What is specific about Taif for water tank waterproofing

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..

Is it worth waterproofing a water tank at a rest house or farm in Taif, and what does it cost? Taif is a high-altitude city, with its centre sitting about 1673 m above sea level, and many rest houses and farms there depend on rooftop and ground-level tanks that hold water through cool nights and hot days. A tank that leaks loses water you have already paid to pump or deliver, and a damp wall or slab can spread into the surrounding structure. For tank work, the internal coating is typically priced at SAR 25–55 per m², which is the figure most owners compare first when deciding whether to act now or wait.

Before any work starts, the inspection looks at where the water is escaping and what the tank is made of. The inspector checks the internal surfaces for cracks and damp patches, and where a crack is found, crack injection is priced at SAR 40–115 per metre. The roof above the tank is checked as well, since a leaking roof can feed water into the tank from outside, and liquid roof waterproofing is priced at SAR 10–25 per m² while a bitumen membrane runs SAR 15–35 per m². The inspector then recommends the coating or membrane that suits the findings, whether that is epoxy coating at SAR 35–85 per m², spray foam at SAR 25–45 per m², or XPS boards at SAR 10–30 per m² where insulation is also needed. Each option is quoted per square metre so the surfaces being treated are clear.

To make the visit efficient, prepare the basics. Clear access to the tank lid, the roof, and any ladder or stair route, and empty the tank as far as practical so surfaces can be seen dry. Note any past leaks, stains, or repairs, and have the approximate dimensions of the tank and roof ready so the measurements match the per-square-metre quotes. If the rest house or farm also has a basement or bathrooms with damp problems, mention them at the same time, since basement waterproofing is priced at SAR 50–145 per m² and bathroom waterproofing at SAR 15–40 per m². Gathering these details beforehand lets the inspection focus on what actually needs fixing.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.

Signs worth paying attention to

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

Causes we see in the field

• Construction joints.
• Damaged old coating — we check this before anything else.
• Cracks in the walls or floor — we check this before anything else.
