Floor & balcony waterproofing in Dhahran: the local context

Dhahran is about 5.9 km from the sea coast (OpenStreetMap). The centre of Dhahran sits about 16 m above sea level (SRTM open elevation data).

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 most common problem with floors and balconies in Dhahran apartments is water finding its way through cracked tiles, failed joints and worn sealant at the edges where the balcony meets the wall. In a flat, water pools rather than running off, and it can seep into the slab below or into the wall of the unit underneath. Because the damage often starts hidden under finishes, many residents only notice it when paint bubbles or a ceiling stains. Waterproofing for this type of property is usually about sealing the surface and the junctions, not replacing the whole structure.

Local conditions shape how that work should be planned. The centre of Dhahran sits about 16 m above sea level, and the city is about 5.9 km from the sea coast, so a contractor should look at drainage and the fall of the balcony surface before choosing a system rather than assuming the same method suits every building. Floors and balconies here are commonly tiled, and the approach may combine a liquid or membrane layer under the finish with careful detailing at upstands and drain outlets. Where cracks are present, crack injection is priced per metre, and it is worth measuring those lengths on the day so the quote matches the real work. Ask whether the chosen system is suitable for an exposed balcony rather than an internal bathroom, because the two areas face different loads and weather.

Before the visit, ask the contractor to explain which area they will treat, how they will prepare the surface, and what finish will go on top once the waterproofing is complete. Ask for a written breakdown that shows the rate per square metre or per metre for each part of the job, so you can see where the cost comes from. Ask how long the work will take, whether the balcony can be used during curing, and who will handle any tile removal and refitting. Finally, ask to see photos of similar work on apartment floors in Dhahran, and check whether the quote includes cleaning up the site. A clear answer to these questions tells you whether the contractor understands your flat.

In apartment buildings, the floor below is often where a leak shows first.

Signs that call for floor & balcony waterproofing

The following signs are worth checking before they grow:

• A wrong fall towards the door threshold
• Water passing from the balcony to the floor below
• Damp under the light well

Where the problem usually comes from

• A common cause: incorrect falls.
• A common cause: a threshold without waterproofing.
• A blocked drain — we check this before anything else.

Tools and methods, and when we use them

The steps in order

1. Checking the falls: Where water collects and where it should go.
2. Details: Thresholds, drains and upstands.
3. Waterproofing: The layer is applied and protected.
4. Flood test: Tested before the finish goes on.
