Why floor & balcony waterproofing differs in Jazan

The centre of Jazan sits about 7 m above sea level (SRTM open elevation data). Jazan is about 1.9 km from the sea coast (OpenStreetMap).

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..

An owner of a small clinic in Jazan often rents a ground-floor or upper-floor unit in a multi-storey building and wants the floors and balcony to stay dry, clean and usable for patients. Water that reaches a treatment room or waiting area can damage flooring, stain walls and create odours that patients notice straight away. Many owners only think about waterproofing once a leak has already appeared, and by then the repair often involves more of the floor than expected.

The local facts give useful context. The centre of Jazan sits about 7 m above sea level, according to SRTM open elevation data, and Jazan is about 1.9 km from the sea coast, according to OpenStreetMap. Being this close to the coast and only a few metres above sea level means that humid air, salt-laden moisture and standing rainwater can all play a part in how surfaces age. A balcony or floor that drains slowly or is not sealed properly may hold moisture for longer, so it is worth checking the falls and drainage before choosing a coating. Those conditions also make it sensible to compare the cost of different systems, since a bitumen membrane, liquid roof waterproofing and an epoxy coating each suit different surfaces and traffic levels.

A practical approach starts with a visual check of the floor and balcony edges for cracks, blistering or dark staining. Next, mark any cracks and have them injected or sealed, since crack injection is charged per metre and should be done before any surface coating. Then confirm the drainage slope and clear outlets so water leaves the area quickly. After that, choose the system that matches the use: epoxy coating for areas that need a hard-wearing, cleanable finish, spray foam or liquid roof waterproofing for exposed balconies, and a bitumen membrane where a continuous layer is needed. Finally, ask for a written price per square metre for each item and schedule the work outside clinic hours so patient areas are not disrupted.

For clinics, work is scheduled around patient hours and kept to the areas that need it.
