What is specific about Jazan for floor & balcony waterproofing

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).

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..

In Jazan, floor and balcony waterproofing most often fails at the joints and edges where water is allowed to pool or soak back into the slab. The most common problem we see in this property type is water tracking under tiles and into the room below after heavy rain, usually through hairline cracks and along the junction between the balcony floor and the wall. Left alone, this turns into staining, flaking plaster and damp smells that are costly to repair later. A periodic preventive check is far cheaper than treating the damage once it has spread.

Local conditions change how the work should be approached. The centre of Jazan sits about 7 m above sea level, and the city is about 1.9 km from the sea coast. That combination means the site is low-lying but not flat in any way that drains quickly, so surface water can linger on balconies after storms, and humid coastal air keeps joints and sealants damp for longer. For these reasons we start by checking the drainage slope and outlets before recommending any coating, and we focus on sealing cracks and edges properly rather than only resurfacing the visible floor. The choice of system follows from what we find. Liquid roof waterproofing is typically priced at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and epoxy coating at SAR 35–90 per m², so the right solution depends on the surface, its movement, and how exposed it is.

Before the visit, ask for the exact location of the balcony or floor, whether leaks have appeared below, and when the problem was last seen after rain. Confirm whether there are visible cracks and how long they have been there, and whether any previous coating has been applied. Ask what the quotation covers, including crack injection at SAR 40–120 per metre if it is needed, and what preparation work is included. Finally, agree on a schedule for a repeat check so the surface is inspected regularly, not just after damage appears.

Preventive checks follow a written schedule instead of waiting for a fault.
