Does an office or commercial bathroom in Aljumum really need waterproofing, and what will it cost? The centre of Aljumum sits about 200 m above sea level, and bathroom waterproofing for offices and commercial complexes is typically priced at SAR 15–40 per m². That range gives a property owner a starting point, though the final figure depends on the floor area, the condition of the existing surface and the system chosen. Bathrooms in busy commercial buildings take constant water use, so a sealed floor and wall layer protects the slab below and the offices underneath from leaks and damp.
Before any work starts, the inspection looks at the bathroom as a whole. The technician checks floor falls toward drains, examines wall junctions and pipe penetrations, and looks for cracks or hollow tiles that let water travel into the structure. Where a crack is found, crack injection is priced at SAR 40–120 per metre, and that repair is usually done before the membrane goes on. Surfaces are then assessed for moisture and cleanliness, since coatings bond poorly to dust, old sealant or standing damp. The inspector notes which options suit the space: epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², or a bitumen membrane at SAR 15–35 per m². Each option is matched to traffic, exposure and budget rather than offered as a single standard solution.
To make the visit efficient, gather the building's floor plans and any previous waterproofing records, and note the bathroom areas that leak or stain. Arrange access to the rooms below so the inspector can check ceilings for water damage. Clear the bathroom of fixtures where possible, and tell the team when the space is in use so work can be scheduled around occupants. Having these details ready lets the inspection move directly to measuring, testing and a clear written quotation.
For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.
