Why floor & balcony waterproofing differs in Aldarb

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 material is chosen for a clinic floor or balcony in Aldarb, the first check is the site's position relative to the coast and the terrain. The centre of Aldarb sits about 79 m above sea level, and the town is about 18.7 km from the sea coast. Because of this inland, elevated setting, the technician should look first at how water drains off the surfaces and whether it pools in low corners, drain outlets and junctions with walls. Clinics also see frequent wet cleaning and sterilisation routines, so the join between floor and wall, and the edges of any balcony slab, need particular attention before the work is priced or scheduled.

Several things cannot be judged from a desk and are left to the site visit. The technician must confirm the actual condition of the substrate, whether there are active cracks, and whether any old membrane is lifting or has already failed. Slope, screed thickness, the state of existing drains and the presence of moisture rising from below all need to be measured on the spot. The visit should also record access constraints inside a working clinic, such as patient flow, hours when rooms can be closed, and whether the balcony is above occupied space. Only after these conditions are confirmed can the right system, whether liquid roof coating, bitumen membrane, epoxy or spray foam, be matched to the surface.

For the technician's own planning, the reference rates below help frame the scope of work and are quoted per square metre unless stated otherwise: liquid roof waterproofing SAR 8–25 per m², bitumen membrane SAR 15–35 per m², spray foam SAR 20–45 per m², and epoxy coating SAR 35–90 per m². Crack injection is charged SAR 40–120 per metre, so any cracks found at the visit should be measured and noted separately. Bathroom waterproofing runs SAR 15–40 per m², and XPS boards SAR 12–30 per m² where insulation is also needed. Recording the exact areas, crack lengths and drainage points during the visit will let the final quotation follow directly from these figures.

For clinics, work is scheduled around patient hours and kept to the areas that need it.
