Underground tank leak detection for warehouses in Jeddah
In short: In Jeddah (Jeddah), underground tank leak detection for warehouses begins with the documented tank level test and the pressure test and line isolation; nothing is opened until the position is clear. Jeddah is about 2 km from the sea coast (OpenStreetMap). Pricing starts from Inspection visit (SAR 150 per visit), and other items are quoted after the visit.
Before we start: what we know about 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.. Jeddah is about 2 km from the sea coast (OpenStreetMap).
The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data).
Jeddah sits on the Red Sea coast, and the centre of the city rises about 15 m above sea level, so the land is only gently elevated above the water. The city is also about 2 km from the sea coast. This combination matters for underground tanks in warehouse districts. Low, flat ground near the coast means that groundwater can sit close to the surface, and a leak can spread through the soil and reach water quickly. Our detection work starts with a close look at where a tank sits relative to the water table and the nearby coastline, so that monitoring wells and sensors are placed where they will catch a problem early rather than after it has moved far.
Each of these location facts changes how the service is delivered. Because the site is close to the sea and sits at a low elevation, we pay particular attention to salinity and moisture in the surrounding soil, since both can mask or mimic signs of a leak in readings. Warehouses in this part of the city often have heavy vehicle access and frequent deliveries, so tank lines and fill points are checked as part of the same visit. The tank internal coating is priced at SAR 25–65 per m², and the final figure depends on the tank surface area and the condition of the existing lining. We calculate this per project after inspection, so owners see the cost in relation to the real size of their tank rather than a generic estimate.
Owners in this area often make the same few mistakes, and most of them are easy to avoid. The first is waiting for a strong smell or a visible puddle before arranging any check, when by then the soil may already be affected. The second is assuming that a tank in a dry, inland-looking site is safe because the coast is only 2 km away, which overlooks the shallow groundwater that the coastal setting creates. The third is treating the coating as a one-time job and never reviewing it, even though the lining wears over time. Regular monitoring, prompt review of any sensor alert, and a clear record of tank condition are the habits that keep a warehouse tank dependable in Jeddah.
For warehouses, work is phased around operations and stored goods.
Signs worth paying attention to
The following signs are worth checking before they grow:
- The pump runs for longer periods
- A noticeable drop in the water level overnight
- Damp or salt marks on the tiles above the tank
- The tank needs refilling faster than usual
Causes we see in the field
- A common cause: a float valve that does not close, so water is wasted.
- Cracks in the concrete tank walls or floor.
- Construction joints and corners — we check this before anything else.
Tools we use in Jeddah
| Tool | What it finds | When we use it in Jeddah |
|---|---|---|
| Pressure test and line isolation | Which line (hot/cold, floor by floor) loses pressure | Limits: needs working valves to isolate lines |
| Documented tank level test | Level drop in numbers against time | Limits: filling and use must stop for a while |
| Ground microphone and contact listening | The sound of water escaping under pressure in walls and floors | Limits: weaker with background noise and deep lines |
| Moisture meter | How far the wet area spreads behind paint and tiles | Limits: measures the effect, not the source |
The steps in order
- 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.

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 underground tank leak detection for warehouses?
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.
Mistakes that cost more
- Ignoring the float valve
- Waterproofing the tank before confirming the loss is from the tank and not the line
What you receive
You receive: the written level-test result and the recommended next step, in a technical report with a verification code.
