Before we start: what we know about Dammam

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.. The centre of Dammam sits about 12 m above sea level (SRTM open elevation data).

Dammam is about 4.3 km from the sea coast (OpenStreetMap).

The first thing checked on a warehouse water tank in Dammam is its location, because the place itself shapes the risk. The centre of Dammam sits about 12 m above sea level (SRTM open elevation data), and the city is about 4.3 km from the sea coast (OpenStreetMap). Those facts mean the tank is not sitting in a low-lying coastal flood zone, so the technician looks first at the tank walls, floor, and joints for existing damage rather than assuming ground water is the cause of any leak. Salt-laden air and warm temperatures near the coast are a reason to check the condition of exposed external surfaces early in the inspection.

Several points can only be settled at the site visit. The technician needs to see the actual tank material, the depth of any cracks, whether water is seeping through joints or rising from the base, and how much of the interior coating has already failed. Access, the volume of water that must be drained, and whether the warehouse can be partly taken out of use during the work all depend on the layout on the day. Price ranges vary widely by method: internal tank coating is listed at SAR 25–60 per m², epoxy coating at SAR 35–90 per m², and crack injection at SAR 40–120 per metre, so the measured area and the number of cracks decide which combination is needed. None of these figures can be fixed until the surfaces are measured in person.

Information that helps the technician arrive prepared includes the tank's approximate size and construction, any previous repair records, and a note of where leaks have been noticed and when. If the tank roof is also exposed, the roof method matters separately: liquid roof waterproofing is listed at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², and XPS boards at SAR 10–30 per m², while spray foam sits at SAR 25–35 per m². Photos of the tank interior, the surrounding floor, and any staining on the walls are useful before the visit. Clear access routes and a safe place to drain or store water also save time on the day.

For warehouses, work is phased around operations and stored goods.

Signs that call for water tank waterproofing

The following signs are worth checking before they grow:

• Unusual colour or taste in the water
• A tank that leaks after testing
• Deposits and flaking inside the tank

The most common causes

• Construction joints — we check this before anything else.
• Damaged old coating — we check this before anything else.
• A common cause: cracks in the walls or floor.

Tools we use in Dammam

From the first visit to the report

1. Emptying and ventilation: The tank is emptied and ventilated before entry.
2. Cleaning and preparation: Loose material is removed down to a sound surface.
