Water tank waterproofing for restaurants in Jeddah
In short: Water tank waterproofing for restaurants in Jeddah starts with the fill test with level monitoring, then the crack injection (polyurethane or epoxy), before anything is opened. The centre of Jeddah sits about 15 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 Jeddah
The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data). Jeddah is about 2 km from the sea coast (OpenStreetMap).

Does a restaurant water tank in Jeddah really need waterproofing, given how dry the city can feel? The answer is yes, and the local geography is part of the reason. The centre of Jeddah sits about 15 m above sea level, and the city lies roughly 2 km from the coast. Those facts mean tanks and the structures around them face a mix of coastal humidity, salt-laden air and heat, all of which can wear down concrete and sealants over time. For a restaurant, a leaking tank is not only a building problem but a hygiene and service risk, so the question is less whether to act and more when and how.
Our inspection for a water tank in a restaurant starts with a walk around the tank and its supporting slab to look for cracks, damp patches, staining and any signs of past repairs. The technician then checks the tank's internal surfaces where access allows, since leaks often start inside before they show outside. Where cracks are found, the likely fix is crack injection, which is priced per metre at SAR 40–125 per m, and the length of each crack is measured so the quote reflects the actual work. For the tank interior, tank internal coating is priced at SAR 25–65 per m², and epoxy coating at SAR 35–95 per m² is one option for surfaces that need a tougher finish. Each finding is recorded so you can see exactly what is recommended and why.
Before the visit, it helps to have the tank's location, its accessible dimensions and any previous repair records to hand. Please note the current state of the water supply and any days when the kitchen can spare the tank from use, since some work needs the tank emptied and dried first. If there is a roof tank, it is useful to know whether the roof already has a membrane or liquid coating, because liquid roof waterproofing at SAR 10–25 per m² and bitumen membrane at SAR 15–35 per m² are different approaches. Clear notes on these points let the inspection focus on the problems that matter to your restaurant.
For restaurants, visits are planned outside service hours and recorded for the premises file.
When do you need water tank waterproofing?
The following signs are worth checking before they grow:
- A tank that leaks after testing
- Deposits and flaking inside the tank
- Unusual colour or taste in the water
Where the problem usually comes from
- Damaged old coating — we check this before anything else.
- Cracks in the walls or floor.
- Construction joints.
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 |
| 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 |
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.

Questions from Jeddah
Can I use household chemicals instead of calling a technician?
Using unsuitable chemicals may corrode pipes and does not fix the root cause of the blockage, so it is better to rely on a specialist technician.
What is the difference between foam insulation and other types of insulation?
Foam insulation is easy to apply on uneven surfaces and forms one continuous layer with no joints, while other types, such as bitumen rolls, need the joints to be welded. The contractor decides which is most suitable after inspecting the site.
Can thermal insulation be applied to an existing building?
Yes, thermal insulation can be installed on the roofs and walls of existing buildings without the need for major structural modifications. The contractor prepares the surface, then applies the insulating material and the protective layer over it.
Where does water tank waterproofing for restaurants start in Jeddah?
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).
What does water tank waterproofing cost in Jeddah?
From our published price list: Tank internal coating (per m²) SAR 25–65 per m². Quantities are confirmed at the inspection.
What do I receive after the work?
The material name, its batch number and the fill-test result, in a technical report that carries a verification code.
Mistakes that cost more
- Using a material that is not intended for drinking water
What you get after the work
The written output: the material name, its batch number and the fill-test result. The report is numbered and can be checked with its verification code.
Practical notes for residents of Jeddah
- 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.
- 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.
