Epoxy coating & waterproofing in Jubail: the local context

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

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..

Epoxy coating and waterproofing for schools in Jubail usually starts with a problem that is easy to miss until it is costly: moisture rising through floor slabs and wall bases, which lifts old paint, blisters floor finishes and leaves corridors and classrooms smelling damp. Schools also take heavy daily foot traffic and frequent cleaning with water, so worn or cracked floors let moisture in faster than a normal office. Our epoxy coating work is designed to seal these surfaces, but the first step is always to find where the water is actually getting in, not just to cover the surface.

Jubail shapes that approach in a direct way. The centre of Jubail sits about 4 m above sea level, which means ground water and salt-laden air are close to many building foundations, and Jubail is about 0.9 km from the sea coast, so coastal humidity and salt are a constant factor for exposed walls and roofs. Because of this, we look at ground-level floors and basement or semi-basement storage rooms more carefully, and we pay attention to roof edges and parapets where wind-driven salt can settle. For a school, that can mean choosing a coating system suited to a moist substrate and checking whether a membrane is needed under a new finish, rather than applying epoxy over a surface that will keep releasing moisture.

Before any visit, it helps to have a clear picture of the building. Ask which areas are showing damp, staining, cracks or lifting finishes, and whether those problems are on ground floors, roofs, bathrooms or storage spaces. Find out what the surface is made of and whether any previous coating or waterproofing has been applied. Let the team know when work can take place, since classrooms, labs and washrooms need to be cleared and kept dry during the job. You should also ask for a written scope that lists each area and the method proposed for it, so the school knows exactly what is being sealed, coated or repaired before work starts.

For schools, the larger jobs are planned for weekends and holidays.

Signs worth paying attention to

If you notice one of these signs in Jubail, it is a good moment to talk to the team:

• A tank that needs an easy-to-clean surface
• A warehouse floor that is wearing away
• Oil stains on a floor

The most common causes

• A common cause: insufficient preparation.
• A common cause: a damp surface that ruins adhesion.

Tools and methods, and when we use them

The steps in order

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.
