What is specific about Aldarb for bathroom waterproofing

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

Is a bathroom in a hotel or serviced apartment in Aldarb worth waterproofing properly? Owners often ask this because guests rarely see what happens behind the tiles. Aldarb sits about 79 m above sea level, and it is roughly 18.7 km from the sea coast, so the site is inland and set well above the shoreline. Our bathroom waterproofing work here is priced per square metre, with a typical range of SAR 15–40 per m² for bathroom waterproofing. Epoxy coating runs from SAR 35–90 per m², and spray foam from SAR 20–45 per m², so the right system depends on the surfaces and how heavily the room is used.

Our inspection starts with a walk through each bathroom to check the floor, the wall junctions, the shower area and any existing cracks. We look at how water currently drains and where it has been pooling or staining. Where a crack is present, we measure its length, because crack injection is priced per metre at SAR 40–120 per m. We then record the surfaces that need treatment, note their area in square metres, and agree a scope before any work begins. Each step is written down so the owner can see exactly what is being covered and why.

Before the visit, please clear the bathrooms of loose items and make sure we can reach the shower area, the floor drain and any access panels. Tell us about any past leaks, damp patches or repairs you already know about, and let us know if the rooms are still in use during the inspection. If the property also has a basement or water tank, mention it at the outset, since basement waterproofing (SAR 50–150 per m²) and tank internal coating (SAR 25–60 per m²) are scoped separately. Having this information ready lets the inspection focus on the work that matters and gives you a clear, itemised estimate to review.

For hotels and serviced apartments, rooms are handled in batches to keep units available.
