Why water tank waterproofing differs in Taif

The centre of Taif sits about 1673 m above sea level (SRTM open elevation data). Team note on Taif: 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..

Picture an apartment owner in Taif who lives on an upper floor of a mid-sized building and relies on a rooftop water tank to keep the household supplied. The tank sits in the open air, the owner rarely looks at it, and the first sign of trouble is usually a damp patch on the ceiling below or a faint smell of stored water in the bathroom. By then the leak has often been running for some time, and the repair has grown from a small job into a larger one.

Taif is set high in the mountains, with its centre about 1673 m above sea level. That elevation brings cooler nights and more pronounced temperature swings than in the coastal cities, and the materials on a rooftop tank expand and contract with those swings every day. Over time, this movement opens hairline cracks at joints and corners. For an apartment owner, this means the tank and the roof beneath it deserve regular checks rather than occasional attention, because the stresses are constant and the damage is cumulative.

If you own an apartment in Taif, start by inspecting the tank and the surrounding roof surface after the cooler season, looking for cracks, lifted coatings and stains running down the walls. Next, decide which parts need attention: liquid roof waterproofing typically costs SAR 10–25 per m², a bitumen membrane SAR 15–35 per m², and the tank's internal coating SAR 25–55 per m². Crack injection, priced at SAR 40–115 per metre, can seal isolated defects before they spread. Then compare these figures with the scope of work a specialist proposes, and ask for the work to be done on the tank and roof together, since a sound tank can still leak through a failed roof surface below it.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.

When do you need water tank waterproofing?

If you notice one of these signs in Taif, it is a good moment to talk to the team:

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

Where the problem usually comes from

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