Floor & balcony waterproofing in Jeddah: cost & published offers
In short: Floor & balcony waterproofing (cost & published offers) in Jeddah starts with the roof, falls and drains survey, then the moisture meter for ceilings and walls, before anything is opened. Jeddah is about 2 km from the sea coast (OpenStreetMap). Published price: Bathroom waterproofing (per m²), SAR 15–40 per m²; anything else is quoted after the inspection.
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.. Jeddah is about 2 km from the sea coast (OpenStreetMap).
The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data).
An owner of a flat with a rooftop-style balcony in Jeddah often notices a damp patch on the ceiling below after a heavy rain, or a stain spreading along a wall where the balcony meets the building. The owner may not know whether the fault is in the floor surface, the drainage outlets, or the joints around the edge, and may want to compare a few quotes before committing any money.
The location matters here. The centre of Jeddah sits about 15 m above sea level, and the city is about 2 km from the sea coast. Being close to the coast means salt-laden air and humidity can accelerate wear on sealants and exposed concrete, so surfaces that were sound at handover can start to fail sooner than owners expect. Because the land is only slightly elevated, rainwater does not always run away quickly, so standing water on a poorly sloped balcony can sit long enough to find its way into hairline cracks. For an owner, this means the first job is to find out where the water is actually entering, rather than simply repainting the underside of the slab.
Start by inspecting the balcony after rain, noting where water pools, where the tiles or screed are cracked, and where the balcony meets the wall. Next, have a contractor check whether any crack needs crack injection, which is priced per metre, so measuring the total length of visible cracks helps you compare quotes fairly. Then decide on the surface system: liquid roof waterproofing per m² is often used on exposed balcony floors, while a bitumen membrane or XPS boards can be considered where a more robust layer is needed beneath tiles. Ask each provider to quote per square metre and to state exactly which materials and layers are included. Finally, request a written scope, confirm the drainage outlets are cleared, and agree on how the work will be checked before the balcony is returned to use.
Prices shown on this page come from our own published price list for the city; the final price is set after inspection.

Tools and methods, and when we use them
| Method | What it helps with | Its role in Jeddah |
|---|---|---|
| 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 |
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.

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.
