let water through. Basement waterproofing is quoted at SAR 55–160 per m², and tank internal coating at SAR 25–65 per m², so the scope of the inspection determines which of these rates applies. Crack injection, priced at SAR 40–125 per metre, is often needed at the same stage, so the technician notes every crack length before deciding anything else.
Several points are left to the site visit, because they cannot be judged from a description. These include the exact surface area of the tank, the condition of the existing lining, whether the tank is above or below ground, and how the warehouse roof drains into the tank. Roof options such as liquid roof waterproofing at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 15–30 per m² are compared only after the roof and any insulation needs are measured on site. Epoxy coating at SAR 35–95 per m² and spray foam at SAR 25–35 per m² are also weighed against what the surface can actually take, which only a visit can confirm.
To help the technician prepare, it is useful to have the tank's dimensions, its age, any past leaks or repairs, and photographs of visible cracks or stains ready before the visit. Information about the warehouse's stored goods matters too, since some materials need a different internal finish. Noting the roof area and the access route for materials will save time on the day. With these details in hand, the technician can match the right treatment to the tank and give a clear picture of the work involved.
For warehouses, work is phased around operations and stored goods.

Tools we use in Makkah
| Tool | What it finds | When we use it in Makkah |
|---|---|---|
| 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.

Questions from Makkah
What does finishing work typically include?
It covers plastering, painting, flooring, stone or marble walls, ceilings, gypsum, doors, windows, and final electrical and plumbing installations. You can request full or partial finishing, with the scope clearly defined in the price quote.
Is it possible to renovate the building without evacuating the residents?
In many cases it can be carried out in phases without a full evacuation if the damage is limited. However, for extensive structural renovation, a temporary evacuation may be recommended to ensure safety, and the contractor will explain this in their proposal.
Does waterproofing require removing existing tiles?
It depends on the site condition. Sometimes surface waterproofing can be applied over tiles, while deep leaks require tile removal to treat the layer underneath. A technician will determine the best option after inspection.
