Before we start: what we know about Allith

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).

Main roads in or near Allith: Al Laith Road, Amr Bin Al Aas Street.

Is a floor or balcony in Allith worth waterproofing before you buy or take over a property? The centre of Allith sits about 5 m above sea level, and the town is about 1.2 km from the sea coast. That closeness to the coast means damp air and salt can work into concrete surfaces over time, so it is sensible to check the floors and balconies before you sign anything or accept the keys. Costs vary by method, so knowing what the work involves helps you plan.

An inspection for a floor or balcony should start with a walk across every surface, looking for staining, soft patches, hairline cracks and areas where paint or tiles have lifted. Cracks that run along a balcony edge or across a floor slab need a closer look, and crack injection is priced per metre, from SAR 40–120 per m, so measuring the length of visible cracks gives a useful starting figure. Where the balcony or roof is open to the sky, the inspector should note the condition of the surface and whether liquid roof waterproofing, priced at SAR 8–25 per m², or a bitumen membrane, at SAR 15–35 per m², would suit the area. Bathroom floors that sit above other living space deserve the same attention, since bathroom waterproofing ranges from SAR 15–40 per m². Each finding should be recorded with its location so the quotes you receive can be compared line by line.

Before the visit, gather the handover documents, any earlier repair records and the approximate size of each floor and balcony area in square metres. Clear the surfaces so the inspector can see the bare concrete, and note any leaks or damp patches you have already seen, with the dates if you know them. If the property has a basement or a water tank, mention these as well, because basement waterproofing costs SAR 50–150 per m² and tank internal coating costs SAR 25–60 per m², which are separate scopes of work. Having this information ready means the inspection can focus on what matters and the quotes you receive will reflect the real condition of the property.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.
