Before we start: what we know about Dhahran

Team note on Dhahran: 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 centre of Dhahran sits about 16 m above sea level (SRTM open elevation data).

Dhahran is about 5.9 km from the sea coast (OpenStreetMap).

Do floors and balconies in Dhahran really need waterproofing if the weather is mostly dry? The answer depends on where the building sits. The centre of Dhahran sits about 16 m above sea level, and the city is about 5.9 km from the sea coast. Those facts mean the area is not flat ground at sea level, and it is not right on the shoreline either. Water still finds its way through small cracks and worn surfaces, and a preventive periodic check helps catch problems before they reach the rooms below.

A preventive inspection usually follows a clear order. The technician first walks the floor and balcony surfaces to look for hairline cracks, dips where water may pool, and any lifted edges around drains and railings. Crack injection is priced per metre, at SAR 40–120 per m, so measuring the length of visible cracks is one of the first steps. The inspector then checks whether the existing coating is still bonded, since spray foam costs SAR 20–45 per m² and epoxy coating costs SAR 35–90 per m², and a sound surface gives a better result before any new layer goes on. Where a balcony has a roof-like exposure, the team notes the condition of the liquid roof waterproofing, priced at SAR 8–25 per m², or the bitumen membrane at SAR 15–35 per m², depending on what is already in place. Each finding is recorded so the owner sees what is sound and what needs attention.

To prepare for the visit, gather any earlier waterproofing records, invoices, or photos that show what was applied before and when. Clear the balcony and floor areas so the inspector can reach the drains, corners, and joints without moving furniture. Note any past leaks, damp patches on ceilings below, or spots where water has stood after rain or washing. If the property has a basement, a bathroom, or a water tank, mention them in advance, because basement waterproofing is priced at SAR 50–150 per m², bathroom waterproofing at SAR 15–40 per m², and tank internal coating at SAR 25–60 per m² are separate items. Having this information ready lets the visit focus on the places that matter most.

Preventive checks follow a written schedule instead of waiting for a fault.
