Why epoxy coating & waterproofing differs in Taif

Team note on Taif: 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.. The centre of Taif sits about 1673 m above sea level (SRTM open elevation data).

Taif sits at the centre of the mountain belt, and the centre of the city is about 1673 m above sea level (SRTM open elevation data). That height matters for a duplex because it shapes how rain, dry heat and night-time cooling act on the building envelope. Before any quote is written, the technician checks the roof, the external walls, and any basement or ground-floor slab that touches the soil, since these are the surfaces that take the most weather and the most moisture movement. Bathrooms and the internal water tank are also checked early, because a leak there can run unseen into the structure for a long time.

Some points are left to the site visit, because they cannot be judged from a distance. The technician walks each level to find cracks, check whether a crack is active or old, and measure the true area of each surface. For cracks, the work is priced per metre, and crack injection in the range of SAR 40–115 per m depends on how long and how wide the crack is. The visit also confirms the surface condition, whether the old finish is sound or flaking, and whether a basement needs basement waterproofing at SAR 50–145 per m² or a lighter treatment. Epoxy coating, which runs SAR 35–85 per m², is only suitable where the substrate is dry and firm, so moisture readings and a surface check decide the method on the day.

The information below helps the technician prepare. Measure each surface in square metres and each crack in metres before the visit, and note which spaces are bathrooms, which are roof areas, and whether a tank is fitted. Price ranges to plan around include spray foam at SAR 25–45 per m², liquid roof waterproofing at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², tank internal coating at SAR 25–55 per m², and XPS boards at SAR 10–30 per m². Tell the technician about any past leaks, previous coatings, and access limits such as stairs or a locked roof, because these change the labour needed and the order in which work is done.

In a duplex, the two floors often share lines, so tests are done floor by floor.

Signs worth paying attention to

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

Tools we use in Taif

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.
