A duplex owner in Dammam often notices the first signs of damp on the ground-floor wall that backs onto the shared stairwell or the lower unit's external face. Paint starts to bubble, a faint tide line appears above the skirting, and the plaster feels soft when pressed. The owner may live on one floor while a family rents the other, so the question of who pays and who acts can delay repairs until the stain has spread.
The local setting matters. The centre of Dammam sits about 12 m above sea level, and the city is about 4.3 km from the sea coast. That combination means moisture in the ground and in the air can still find its way into walls, especially where a building has a basement, a ground-level bathroom or an external wall that receives driving rain. Because the coast is close, salts can also travel with damp and leave white crystals on plaster. For a duplex, water rising in one unit often reaches the other, so the source is rarely confined to a single room.
Start by finding the source before choosing a treatment. Check whether the damp sits low on the wall, which points to rising moisture or a leak from below, or whether it appears near the top, which suggests a roof or parapet problem. Inspect the bathroom and kitchen pipework above and beside the affected wall. If there is a basement, note any cracks, because crack injection is priced per metre and is often the first targeted repair. Once the source is known, price the work by area: basement waterproofing ranges from SAR 50–150 per m², bathroom waterproofing from SAR 15–40 per m², and liquid roof waterproofing from SAR 10–25 per m². Agree the scope with both owners in writing, then seal the source, allow the wall to dry fully, and only then apply the finish.
In a duplex, the two floors often share lines, so tests are done floor by floor.

Questions from Dammam
How long does waterproofing take?
It depends on the area, the material type, and the surface condition. Residential roofs are usually completed within a few days, including preparation and testing.
Are the disinfectants used for sterilization safe for drinking water?
Yes, disinfectants specifically designed for drinking water tanks are used at specified concentrations, and the tank is rinsed thoroughly afterward to remove any residue. We recommend asking about the type of materials before starting.
Is it possible to carry out thermal insulation on an old roof?
Yes, it is possible after inspecting the roof, treating cracks, and removing damaged layers. The contractor determines after the site visit whether the roof needs additional preparation before the insulation is installed.
