Floor & balcony waterproofing for apartments in Jeddah
In short: Floor & balcony waterproofing for apartments in Jeddah starts with the roof, falls and drains survey, then the moisture meter for ceilings and walls, before anything is opened. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data). Pricing starts from Bathroom waterproofing (per m²) (SAR 15–40 per m²), and other items are quoted after the visit.
Before we start: what we know about 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..

Floor and balcony waterproofing in Jeddah starts with the location itself. The centre of Jeddah sits about 15 m above sea level, and the city is about 2 km from the sea coast. Because the site is near the coast but not at sea level, a technician first looks at how water moves across the floor and balcony surfaces and where it can collect, rather than assuming that standing water will drain away on its own. Drainage outlets, floor slopes, and the lowest points of a balcony are checked early, since these are the places where a membrane or coating is most likely to be tested.
Several details are left to the site visit, because they cannot be judged from a description alone. The technician looks at the age and condition of the existing screed or tiles, any hairline cracks, and whether water is already seeping through from the unit below. Cracks are measured in metres, since crack injection is priced per metre, and the type of surface decides which system fits: spray foam, epoxy coating, liquid roof waterproofing, or a bitumen membrane. Balconies exposed to direct weather may need a different approach from enclosed bathroom floors, and the technician confirms this on the spot. The measured area in square metres is also taken at this stage, because pricing for most systems is set per m², with ranges such as SAR 10–25 per m² for liquid roof waterproofing, SAR 15–35 per m² for bitumen membrane, and SAR 35–95 per m² for epoxy coating. Actual costs depend on what the visit finds.
To help the technician prepare, it is useful to have the following ready: the approximate floor area and balcony size, the floor level of the apartment, any previous waterproofing work and its approximate date, and a note of any leaks, damp patches, or ponding after rain. Photos of cracks and the underside ceiling of the floor above, if accessible, are also helpful. Access to the balcony and the nearest drain should be arranged in advance. With this information, the technician can plan materials and the order of work before arriving, which makes the visit more efficient for the resident.
In apartment buildings, the floor below is often where a leak shows first.

Tools and methods, and when we use them
| Method | What it helps with | Its role 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 |
From the first visit to the report
- 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 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.
