Underground tank leak detection in Jeddah: for companies (annual contract)
In short: In Jeddah (Jeddah), underground tank leak detection (for companies (annual contract)) begins with the documented tank level test and the pressure test and line isolation; nothing is opened until the position is clear. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data). Published price: Inspection visit, SAR 150 per visit; anything else is quoted after the inspection.
What is specific about Jeddah for underground tank leak detection
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).
Is an underground fuel tank on your Jeddah site quietly leaking, and how would you ever know? For a company running fuel storage, that question matters more than most. Jeddah is a low-lying city where the centre sits about 15 m above sea level, and the coast is only about 2 km away. Ground conditions near the water can shift how groundwater moves around buried tanks, which is one reason an annual check is a sensible habit rather than a one-off task.
A leak detection visit normally starts with a review of the tank records, the fill and dispensing history, and any stock discrepancies your team has noticed. The inspector then checks the tank's condition, the piping, and the monitoring equipment that is already installed. Where internal coating is part of the picture, the cost is often estimated per square metre, and the rate for internal coating typically falls in the range of SAR 25–65 per m². That range depends on the size and condition of the tank, so the figure you receive should always come from a site-specific assessment rather than a generic quote. Findings are then recorded so that the next annual inspection can be compared against them.
Before the inspector arrives, gather the documents that show how the tank has been used and maintained. Useful items include past inspection reports, delivery and dispensing logs, stock reconciliation sheets, and records of any repairs or coating work. Note any recent changes in fuel usage, unexplained shortfalls, or odours near the site, since these details help the inspector focus their time. Make sure access to the tank area, the dispensing equipment, and the monitoring panels is clear and that a site contact is available during the visit. Preparing this material in advance keeps the inspection efficient and gives you a clearer picture of your tank's condition across the year.
For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
Signs that call for underground tank leak detection
If you notice one of these signs in Jeddah, it is a good moment to talk to the team:
- A noticeable drop in the water level overnight
- The pump runs for longer periods
- The tank needs refilling faster than usual
- Damp or salt marks on the tiles above the tank
The most common causes
- A common cause: a float valve that does not close, so water is wasted.
- Construction joints and corners.
- Cracks in the concrete tank walls or floor.
Tools we use in Jeddah
| Method | What it helps with | Its role in Jeddah |
|---|---|---|
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
| Pressure test and line isolation | Which line (hot/cold, floor by floor) loses pressure | Limits: needs working valves to isolate lines |
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
| Ground microphone and contact listening | The sound of water escaping under pressure in walls and floors | Limits: weaker with background noise and deep lines |
From the first visit to the report
- Safety first: Tank lids and confined spaces are handled with ventilation and a second person on site.
- Documented level test: Filling and use are stopped and the level is recorded against time.
- Isolating the tank from the network: This tells us whether the loss is from the tank body or from the supply line.
- Checking the body and connections: Inlet, outlet and overflow connections are inspected.
- Recommendation: You get the next step in writing: repair, waterproofing or a line test.

Common questions about underground tank leak detection in 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 underground tank leak detection (for companies (annual contract))?
We start with safety first (tank lids and confined spaces are handled with ventilation and a second person on site), then documented level test (filling and use are stopped and the level is recorded against time).
How much does underground tank leak detection cost in Jeddah?
From our published price list: Inspection visit SAR 150 per visit; Tank internal coating (per m²) SAR 25–65 per m². Quantities are confirmed at the inspection.
What do I get at the end?
The written level-test result and the recommended next step, in a technical report that carries a verification code.
What we advise against
- Waterproofing the tank before confirming the loss is from the tank and not the line
- Ignoring the float valve

Practical notes for residents of Jeddah
- You can message us on WhatsApp in English; the booking details are sent back to you in the chat to confirm before the visit.
- The Saudi weekend is Friday and Saturday; mention your preferred day and time when booking.
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- 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).
