Floor & balcony waterproofing for offices & commercial complexes in Jeddah
الخلاصة: In short: In Jeddah (Jeddah), floor & balcony waterproofing for offices & commercial complexes begins with the roof, falls and drains survey and the moisture meter for ceilings and walls; nothing is opened until the position is clear. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data).
Why floor & balcony waterproofing differs in Jeddah
Team note on Jeddah: 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 Jeddah sits about 15 m above sea level (SRTM open elevation data).
Jeddah is about 2 km from the sea coast (OpenStreetMap).
Floor and balcony waterproofing for offices and commercial complexes starts with a few checks that the location itself makes necessary. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data), and the city is about 2 km from the sea coast (OpenStreetMap). Coastal air carries salt and humidity, which can speed up corrosion of embedded steel and weaken surface coatings, so the technician looks first at how water currently moves across and through the slab, and whether salt staining or rust marks are already visible at the edges of balconies and floor joints.
Some things can only be judged on site, so they are left to the visit. The technician checks whether the slab falls correctly toward drains, where ponding happens after rain, the condition of parapets and upstand edges, and whether existing tiles or screeds are bonded or hollow. Crack width and whether a crack is live or dormant are assessed by eye and by tapping the surface, not from a plan. The choice between a liquid system, a bitumen membrane, epoxy coating or spray foam depends on traffic, exposure and access, and the final decision is made once the surface has been opened up and inspected in person.
To help the technician arrive prepared, please share the building's age, the floor or balcony area in square metres, the type of finish already in place, and any history of leaks or repairs. Note whether the area is a foot-traffic corridor, a plant or service deck, or an open balcony exposed to sun and rain, since these change the system required. Indicative rate ranges for reference are liquid roof waterproofing at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², and epoxy coating at SAR 35–95 per m², with crack injection at SAR 40–125 per metre. Final pricing follows the site assessment.
For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.

- A threshold without waterproofing — we check this before anything else.
- A common cause: incorrect falls.
Tools we use in Jeddah
| Tool | What it finds | When we use it in Jeddah |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
The steps in order
- 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.

Common questions about floor & balcony waterproofing in Jeddah
Can I use household chemicals instead of calling a technician?
Using unsuitable chemicals may corrode pipes and does not fix the root cause of the blockage, so it is better to rely on a specialist technician.
What is the difference between foam insulation and other types of insulation?
Foam insulation is easy to apply on uneven surfaces and forms one continuous layer with no joints, while other types, such as bitumen rolls, need the joints to be welded. The contractor decides which is most suitable after inspecting the site.
Can thermal insulation be applied to an existing building?
Yes, thermal insulation can be installed on the roofs and walls of existing buildings without the need for major structural modifications. The contractor prepares the surface, then applies the insulating material and the protective layer over it.
What is the first step of floor & balcony waterproofing for offices & commercial complexes?
We start with checking the falls (where water collects and where it should go), then details (thresholds, drains and upstands).
