Before we start: what we know about Dhahran

Team note on Dhahran: 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.. Dhahran is about 5.9 km from the sea coast (OpenStreetMap).

The centre of Dhahran sits about 16 m above sea level (SRTM open elevation data).

Is epoxy coating or waterproofing worth it for a school building in Dhahran, given how close the city sits to the coast? The short answer is that the location gives good reason to plan carefully. The centre of Dhahran sits about 16 m above sea level, and the city is about 5.9 km from the sea coast. Those facts mean a school's floors, walls and water tanks are exposed to a mix of ground conditions and humid air that a site further inland might not face, so the right coating depends on which surface needs protection. Epoxy coating for school floors and wet areas typically falls in the range of SAR 35–90 per m², while basement waterproofing runs SAR 50–150 per m², bathroom waterproofing SAR 15–40 per m², and tank internal coating SAR 25–60 per m².

Before any work is quoted, the site is inspected in clear steps. The inspector walks the building and checks each surface type separately, noting floors, bathrooms, roof areas, basement walls and any water tanks. Cracks are recorded and measured, since crack injection is priced per metre at SAR 40–120 per m, and the inspector marks where moisture is coming through. The roof is assessed for liquid roof waterproofing at SAR 8–25 per m² or bitumen membrane at SAR 15–35 per m², and insulation options such as XPS boards at SAR 12–30 per m² or spray foam at SAR 20–45 per m² are discussed where they suit the structure. The findings are then written up area by area so the school can compare the options on the same basis.

To make the visit productive, the school should prepare a few things in advance. Gather any existing drawings or plans that show the floor areas, roof layout and basement extent, because accurate square metre figures are what the price ranges are built on. List the areas where leaks or damp have already been noticed, with approximate dates, and note any rooms that are regularly in use so that work can be scheduled around the timetable. Clear access to the roof, basement, bathrooms and water tanks will save time on the day. Having these details ready lets the inspection focus on the real problems instead of searching for them.

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

Signs that call for epoxy coating & waterproofing

These are the signs most often linked to epoxy coating & waterproofing:

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

The most common causes

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

Tools and methods, and when we use them

From the first visit to the report

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.
