Why epoxy coating & waterproofing differs in Makkah

Team note on Makkah: 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 Makkah sits about 301 m above sea level (SRTM open elevation data).

The first thing checked on a school job in Makkah is the ground the building sits on, because the centre of the city lies about 301 m above sea level according to SRTM open elevation data. That height matters for how rain drains off roofs, courtyards and car parks, and it shapes where water is likely to pool or find its way toward walls and floors. Before any product is chosen, the technician looks at the fall of the surfaces around the school, the outlets for roof water, and any low corners where moisture could sit. Quoted rates are a useful starting point for planning: epoxy coating runs SAR 35–95 per m², basement waterproofing SAR 55–160 per m², and crack injection SAR 40–125 per metre. Where a school has a basement or a lower storey partly below ground, that area is treated with more care than an open roof.

Several things are left to the site visit, because they cannot be judged from a plan. The actual condition of each surface has to be seen in person: whether the existing coating is lifting, where cracks run and how wide they are, whether old bitumen membrane is still sound, and how the bathroom floors and their falls behave under use. The technician also needs to confirm which areas are wet every day and which only see occasional water, since that decides between spray foam at SAR 20–45 per m², liquid roof waterproofing at SAR 10–25 per m², and XPS boards at SAR 15–30 per m². Water tanks on the roof or in the grounds should be opened and inspected, because tank internal coating at SAR 25–65 per m² depends on the state of the old lining and the concrete beneath it. Access, the hours the school can be closed, and the safe routes for materials are also settled on site.

To help the technician arrive prepared, it is useful to have the school's drawings, a list of the areas that flood or leak, dates of earlier repairs, and any notes on which surfaces students and staff use most. A clear map of roof drains, tank locations and basement access saves time. Keep the work zones separate from classrooms where possible, and agree on quiet hours for noisy stages such as grinding or injection. With these details gathered in advance, the site visit can focus on confirming the scope rather than discovering it, and the chosen system can be matched to each part of the building with fewer surprises.

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

Signs worth paying attention to

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

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

Causes we see in the field

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

Tools and methods, and when we use them

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.
