Water tank waterproofing in Jeddah: for companies (annual contract)
الخلاصة: In short: In Jeddah (Jeddah), water tank waterproofing (for companies (annual contract)) 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 Jeddah sits about 15 m above sea level (SRTM open elevation data).
Why water tank waterproofing differs in Jeddah
Team note on Jeddah: 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 Jeddah sits about 15 m above sea level (SRTM open elevation data).
Jeddah is about 2 km from the sea coast (OpenStreetMap).
Before any coating is quoted for a company water tank in Jeddah, the first thing to check is the tank's position relative to the coast. Jeddah is about 2 km from the sea coast, which means salt-laden air and groundwater can reach the structure and speed up corrosion of concrete and steel, so the technician should note the tank's exposure from the start. The centre of Jeddah also sits about 15 m above sea level, so the site should be read in terms of local drainage and whether water tends to collect around the tank base or pool on the roof. Together these two facts shape which surfaces are inspected first and how much attention the joints and edges will need.
The rest is left to the site visit, because only a person standing at the tank can judge its real condition. The technician will look for cracks, delamination, damp patches, failed sealant and any sign that the existing lining has lifted. They will also confirm the tank's material, size, access points and whether it holds potable water, since that affects which products are suitable. Where a repair is needed, the scope may range from crack injection at SAR 40–125 per metre to full tank internal coating at SAR 25–65 per m². Final pricing depends on what the inspection finds, so the visit is what turns a general estimate into a specific plan.
To help the technician arrive prepared, the client should make the tank's history available, including previous repairs, the age of the coating, and any recurring leaks. Clear access to the roof, the interior and the inlet and outlet pipes saves time on the day. It also helps to note whether the tank is shared with other buildings or sits on a rooftop that is used for other purposes. With this background, the technician can compare the likely options, such as epoxy coating at SAR 35–95 per m² or spray foam at SAR 20–45 per m², and recommend the one that fits the tank and the site.
For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
Signs worth paying attention to
If you notice one of these signs in Jeddah, it is a good moment to talk to the team:
- Unusual colour or taste in the water
- A tank that leaks after testing
- Deposits and flaking inside the tank
Where the problem usually comes from
- Construction joints.
- Damaged old coating.
- Cracks in the walls or floor — we check this before anything else.
Tools and methods, and when we use them
| Method | What it helps with | Its role in Jeddah |
|---|---|---|
| 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 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.
What is the first step of water tank waterproofing (for companies (annual contract))?
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).
How much does water tank waterproofing cost in Jeddah?
