Floor & balcony waterproofing in Khobar: the local context
Team note on Khobar: 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.. Khobar is about 1.8 km from the sea coast (OpenStreetMap).
The centre of Khobar sits about 9 m above sea level (SRTM open elevation data).
Before any material is chosen for a floor or balcony in Khobar, the first thing checked is the site's position on the map. The centre of Khobar sits about 9 m above sea level, and the city is about 1.8 km from the sea coast. Those two facts mean the ground is low and close enough to the coast that salt-laden air and shallow moisture can reach the slab, so the technician looks first at where water could collect and at the drainage path toward the balcony edge or floor outlet. Because the coast is near, the check also covers salt staining and efflorescence on the surface, since these point to moisture moving up through the concrete.
Some things can only be judged on site and are left to the visit. The technician walks the floor and balcony to find low spots, ponding, cracks, and any old membrane that has lifted or split. They check the slope to drains, the condition of the upstand at walls, the state of the tiles or screed above the waterproofing, and whether the surface is sound enough to bond a new layer. Prices in the range of SAR 10–25 per m² for liquid roof waterproofing or SAR 15–35 per m² for a bitumen membrane are only a starting point, since the real choice depends on what the site shows. A crack that needs injection, priced at SAR 40–120 per metre, can only be sized once it has been seen up close.
To help the technician, it is useful to share the age of the building, any previous leaks or repairs, which rooms sit directly below the balcony or floor, and whether the surface is accessible while the work is done. Photos of stains on the ceiling below and notes on when water appears after rain are also helpful. Knowing whether the area is an exposed roof, a balcony with tiles, or a floor under a bathroom lets the technician pick the right system, from epoxy coating at SAR 35–90 per m² to spray foam at SAR 20–45 per m². Clear details at the start make the site visit shorter and the quote more accurate.
In apartment buildings, the floor below is often where a leak shows first.

Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
How the work is done, step by step
- Checking the falls: Where water collects and where it should go.
- Details: Thresholds, drains and upstands.
- Waterproofing: The layer is applied and protected.
- Flood test: Tested before the finish goes on.

Questions from Khobar
Can the roof be insulated over the existing insulation layer?
This depends on the condition of the old layer. If it is intact and stable, a new layer may be applied. If it is damaged, it must be removed. A technician will determine this after inspection.
What is the best type of roof waterproofing for Khobar's climate?
The choice depends on the surface and its use. Bituminous rolls and liquid polyurethane coatings are common for exposed roofs to resist heat and humidity, while cementitious materials suit tanks and bathrooms. The contractor determines the best type after inspection.
What is the best type of roof waterproofing in Al-Khobar?
It depends on the roof condition and usage. Bitumen rolls and liquid polyurethane are common, while foam with a protective layer suits those wanting both thermal and water insulation.
