What is specific about Afif for basement & foundation 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.. Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

The centre of Afif sits about 1040 m above sea level (SRTM open elevation data).

Before any quote is signed for basement or foundation waterproofing in Afif, it helps to start with the site itself. The centre of Afif sits about 1040 m above sea level (SRTM open elevation data), and that height matters for how a basement or foundation is judged. Start by asking how the ground around the building slopes, because water tends to collect where the land falls toward the structure. Check whether the basement wall is the first point of contact with that water, and whether any existing coating has already failed or been patched. Confirm the scope in the same terms the quote will use: basement waterproofing is priced per m², with a typical range of SAR 50–150 per m², while crack injection is priced per metre, at SAR 40–120 per m. Knowing which of these applies to your wall lets you compare quotes on the same basis.

Several things can only be judged on the day of the site visit. The technician should look at the wall surfaces for cracks, damp patches, efflorescence and any movement, and decide whether crack injection, a full coating, or a membrane is the right response. They should also check the drainage path around the foundation, the condition of the ground surface, and whether the basement lies below any nearby water source. Ask them to measure the exact area to be treated, rather than estimating from the plans. Where a coating system is suggested, the choice between epoxy coating (SAR 35–90 per m²), spray foam (SAR 20–45 per m²), or insulation boards such as XPS (SAR 12–30 per m²) should follow what the wall actually needs, not what is cheapest. Those decisions depend on conditions that only appear once the wall is open to inspection.

To help the technician, share the history of the property before the visit. Note when damp was first noticed, whether it appears after rain or all year, and any previous repairs or products used. Provide access to the basement and to the outside of the foundation so both faces can be examined. If the basement is used for storage or a water tank is present, mention it, since tank internal coating is priced separately at SAR 25–60 per m². Clear answers to these points let the technician give a realistic scope and a quote that reflects the real conditions of your building in Afif.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.
