Epoxy coating & waterproofing in Aldarb: the local context

The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data). Aldarb is about 18.7 km from the sea coast (OpenStreetMap).

Before any quote for a school job in Aldarb, the technician checks the ground and the water. The centre of Aldarb sits about 79 m above sea level (SRTM open elevation data), and the town is about 18.7 km from the sea coast (OpenStreetMap). These two facts shape how we look at moisture, because a site at this height and distance is not usually treated as a coastal salt-exposure job, but rainwater run-off and groundwater still need to be read carefully on every site. The first things we check are the substrate condition, any cracks, and where water currently collects or enters, since those decide whether the coating is applied to a slab, a basement wall, or a roof.

Some points cannot be settled from a desk and are left to the site visit. The actual slope of the roof or yard, the thickness and state of the existing screed, whether old membranes are still bonded, and the depth of any water table near basements all need to be measured on the ground. Pricing rules also depend on what is found: basement waterproofing runs from SAR 50–150 per m², bathroom waterproofing from SAR 15–40 per m², and crack injection from SAR 40–120 per metre, so the measured length of cracks and the wet area decide where in each range a job falls. Epoxy coating is priced at SAR 35–90 per m² and tank internal coating at SAR 25–60 per m², so the technician confirms which surfaces need which system before a figure is given.

For the technician, the practical notes are these. Liquid roof waterproofing sits at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², and XPS boards at SAR 12–30 per m², so each option should be compared against the access, the wet conditions and the school's timetable. Work in occupied buildings may need to be scheduled around classes, with noisy or odour-producing materials planned for holidays where possible. Record the photographs, crack lengths and wet areas on the visit sheet so the scope can be agreed with the school before any material is ordered.

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:

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

The most common causes

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

Tools we use in Aldarb

How the work is done, step by step

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.
