Water tank waterproofing in Buraydah: before buying or handover

Before we start: what we know about Buraydah

The centre of Buraydah sits about 606 m above sea level (SRTM open elevation data). Team note on Buraydah: 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..

Before buying or handing over a water tank in Buraydah, the first thing to check is the setting itself. The centre of Buraydah sits about 606 m above sea level (SRTM open elevation data), so the city is on high ground that is far from the coast, and the tank will see strong sun, wide temperature swings and dry air for much of the year. Those conditions matter for the coating, because heat and dryness speed up surface cracking and make poor adhesion show up sooner. Start by looking at the tank walls, lid and joints for existing cracking, flaking or old patch work, and ask the seller or landlord when the tank was last coated and with what product.

What is left to the site visit is the part that cannot be judged from a brochure. A technician needs to see the actual surface, measure its area, and decide whether the damage is shallow or runs through the wall. Crack repair is priced per metre, so the length of every crack must be walked and marked, while the coating itself is priced per square metre, so the internal and external areas must be measured separately. For reference, tank internal coating is typically SAR 25–55 per m², epoxy coating SAR 35–85 per m², and crack injection SAR 40–115 per metre, and the final figure depends on which of these the inspection shows is needed. If the tank sits partly below ground, the basement waterproofing range of SAR 50–145 per m² may also apply, so check how much of the structure is buried.

Information that helps the technician includes the tank's material, its approximate capacity, how old it is, whether it has ever held water with a visible leak, and whether the roof above it has been waterproofed. Note any previous repair products and whether the water inside is drinking water, since that affects which coatings are suitable. Share photographs of the cracks and stains and the dimensions of the tank if you have them. This lets the technician quote accurately, recommend a method that suits the surface, and avoid return visits.

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