Floor & balcony waterproofing for villas in Jazan

Before we start: what we know about 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..

Floor and balcony leaks in villas are most often traced to hairline cracks and failed joints at the edges, where water sits under tiles and slowly works into the slab below. By the time staining shows on a ceiling, the damage has usually been spreading for some time. For this property type, the first step is checking where water actually collects, not just resurfacing the visible tiles.

Jazan's location shapes how that check is done. The centre of the city sits about 7 m above sea level, and it lies about 1.9 km from the coast. That combination means damp air, salt-laden moisture and heavy seasonal rain all reach the building fabric, so a waterproofing layer that works in a dry inland city may be tested harder here. A good approach therefore starts with a survey of the balcony drainage slope, the upstand at the wall junction and any existing cracks, before choosing between an epoxy coating, a bitumen membrane or crack injection. Each option is priced differently, with epoxy coating at SAR 35–90 per m² and bitumen membrane at SAR 15–35 per m², so the survey should explain which system suits the exact area and why.

Before the visit, ask the provider to confirm what they will inspect and how the surface will be prepared, since adhesion depends on it. Ask whether they will measure the area and give a written quote per m² and per metre for any crack injection, rather than a single lump sum. Ask which materials they plan to use, how the balcony edge and drainage outlets will be sealed, and what the cleaning and curing steps involve. Finally, ask for photographs of any damage found and a clear note of anything that will not be covered. Clear answers to these questions show whether the visit will actually find the source of the leak.

In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.
