Epoxy coating & waterproofing in Riyadh: preventive periodic check

Why epoxy coating & waterproofing differs in Riyadh

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.. 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).

The most common problem we see in Riyadh homes and small commercial units with epoxy coating and waterproofing work is not a sudden failure but slow deterioration that goes unnoticed until water appears in the wrong place. Floors in garages, store rooms and basements lose their seal at joints and edges first, and bathrooms show it around drains and skirting. A periodic preventive check catches these early, when the repair is a small patch rather than a rebuild. Prices vary by surface and scope: basement waterproofing typically falls between SAR 55 and SAR 160 per m², bathroom waterproofing between SAR 15 and SAR 40 per m², and epoxy coating between SAR 35 and SAR 95 per m².

Local conditions change how the check is approached. The centre of Riyadh sits about 637 m above sea level, which means the site is an inland plateau rather than a coastal area, and the technician should plan the inspection around the heat and dust that define the local climate. Surfaces here are exposed to strong sun, large daily temperature swings and fine airborne dust that can settle into coating films and reduce adhesion. For this reason the check looks closely at roof and terrace surfaces, where liquid roof waterproofing is commonly priced between SAR 10 and SAR 25 per m², and at any hairline cracks, which may be repaired by crack injection at SAR 40 to SAR 125 per metre. Where a water tank is part of the property, tank internal coating, priced between SAR 25 and SAR 65 per m², is checked along with the other surfaces.

Before the visit, ask the provider to confirm which surfaces will be inspected and whether the quote is per square metre or per metre of crack. Ask which materials they would recommend for your area, such as spray foam at SAR 20 to SAR 45 per m² or bitumen membrane at SAR 15 to SAR 35 per m², and why. Ask whether XPS boards at SAR 15 to SAR 30 per m² are suggested for any insulated surfaces, and how the check report will describe the condition of each area. A clear written scope before the visit makes the preventive check easier to compare and to act on afterwards.

Preventive checks follow a written schedule instead of waiting for a fault.

When do you need epoxy coating & waterproofing?

The following signs are worth checking before they grow:

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

Where the problem usually comes from

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

Tools we use in Riyadh

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.
