Before we start: what we know about Jazan

Team note on Jazan: 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.. Jazan is about 1.9 km from the sea coast (OpenStreetMap).

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

Jazan sits close to the Red Sea, about 1.9 km from the coast, and the centre of the city lies roughly 7 m above sea level. That closeness to salt-laden sea air and a humid coastal climate means insulation and waterproofing for hotels and serviced buildings have to cope with moisture and salt, not just heat. For owners and facility managers, this is the first practical reason to plan the building envelope with care, since a low-lying coastal site keeps damp in the ground and in the air around the structure.

Because the centre is only about 7 m above sea level, ground water and damp can sit closer to basements, ground-floor stores and service rooms than many visitors expect. Basement waterproofing, priced at SAR 50–150 per m², is therefore often the first line of defence for hotel plant rooms and warehouse storage below grade. Where moisture reaches through cracks, crack injection at SAR 40–120 per metre can stop leaks before they spread to stored stock or guest-facing areas. Roofs face the same sun and humidity, and liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² keeps water out of the insulation layer, which only works when it stays dry. Spray foam at SAR 20–45 per m² and XPS boards at SAR 12–30 per m² add thermal control, which helps keep cool air inside a serviced building rather than losing it through hot surfaces.

Owners tend to avoid a few predictable problems. The first is treating a coastal site like an inland one and skipping moisture checks at ground level, which lets damp undo the insulation. The second is leaving cracks unsealed and assuming the surface finish will hide them. The third is choosing cheap coatings for wet areas, where bathroom waterproofing at SAR 15–40 per m² and epoxy coating at SAR 35–90 per m² are better matched to heavy use. Finally, many owners avoid coating tanks and water storage without a proper internal finish at SAR 25–60 per m², since water left in contact with bare concrete causes lasting damage. Planning these layers together gives a dry, stable building for guests and stored goods alike.

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

Signs worth paying attention to

The following signs are worth checking before they grow:

• High heat that affects stored goods
• Leaks in a hangar or warehouse

Causes we see in the field

• Old insulation — we check this before anything else.
• A common cause: metal-sheet joints.
• Blocked gutters — we check this before anything else.
