Epoxy coating & waterproofing in Jubail: the local context

Jubail is about 0.9 km from the sea coast (OpenStreetMap). The centre of Jubail sits about 4 m above sea level (SRTM open elevation data).

Team note on Jubail: 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..

Consider an apartment owner in Jubail who notices a faint white crust on the basement wall, a bathroom floor that smells damp after every shower, and a hairline crack running along a balcony edge. The flat is comfortable most of the year, but the damp is slowly spreading, and the owner wants to fix it before it becomes a larger repair. Like many people in this position, the first question is not which product to use but which parts of the building actually need protection.

Jubail's location explains why this problem deserves attention. The centre of the city sits about 4 m above sea level, and it is only about 0.9 km from the sea coast. That combination means moist air and salty groundwater can reach building materials quickly, and a low-lying site can hold water after heavy rain. For an apartment owner, this points toward treating the basement, the bathrooms and the roof as priority zones, since these are the places where water most often gets in. Costs also vary by area: basement waterproofing runs from SAR 50 to SAR 150 per m², bathroom waterproofing from SAR 15 to SAR 40 per m², and epoxy coating from SAR 35 to SAR 90 per m², so measuring each zone first helps set a realistic budget.

A practical sequence starts with a walk-through. Mark every damp patch, crack and stained surface, and measure the area of each zone in square metres. Next, deal with cracks before anything else, since crack injection costs SAR 40 to SAR 120 per metre and should be finished before any coating goes on top. Then choose the surface treatment that suits each zone: a bitumen membrane or liquid roof system for the roof, bathroom waterproofing for wet rooms, and epoxy coating for floors that need a hard, washable finish. Allow each layer to cure fully before moving on, and keep a record of the work for future maintenance.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.

Tools and methods, and when we use them

How the work is done, step by step

1. Surface moisture reading: Epoxy is applied only when the substrate is dry enough.
2. Careful preparation: Grinding and cleaning for adhesion.
3. Layers: Primer and body coats as specified.
4. Inspection: Thickness and curing are checked.
