Why water tank waterproofing differs in Alqunfudhah

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

Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

Alqunfudhah sits on the coast of Saudi Arabia, with its centre about 7 m above sea level, and its edge only about 0.4 km from the sea coast. For hotels and serviced apartments, this combination means the town is low-lying and close to salt-laden sea air. Water tanks here are exposed to humidity and salt that can attack concrete and metal surfaces over time, so the tank lining and seals must be chosen with that coastal environment in mind.

Because the centre is just 7 m above sea level, the ground is relatively flat and drainage around rooftop and ground-level tanks needs careful planning. Water that pools near a tank base can seep into joints and weaken the protective layer. Our tank waterproofing work therefore starts with checking the surrounding slope and drainage, and then matching the coating to the exposure. Internal tank coating is priced at SAR 25–60 per m², and the closeness to the sea is a reason to inspect the coating thoroughly at every service visit rather than waiting for visible leaks.

Owners of hotels and serviced apartments in Alqunfudhah often avoid a few common mistakes. They do not wait for a small crack to become a leak, since crack injection is priced at SAR 40–120 per metre and is far cheaper than repairing water damage to guest areas. They also avoid using a single generic product across every surface, because liquid roof waterproofing at SAR 8–25 per m² suits open roofs while epoxy coating at SAR 35–90 per m² suits the inside of a tank. Finally, they avoid skipping inspection after the seasons when humidity and salt air are highest, as a short check keeps a coastal property running smoothly for guests.

For hotels and serviced apartments, rooms are handled in batches to keep units available.

When do you need water tank waterproofing?
