Floor & balcony waterproofing in Almajmaah: the local context

Team note on Almajmaah: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. Main roads in or near Almajmaah: King Abdullah Road, King Fahd Road, King Salman Road.

The centre of Almajmaah sits about 720 m above sea level (SRTM open elevation data).

The most common problem with floors and balconies in Almajmaah is water finding its way through cracked tiles, failed grout and worn joints at the edges where the balcony meets the wall. Because the centre of Almajmaah sits about 720 m above sea level, the air is often dry for long stretches, so homeowners may not notice damage until a rain shower or a heavy wash reveals a damp patch on the ceiling below. Waiting until the stain appears usually means the water has already travelled through the slab, so it is worth looking for early signs such as hairline cracks, loose tiles that sound hollow when tapped, or paint that bubbles near the floor edge.

The altitude shapes how we approach the job. At around 720 m, the sun is strong and the temperature swings between day and night can be sharp, which stresses surface coatings and makes them expand and contract. For this reason the approach favours flexible systems over rigid ones, and the surface must be fully dry before any new layer goes on. A crack that appears in a balcony floor is usually treated with crack injection, priced at SAR 40–120 per metre, before the main coating is applied. For a large open balcony, a liquid membrane or a bitumen layer, at SAR 15–35 per m², can give a continuous seal that moves with the surface. Where the balcony is covered by a roof above, liquid roof waterproofing at SAR 8–25 per m² is often the more economical choice.

Before the visit, ask the technician to measure the exact area in square metres and to check for cracks in metres, so the quote can be compared against the ranges above. Ask which system is proposed and why, and whether the surface will be cleaned and dried before application. Find out how long the old tiles or grout will be removed and whether the balcony will be usable during the work. Request that the scope be written down, including the materials and the area covered, so you can check the finished job against what was agreed.

Some signs can be watched for a few days; others need a technician straight away — the signs list above helps you decide.
