Why epoxy coating & waterproofing differs in 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..

Picture a homeowner in Riyadh who has just moved into a villa with a basement, a ground-floor bathroom and a flat concrete roof. After the first rains, a damp patch appears on a basement wall and a hairline crack shows near a floor drain. They want to know what protection makes sense, what it might cost, and whether the problem can be dealt with before it spreads. Like many owners in the city, they are weighing several options at once, and the choice depends heavily on which part of the property is affected.

The city's setting matters here. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data), which places it on a broad plateau rather than in a valley where water collects. That does not remove the need for protection, but it means the main concern is usually water reaching the structure from above and from the ground around the building, not standing flood water. For owners, this points to treating roofs, basement walls and wet rooms as separate problems, each with its own material and budget. Costs vary by surface: basement waterproofing typically falls between SAR 55–160 per m², bathroom waterproofing between SAR 15–40 per m², and liquid roof waterproofing between SAR 10–25 per m². Epoxy coating, often chosen for floors and tanks, sits between SAR 35–95 per m².

A sensible approach starts with the crack and the damp wall rather than the whole building. First, identify where water enters: note cracks, staining and where damp appears after rain. Second, deal with active cracks by crack injection, which is priced at SAR 40–125 per metre, before applying any surface system, so the coating is not undermined. Third, choose the membrane for each zone: bitumen membrane (SAR 15–35 per m²) or spray foam (SAR 20–45 per m²) for areas that need flexibility, and XPS boards (SAR 15–30 per m²) where insulation is also wanted. Fourth, coat any water tank interior separately at SAR 25–65 per m². Finally, compare written quotes that state the area measured, the materials and the surface preparation, so each figure can be checked against the work it covers.

Each job ends with a written report that carries a verification code you can check on our site.

Signs worth paying attention to

The following signs are worth checking before they grow:

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

Where the problem usually comes from

• A damp surface that ruins adhesion — we check this before anything else.
• Insufficient preparation — we check this before anything else.

Tools we use 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.
