Floor & balcony waterproofing in Jazan: the local context

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).

Does a hotel or serviced apartment in Jazan really need a separate waterproofing check for its floors and balconies? For many owners the answer is yes, and the local setting explains why. The centre of Jazan sits about 7 m above sea level (SRTM open elevation data), and the city is about 1.9 km from the sea coast (OpenStreetMap). That combination of low elevation and nearby coastal air means moisture and salt can work into slabs and balcony edges, so a floor that looked fine last season may need a fresh look before guests notice a problem.

Our inspection starts with a walk-through of every floor and balcony in the property, looking for cracks, blistering, ponding water, and staining on ceilings below. Where a crack is found, we measure its length so the cost can be set out per metre, since crack injection is priced at SAR 40–120 per m. We then check the surfaces that take the most water, such as bathrooms and balconies, and note the area in square metres so each option can be priced on its own basis. Bathroom waterproofing is priced at SAR 15–40 per m², and balcony and roof areas can be quoted separately for liquid roof waterproofing at SAR 8–25 per m² or bitumen membrane at SAR 15–35 per m². Where the surface is wet and a coating is not suitable, we explain whether spray foam (SAR 20–45 per m²) or epoxy coating (SAR 35–90 per m²) would fit better. The result is a written list of areas, methods and rates, not a single lump sum.

Before the visit, it helps to gather a few things so the inspection is quick and the quote is accurate. Please prepare a floor plan or rough sketch showing bathrooms, balconies and any area above a basement or water tank, and note the floors that have had leaks or repairs before. Let us know if the property has a basement, since basement waterproofing is priced at SAR 50–150 per m², and whether any internal water tanks need attention, which is priced at SAR 25–60 per m². Having these details ready lets the visit focus on the surfaces that matter most to your guests and your building.

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