Before we start: what we know about Afif

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 hotels and serviced apartments in Afif usually starts with the same problem: a rooftop or ground-level tank that leaks slowly at the joints and cracks, and the damage stays hidden until guests notice stains, damp smells or a drop in water pressure. For hotels and serviced apartments, even a small leak can disrupt occupancy, so the aim is to find the source early and seal the tank before the problem spreads into ceilings and walls below.

Afif sits about 1040 m above sea level, which is a useful fact to keep in mind when planning the work. At that elevation the centre of town experiences conditions that can affect how coatings cure and how fast surfaces dry, so the team needs to check the tank surface, its moisture level and the weather window before choosing a system. Tank internal coating is typically priced at SAR 25–60 per m², while crack injection is SAR 40–120 per metre, so a clear survey of the cracks helps decide whether a full recoat or targeted repair is the more sensible route. Liquid roof waterproofing, at SAR 8–25 per m², and bitumen membrane, at SAR 15–35 per m², are also options where the tank sits under an exposed roof.

Before the visit, ask the provider which products they plan to use and why they suit a water tank in Afif rather than a general roof. Ask how they will locate the leak, whether they will drain and clean the tank first, and how long the tank will be out of service. Request a written quote that lists the area in square metres and any crack lengths in metres, so you can compare it against the price ranges above. Finally, ask how the hotel or apartment team will be kept informed during the work so that guest bookings and water supply can be planned around the job.

For hotels and serviced apartments, rooms are handled in batches to keep units available.
