Bathroom waterproofing in Alula: emergency

Before we start: what we know about Alula

Main roads in or near Alula: King Abdullah Road. The centre of Alula sits about 697 m above sea level (SRTM open elevation data).

The centre of Alula sits about 697 m above sea level (SRTM open elevation data), so the first thing a technician checks in an emergency bathroom leak is not the altitude itself but what that elevation means for the building: wide temperature swings between day and night, dry air that cracks renders and sealants, and sudden desert downpours that push water toward low points. Before opening any tiles, the technician looks at where water is actually entering, whether it is rising from the floor slab, seeping through a wall joint, or dripping from the room above. Water that is only pooling on the floor is treated differently from water tracking into a neighbouring room.

What is left to the site visit is the decision on method and scope. Bathroom waterproofing in Alula is priced at SAR 15–40 per m², but the final figure depends on the area that needs treating, the substrate, and whether a crack must first be sealed with crack injection (SAR 40–120 per m). Epoxy coating (SAR 35–90 per m²), spray foam (SAR 20–45 per m²) and bitumen membrane (SAR 15–35 per m²) each suit different conditions, and the technician chooses among them only after seeing the surface. Where a leak connects to a roof or a stored-water tank, liquid roof waterproofing (SAR 8–25 per m²) or tank internal coating (SAR 25–60 per m²) may be relevant, and XPS boards (SAR 12–30 per m²) may be considered for insulation-related damp. None of these choices can be settled from a phone description alone.

To help the technician arrive prepared, note the following before the visit: which room or wall is wet, how long the damp has been visible, whether the problem is worse after showers or after rain, and whether any cracks or stained grout are already visible. Clear the floor beneath the affected area if you can, and keep the water supply to the bathroom switched off until the technician has inspected it. Photographs taken at different times of day are useful, since moisture can look very different in the morning and the evening. Clear, specific details let the technician quote accurately and bring the right materials on the first trip.

If water is flowing, close the main valve first, then call or message with photos.
