Water tank waterproofing in Afif: the local context

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.

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..

Is it worth waterproofing the water tank of an office block in Afif, and what will it cost? Water tanks on commercial roofs and in plant areas take constant stress from heat, pressure and seasonal moisture, and a leaking tank can quietly damage floors and ceilings below. In Afif, the centre sits about 1040 m above sea level (SRTM open elevation data), so the local climate and building conditions call for a careful look rather than a guess. For tank work, the most relevant rates are tank internal coating at SAR 25–60 per m², crack injection at SAR 40–120 per metre, and epoxy coating at SAR 35–90 per m². Cost depends on the tank's surface area, the number of cracks and the coating system chosen, so an on-site assessment is the only reliable way to set a figure.

The inspection starts with a walk-through of the tank exterior, the roof slab and the connecting pipework, looking for staining, efflorescence and hairline cracks. The inspector then examines the tank interior once it has been drained and cleaned, measuring the affected area and marking any cracks, joints and failed old coatings. Where cracks are active, the inspector notes their length in metres so that crack injection can be priced per metre. The surface is checked for moisture and loose material before any product is selected. The inspector also reviews the roof above the tank, since liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² may be needed to stop water reaching the tank from above. Once the findings are recorded, a written scope lists each area, the chosen system and the measured quantities.

Before the visit, the property owner should arrange access to the water tank, the roof and any plant room, and confirm when the tank can be emptied and kept out of use. It helps to share any past leak records, repair invoices and building plans, as these show where problems have occurred before. Make sure the building manager knows who will attend and that the office or tenants have been told about possible noise and short interruptions to water supply. Keep the tank's access ladder and hatch clear, and note any recent changes to the roof or pipework. With this information ready, the inspection can move straight to measuring and planning, and the owner receives a clear, itemised estimate for the work.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.
