Before we start: what we know about Riyadh

Main roads in or near Riyadh: King Fahd Road, King Abdullah Road, King Abdullah. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data).

Team note on Riyadh: 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..

Is epoxy coating or waterproofing worth it for a school in Riyadh, and what will it cost? The centre of Riyadh sits about 637 m above sea level, and schools here face their own mix of heat, dust and water-related wear across floors, washrooms and stored water tanks. Epoxy coating on school floors and tank interiors typically runs SAR 35–95 per m², while tank internal coating is priced separately at SAR 25–65 per m². For washrooms, bathroom waterproofing is quoted at SAR 15–40 per m², and basements or lower floors at SAR 55–160 per m². These ranges give a property owner a clear starting point before any site visit.

Once a request is booked, the inspection walks through the building in a fixed order. The technician first checks the areas where water is most likely to collect, such as washrooms, roof surfaces and any basement or ground-level rooms. Cracks are measured in metres, because crack injection is charged at SAR 40–125 per metre, so the length found on site drives the scope. The team then notes the surface type and the area in square metres for each zone, so the coating method can be matched to the material beneath. Where a roof is involved, liquid roof waterproofing at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m² or spray foam at SAR 20–45 per m² may be discussed as options, and XPS boards at SAR 15–30 per m² may be considered where insulation is also needed.

To make the visit productive, the property owner should prepare a simple plan of the school with each floor, washroom, basement and tank marked. It helps to list any known leaks, damp patches or cracks, and to note when they first appeared. Access should be arranged in advance for roof areas, plant rooms and tank locations, and the timing should avoid school hours where possible so that classrooms and washrooms can be cleared. Having the approximate square metres of each area ready allows the inspection to produce a clear estimate that matches the price ranges above.

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

When do you need epoxy coating & waterproofing?

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

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

Causes we see in the field

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

How we choose the tool in Riyadh

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.
