What is specific about Afif for water tank waterproofing

Team note on Afif: 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 Afif sits about 1040 m above sea level (SRTM open elevation data).

Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

Water tank waterproofing for rest houses and farms in Afif starts with the setting. The centre of Afif sits about 1040 m above sea level (SRTM open elevation data), so tanks here are often installed on higher ground where wind exposure, daily temperature swings and dry spells are part of normal life. The technician first checks how the tank is set up: whether it is elevated, sitting on a slab, or partly buried, and whether the rest house or farm uses it for drinking water, irrigation or both. These details decide which system suits the job and whether the coating must cope with constant sun on the exterior or only with water on the inside.

Some things can only be judged at the site visit. The technician looks at the existing surface, checks for cracks, flaking paint, old bitumen or salt marks, and confirms whether the tank is steel, concrete or fibreglass. Access, height and the condition of the base are assessed on the spot, as is whether a crack needs injecting before any coating goes on. Pricing for the work follows from those findings. For reference, crack injection runs SAR 40–120 per metre, tank internal coating runs SAR 25–60 per m², and liquid roof waterproofing runs SAR 8–25 per m², but the final figure depends on the measured area and the condition found, so the quote is only confirmed after inspection.

To help the technician, the owner or farm manager should have ready the tank's approximate size and height, the material it is made from, how old it is, and what water it holds. Any past repairs, leaks or lining work should be mentioned, along with photos of the tank and its surroundings if they can be sent in advance. Note the access route for vehicles and equipment, and whether the water supply can be shut off during the work. Clear answers to these points let the technician plan materials and time properly, so the visit can focus on the actual faults rather than on basic questions.

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