Epoxy coating & waterproofing in Alkharj: the local context

Team note on Alkharj: 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 Alkharj sits about 439 m above sea level (SRTM open elevation data).

Before any work starts on a school in Alkharj, the first thing checked is the ground the building sits on. The centre of Alkharj sits about 439 m above sea level (SRTM open elevation data), and that height shapes how water moves across a site, where it collects, and which surfaces take the most exposure. Because schools often have large flat roofs, long corridors and ground-level floors that see heavy foot traffic, the technician records which areas are most likely to hold water or wear quickly. Pricing is then discussed against the scope, using the published ranges: epoxy coating at SAR 35–90 per m², crack injection at SAR 40–120 per metre, and liquid roof waterproofing at SAR 8–25 per m². These ranges give a starting point, but the final figure depends on what the visit reveals.

The site visit settles the details that cannot be judged from a drawing. The technician walks the floors, checks the state of existing surfaces, measures the true area of each space, and looks for cracks, damp patches and old failed membranes. Decisions such as whether a basement needs full waterproofing at SAR 50–150 per m², whether bathrooms need the lighter treatment at SAR 15–40 per m², or whether a water tank needs an internal coating at SAR 25–60 per m², are made on site rather than from the office. The choice between spray foam at SAR 20–45 per m², a bitumen membrane at SAR 15–35 per m², or XPS boards at SAR 12–30 per m² also depends on access, the condition of the substrate and how long the school can keep areas closed.

To help the technician prepare, the school should provide a plan of the buildings, a list of rooms that will be in use during works, access times that suit the timetable, and any records of past repairs. Tell us where leaks have appeared, when they occur, and whether they follow rain or cleaning routines. Clear access to roofs, basements and tank rooms saves time on the visit. With this information the team can match the right system to each area, confirm the scope in writing, and plan the work so that classes can continue with as little disruption as possible.

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

Signs that call for epoxy coating & waterproofing

These are the signs most often linked to epoxy coating & waterproofing:

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

Causes we see in the field

• Insufficient preparation.
• A damp surface that ruins adhesion.

Tools and methods, and when we use them

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.
