Water tank waterproofing in Makkah: for companies (annual contract)
In short: Water tank waterproofing (for companies (annual contract)) in Makkah starts with the fill test with level monitoring, then the crack injection (polyurethane or epoxy), before anything is opened. 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.
Why water tank waterproofing differs in Makkah
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 (SRTM open elevation data).
For companies with annual water tank waterproofing needs in Makkah, the most common problem is seepage and corrosion at the tank's internal walls and joints. Water stored over a full year cycles through heat and cooling, and small cracks at the base and corners let moisture and sediment work into the concrete. The result is leaks that show up as damp patches on the slab below, staining, and gradual weakening of the structure. Companies often notice the problem only after water quality drops or a visible leak appears, which is why a planned annual inspection makes sense.
Makkah's setting changes how this work is approached. The centre of the city sits about 301 m above sea level (SRTM open elevation data), so the work is planned around the local climate and the way tanks are usually installed on rooftops or in service areas. Crack repairs are often priced per metre, with crack injection at SAR 40–125 per m, while internal lining is priced per square metre, with tank internal coating at SAR 25–65 per m² and epoxy coating at SAR 35–95 per m². Where a tank is also linked to a roof or a basement, liquid roof waterproofing at SAR 10–25 per m² or basement waterproofing at SAR 55–160 per m² may be part of the same plan. Insulation choices such as XPS boards at SAR 15–30 per m² can help manage temperature swings on exposed surfaces.
Before the visit, ask the provider to confirm the tank's size, material, and access points, and to explain which surfaces they expect to treat and why. Ask how they will drain, clean and dry the tank, and what the coating system is. Request a clear breakdown of the per-square-metre and per-metre rates that apply to your job, and ask how any cracks will be measured and recorded. Finally, ask for a written schedule for the annual inspection so your company can budget for upkeep across the year rather than reacting to emergencies.
For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
When do you need water tank waterproofing?
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
- Cracks in the walls or floor — we check this before anything else.
- Damaged old coating — we check this before anything else.
- A common cause: construction joints.
Tools we use in Makkah
| Method | What it helps with | Its role in Makkah |
|---|---|---|
| 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.

Common questions about water tank waterproofing in 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.

Planning the visit in Makkah
- 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.
