Before we start: what we know about Sabya

Main roads in or near Sabya: King Fahd Road, King Abdulaziz Road, King Abdullah bin Abdulaziz Road. Team note on Sabya: 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..

Sabya is about 16.7 km from the sea coast (OpenStreetMap). The centre of Sabya sits about 40 m above sea level (SRTM open elevation data).

Is a balcony or floor leak in a villa in Sabya something you can wait out? Usually it is not, and the sooner it is looked at, the less damage it tends to cause. Sabya sits about 40 m above sea level, and the centre of town is about 16.7 km from the sea coast. That means the area is inland and well above the coastline, so you are not dealing with the same standing-water situation you might find in low-lying coastal districts. Moisture still finds its way through slabs, joints and balcony edges, though, and the right fix depends on where it enters. Our waterproofing work for floors and balconies covers liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², and crack injection at SAR 40–120 per metre, with other options such as epoxy coating at SAR 35–90 per m² and spray foam at SAR 20–45 per m² where the surface calls for them.

The inspection starts with a walk over the floor, balcony and any roof area to find where water is getting in and how far it has travelled. The technician notes cracks, lifted tiles, blocked drainage points and stains on ceilings below, and measures the areas that will need treatment so the price can be worked out per square metre or per metre of crack. Where a balcony or terrace has a history of ponding or damp patches, the surface is checked for slope and for the condition of the existing membrane before any recommendation is made. The findings are explained on site, and you are shown which parts are urgent and which can be planned later, so you can decide what to do first.

To make the visit useful, clear the balcony and floor area of furniture, plants and loose items so the technician can reach the edges and joints. Note when you first saw the leak, whether it gets worse after rain, and which room or ceiling is affected, since this helps locate the source. Have any previous waterproofing records or contractor invoices ready, along with access to the roof and the room below. If there are cracks you have already noticed, mark them with tape so they are easy to find. With these details in hand, the inspection can move straight to finding the cause and agreeing on a sensible plan for your villa.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.
