What is specific about Afif for epoxy coating & waterproofing

Team note on Afif: 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 Afif sits about 1040 m above sea level (SRTM open elevation data).

Main roads in or near Afif: King Abdulaziz Road, King Faisal Road, Airport Road.

Afif sits in the high country of Najd, and the centre of the town lies about 1040 m above sea level (SRTM open elevation data). That altitude means villas here face a different climate from the coastal cities. Days can be hot and dry, while nights and winter weather can turn cold, and the sudden shifts in temperature put stress on concrete, render and roof finishes. For owners, the practical effect is that surfaces expand and contract more than they would at lower, steadier levels, so coatings need to be flexible enough to move with the building rather than crack when it does.

Because of this, the scope of work usually follows the part of the villa that takes the most punishment. Basement waterproofing typically falls between SAR 50–150 per m², bathroom waterproofing between SAR 15–40 per m², and epoxy coating between SAR 35–90 per m². Liquid roof waterproofing, at SAR 8–25 per m², is often the most economical way to protect a flat roof, while spray foam at SAR 20–45 per m² and bitumen membrane at SAR 15–35 per m² are other options depending on the substrate. Crack injection, priced at SAR 40–120 per metre, is the right first step wherever a crack is still active, because sealing it before a coating goes on prevents the same line from reappearing through the new surface. Tank internal coating at SAR 25–60 per m² and XPS boards at SAR 12–30 per m² round out the choices for water storage and insulation work.

Owners in Afif tend to avoid a few predictable errors. They do not apply epoxy over damp or dusty concrete, because adhesion fails when moisture is trapped beneath the film. They do not skip crack injection and hope a coating will bridge a moving joint. They do not choose the cheapest per-square-metre rate without checking the surface preparation included, since preparation is what decides how long the work lasts. And they do not leave roofs and basements to the last moment, when water entry has already damaged finishes inside the home. Planning these jobs around the local climate and the actual condition of each surface is what keeps a villa dry for years.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.

Signs that call for epoxy coating & waterproofing

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

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

The most common causes

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

How we choose the tool in Afif

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.
