Water tank waterproofing in Abu Arish: the local context

The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data). Team note on Abu Arish: 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..

Picture a homeowner in Abu Arish who is about to buy a villa, or who has just received keys from a builder. The roof has a rooftop water tank, the house has a bathroom or two, and there may be a small basement. The owner wants to know whether the tank and roofing are sound before money changes hands, and whether the seller's claims about waterproofing hold up. Nobody wants a surprise leak in the first rainy season, so the question is less about fancy materials and more about checking what is already there.

Abu Arish sits at about 67 m above sea level, which means the town is not on the coast-level flatlands but still well within reach of the moisture, heat and occasional heavy rain that affect buildings across the region. For an owner, this matters because roofs and tanks take the full weather load, and small defects become costly quickly. Local pricing gives a rough sense of what repairs can cost: liquid roof waterproofing typically runs SAR 8–25 per m², bitumen membrane SAR 15–35 per m², and tank internal coating SAR 25–60 per m². If a survey reveals that the tank lining has failed, the owner should treat this as a negotiating point rather than a minor detail. Basement waterproofing at SAR 50–150 per m² is a far larger job, so any sign of damp below ground deserves a closer look before handover.

A sensible sequence starts with the tank: drain it, inspect the inside for cracks, flaking coating and staining, and ask the seller for any previous repair records. Next, check the roof for ponding, cracked surface layers and failed joints, and note whether a membrane or liquid coating is already in place. Then move to the bathrooms, where floor and wall seals around showers and drains should be tested with water before the owner accepts the property. Mark every crack and measure its length, because crack injection is priced per metre at SAR 40–120 per m, and that figure helps compare quotes. Finally, agree in writing who pays for any defect found, and take photographs at handover so the condition is recorded.

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