Water tank waterproofing for warehouses in Abu Arish

Before we start: what we know about Abu Arish

Team note on Abu Arish: 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 Abu Arish sits about 67 m above sea level (SRTM open elevation data).

A typical owner of a warehouse in Abu Arish often has a large storage building with a water tank on the roof or beside the structure, and the tank is easy to forget until a leak shows up in the stock room below. The owner is usually focused on moving goods, keeping staff working and controlling costs, so the tank may only get attention when water stains appear on a wall or when the supply runs low. By then the damage has often spread, and the repair is larger than it needed to be.

The local facts matter here. The centre of Abu Arish sits about 67 m above sea level, which places the town on higher ground than the coastal areas nearby. That elevation does not remove the need for waterproofing, but it means owners should not assume that a tank in this area is safe from wear simply because it is away from the shore. Tank internal coating is priced at SAR 25–60 per m², and a tank that has been neglected may need that work sooner than the owner expects. Roof work is also a real cost to plan for, with liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m², so a warehouse roof that drains into or around the tank deserves a joint review.

A sensible approach starts with an inspection of the tank interior and the joints around it, looking for hairline cracks, rust, peeling coating and any wet patches on the walls below. Record the areas that need attention and measure them in square metres or metres of crack, since most quotes are built from those figures. Next, decide the order of work: seal active cracks first with crack injection at SAR 40–120 per metre, then prepare the internal surface and apply tank internal coating. Clear the roof of debris and fix any drainage faults before laying the chosen roof system. Finally, check the work with a fill test before the tank returns to full service, and keep a simple log of the date and the areas treated so the next inspection is quicker and cheaper.

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

Signs worth paying attention to

The following signs are worth checking before they grow:

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

The most common causes

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

How we choose the tool in Abu Arish

The steps in order

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.
3. Crack treatment: Active cracks are treated first.
4. Coating layers: A material intended for drinking-water tanks is applied.
5. Disinfection and fill test: The tank is disinfected and the level is monitored after filling.
