Underground tank leak detection in Dammam: the local context

Dammam is about 4.3 km from the sea coast (OpenStreetMap). The centre of Dammam sits about 12 m above sea level (SRTM open elevation data).

Team note on Dammam: 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..

Underground tanks at villas in Dammam most often fail quietly. Water tanks, and sometimes fuel or greywater storage, lose contents through cracked walls, failed joints or corroded inlet and outlet fittings long before anyone sees a wet patch above ground. Owners usually notice only when pump run times climb, water bills rise without explanation, or the level drops faster than normal use would explain. Early detection saves both water and the cost of emergency excavation.

Dammam shapes how we approach these checks. The centre of Dammam sits about 12 m above sea level, so the ground around villas drains in a different way from low coastal sites, and water that does escape from a tank can track along the surrounding backfill rather than pooling visibly on the surface. Dammam is also about 4.3 km from the sea coast, which means salt-laden air and salty groundwater can reach buried concrete and steel over time. For that reason we pay close attention to the tank's internal coating and its condition, because a worn coating is one of the main routes for corrosion. Where recoating is needed, the internal coating is priced at SAR 25–60 per m², and the final figure depends on the tank's surface area and its condition on the day of inspection.

Before the visit, ask the provider how they will test the tank rather than only inspect it, and whether the method can work with the tank's depth and access. Confirm what happens if a leak is found, including whether the coating assessment is included and how the area will be measured. Ask who will be on site, how long they expect the check to take, and what written report you will receive afterwards. Clear answers to these questions help you judge whether the visit will tell you what you need to know about your villa's underground storage.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.

When do you need underground tank leak detection?

These are the signs most often linked to underground tank leak detection:

• Damp or salt marks on the tiles above the tank
• The tank needs refilling faster than usual
• The pump runs for longer periods
• A noticeable drop in the water level overnight

The most common causes

• Cracks in the concrete tank walls or floor.
• Construction joints and corners — we check this before anything else.
• A common cause: a float valve that does not close, so water is wasted.

Tools we use in Dammam

How the work is done, step by step

1. Safety first: Tank lids and confined spaces are handled with ventilation and a second person on site.
2. Documented level test: Filling and use are stopped and the level is recorded against time.
3. Isolating the tank from the network: This tells us whether the loss is from the tank body or from the supply line.
4. Checking the body and connections: Inlet, outlet and overflow connections are inspected.
5. Recommendation: You get the next step in writing: repair, waterproofing or a line test.

What we advise against

• Ignoring the float valve
• Waterproofing the tank before confirming the loss is from the tank and not the line
