What is specific about Alqunfudhah for floor & balcony waterproofing

Team note on Alqunfudhah: 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.. Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

The centre of Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).

Alqunfudhah sits about 7 m above sea level, and its centre is roughly 0.4 km from the coast. That combination matters for floors and balconies. Sea air carries salt and humidity, which can speed up corrosion of exposed reinforcement and keep surfaces damp longer after rain. Because the town is low and close to the water, moisture can also sit beneath slabs and in ground-level spaces, so the surfaces we treat need to resist both driving damp and salt-laden air. For owners, this means choosing a system suited to the exposure, not just the cheapest option on the quote.

The local geography shapes the work in practical ways. Being only about 7 m above sea level means water tends to collect rather than run quickly away, so balcony falls and drainage points are checked before any coating goes on. Proximity to the coast of about 0.4 km means exposure to salt spray, which is why surface preparation and the choice of coating matter more here than in an inland city. Where the fabric shows cracks, the crack injection rate of SAR 40–120 per metre is often used before the main membrane, because sealing a crack first stops moisture reaching the slab beneath the finish. Published rates for the main systems in the area include epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², liquid roof waterproofing at SAR 8–25 per m², and bitumen membrane at SAR 15–35 per m².

Owners in Alqunfudhah often avoid several common mistakes. The first is skipping crack repair and coating over a moving or open crack, which lets water return within months. The second is treating a balcony or terrace as flat when it needs a proper fall to drain, so water pools at the edge. A third is choosing a thin, low-cost finish for a damp area such as a bathroom, where bathroom waterproofing at SAR 15–40 per m² should be applied with upturns at the walls. Others leave insulation out of the plan, when XPS boards at SAR 12–30 per m² can help protect a roof from heat and moisture together. Finally, many owners do not ask for a clear statement of what the quote covers, including surface preparation and the number of coats. Asking for that detail before work starts protects the result.

Signs worth paying attention to

The following signs are worth checking before they grow:

• Damp under the light well
• A wrong fall towards the door threshold
• Water passing from the balcony to the floor below

The most common causes

• A blocked drain — we check this before anything else.
• Incorrect falls — we check this before anything else.
• A common cause: a threshold without waterproofing.

Tools and methods, and when we use them

How the work is done, step by step

1. Checking the falls: Where water collects and where it should go.
2. Details: Thresholds, drains and upstands.
3. Waterproofing: The layer is applied and protected.
4. Flood test: Tested before the finish goes on.
