Floor & balcony waterproofing in Khafji: the local context

The centre of Khafji sits about 9 m above sea level (SRTM open elevation data). Khafji is about 2 km from the sea coast (OpenStreetMap).

Team note on Khafji: 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 Khafji: King Abdullah Road.

Ponding water and failed joints on villa floors and balconies are the most common problems we see in Khafji. Balconies and terraces are usually where water first gets through, because the surface is exposed to direct sun, wind-driven rain and daily temperature swings, which crack old sealant and lift tiles. Once water reaches the slab, it can travel along the structure and appear as staining or damp patches in rooms below. Early signs include hairline cracks near drains, hollow-sounding tiles and paint bubbling along the ceiling edge.

Khafji sits about 9 m above sea level, and its centre is about 2 km from the coast. That combination shapes how we approach each job. Because the town is not far from the sea, the salt-laden air and humidity around the coast are a real factor, so we look closely at the surface finish and the joints rather than assuming a standard system will do. The modest elevation means rainwater drains off the site but still needs a clear route to the outlets, so we check falls and drain positions before any coating is chosen. Options such as liquid roof waterproofing, bitumen membrane, spray foam and epoxy coating are each weighed against the actual condition of the slab and the exposure of the balcony or roof.

Before the visit, ask the provider which system they propose for your specific surface and why, and what preparation is included. Ask whether crack injection is needed along any visible cracks, and how they will treat drains and upstands. Request a per-m² breakdown of the rates they are quoting, so you can compare, for example, liquid roof waterproofing at SAR 8–25 per m² against bitumen membrane at SAR 15–35 per m². Also ask who will inspect the work afterwards and how long the surface should be kept clear of traffic while it cures.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.
