What is specific about Allith for epoxy coating & waterproofing

Main roads in or near Allith: Al Laith Road, Amr Bin Al Aas Street. Allith is about 1.2 km from the sea coast (OpenStreetMap).

The centre of Allith sits about 5 m above sea level (SRTM open elevation data).

Do duplexes in Allith really need epoxy coating or waterproofing, and how do you know which one your home needs? The answer starts with location. The centre of Allith sits about 5 m above sea level (SRTM open elevation data), and the town is about 1.2 km from the sea coast (OpenStreetMap). That closeness to the coast means moist air and salt can reach walls, floors and foundations, so a duplex here can benefit from a protective layer on exposed surfaces. Epoxy coating typically falls in the range of SAR 35–90 per m², while spray foam is listed at SAR 20–45 per m², and both are options worth discussing for suitable areas. Basement waterproofing is priced at SAR 50–150 per m², bathroom waterproofing at SAR 15–40 per m², and crack injection at SAR 40–120 per metre, so the right choice depends on where the problem actually is.

Our visit to a duplex in Allith begins with a walk-through of the building to identify where moisture, cracking or staining appears. The inspector looks at the basement or ground floor first, then bathrooms, balconies and roof areas, noting any cracks and checking how water moves across each surface. Cracks are measured in metres so the team can estimate crack injection work, and wet areas are marked so the team can compare options such as liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², or XPS boards at SAR 12–30 per m² where insulation is also a concern. Tank internal coating, at SAR 25–60 per m², is assessed separately if a water tank is part of the property. After the inspection, the team explains the recommended options in plain terms so you can decide what to do and in what order.

Before the visit, gather a few details that make the inspection faster and more accurate. Note where you have seen damp patches, peeling paint or water entering, and when the problem is worst, such as after rain or during humid months. Have any previous repair records or photos ready, and make sure someone can open the basement, roof access and bathrooms. Clear space around walls and floors so the team can move freely and check the surfaces properly. Tell us which parts of the duplex you use most, since that will help shape the plan. With this information ready, your inspection can focus on the problem areas and give you a clear picture of what the work will involve.

In a duplex, the two floors often share lines, so tests are done floor by floor.

Signs worth paying attention to
