Water tank waterproofing for restaurants in Riyadh
In short: In Riyadh (Riyadh), water tank waterproofing for restaurants 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 Riyadh sits about 637 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.

For restaurants in Riyadh, the most common problem with water tank waterproofing is leakage at the seams, joints and internal walls caused by constant heavy use. Commercial kitchens draw water all day, and tanks that are emptied and refilled often are subjected to repeated stress. Over time this can lead to cracking and seepage that is easy to miss until the stored water is affected. Tank internal coating is usually the first priority, typically priced at SAR 25–65 per m², because it protects the water itself as well as the structure around it.
Riyadh's local conditions shape how this work should be approached. The centre of the city sits about 637 m above sea level, and the dry, hot climate causes concrete and coatings to expand and contract with temperature swings. For that reason, a good approach looks at crack injection, priced at SAR 40–125 per metre, alongside the coating itself, rather than relying on a surface layer alone. Where tanks share a roof or sit beside other structures, liquid roof waterproofing at SAR 10–25 per m² or bitumen membrane at SAR 15–35 per m² may also be part of the plan. Epoxy coating, at SAR 35–95 per m², is another option for surfaces that need a tougher finish.
Before the visit, it helps to have a few details ready so the assessment is useful. Note the tank's capacity, its age, and whether it is above ground, at roof level or below the kitchen. Mention any visible cracks, damp patches or water taste changes, and say when the tank was last cleaned or recoated. Ask the provider to explain which materials they recommend and why, and to give a written quote that separates coating, crack repair and any surface preparation. Clear answers to these questions will help you compare options and keep your restaurant's water supply safe and reliable.
For restaurants, visits are planned outside service hours and recorded for the premises file.
When do you need water tank waterproofing?
These are the signs most often linked to water tank waterproofing:
- 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 — we check this before anything else.
- Construction joints — we check this before anything else.
Tools and methods, and when we use them
| 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 best thermal insulation material for a humid climate in the Eastern Province?
In humid areas, it is preferable to choose materials with low water absorption, such as extruded polystyrene or polyurethane foam, because they retain their efficiency in the presence of moisture. However, the final choice depends on the type of surface, the budget, and the contractor's recommendation after inspection.
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.
What is the first step of water tank waterproofing for restaurants?
We start with emptying and ventilation (the tank is emptied and ventilated before entry), then cleaning and preparation (loose material is removed down to a sound surface).
