Bathroom waterproofing for schools in Afif

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.

The centre of Afif sits about 1040 m above sea level (SRTM open elevation data), which places the town on a high plateau in the Najd region. Buildings here are exposed to a wide daily temperature swing, and the dry air can cause surfaces to expand and contract. For schools, this means bathroom floors and walls work hard over the year, so the waterproofing system must stay flexible as well as watertight.

That elevation shapes the way we plan a bathroom job for a school. Because the centre of Afif sits about 1040 m above sea level (SRTM open elevation data), we check for hairline cracks in older block walls and screed before any coating goes on, since temperature change tends to widen them over time. Our bathroom waterproofing (per m²): SAR 15–40 per m² covers surface preparation, primer and the membrane itself, and the quote is scoped room by room so that wet areas such as shower bays and washing channels receive the most attention. Where a crack is found, crack injection (per metre): SAR 40–120 per m is priced separately so the school sees exactly what is being repaired before the coating is applied.

Owners of school buildings in Afif often avoid a few predictable mistakes. Coating over a damp or dusty surface is the first, because the membrane will not bond and will lift within a season. Skipping the crack check is the second, since a small split left unsealed will carry water straight through the new layer. Many owners also choose a thin product to save money and then find the floor pools water at the drain. Planning the work for a term break, rather than during lessons, and keeping the bathrooms out of use until the coating has fully cured, prevents the most costly rework of all.

For schools, the larger jobs are planned for weekends and holidays.
