What is specific about Sharurah for floor & balcony waterproofing

The centre of Sharurah sits about 724 m above sea level (SRTM open elevation data). Main roads in or near Sharurah: King Abdulaziz Road, King Fahd Road.

Team note on Sharurah: 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..

The most common problem with floors and balconies in apartments is water finding its way through cracks and worn joints at the edges, where tiles meet walls and balcony slabs meet the building. In flats, this often shows up as damp patches on the ceiling below, peeling paint near the balcony door, or tiles that sound hollow underfoot. Because the damage is usually hidden beneath finishes, it tends to grow quietly before anyone notices it.

Sharurah sits about 724 m above sea level, and that elevation shapes how we approach the work. Higher ground in this area means the surfaces are exposed to strong sun during the day and sharp temperature swings between day and night, which stress the surface and widen small cracks over time. For balconies and open terraces, this makes surface-applied systems more demanding to install and to maintain, so the approach is to prepare the substrate thoroughly and choose coatings that can handle movement. Options range from liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m², to epoxy coating at SAR 35–90 per m² where a harder, more durable finish is needed. Where a bathroom sits above a living area, bathroom waterproofing at SAR 15–40 per m² is often the more relevant line item, and crack injection at SAR 40–120 per metre can address specific cracks before any coating goes on.

Before the visit, ask the provider which system they recommend for your specific floor or balcony and why it suits an exposed, sun-heavy surface at this elevation. Ask how they will locate the source of any leak rather than only sealing the visible surface, and whether the price quoted covers surface preparation, materials and cleaning up afterwards. It also helps to ask what the work involves for neighbours below, such as protecting ceilings during the job. Having clear answers to these questions will help you compare quotes fairly and understand exactly what you are paying for.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
