Floor & balcony waterproofing in Jeddah: for companies (annual contract)
In short: Floor & balcony waterproofing (for companies (annual contract)) 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.
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.. 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).
For companies managing floors and balconies in Jeddah, the first thing a technician checks is location, because it shapes what the surface has to withstand. 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). That closeness to the coast means salt-laden air and humidity are part of the working conditions, so the technician looks first at how water and salt have already moved through the slab, the edges of the balcony, and the junctions with walls and drainage outlets.
Some points cannot be settled from a desk and are left to the site visit. The technician walks the area to see the existing surface condition, identifies cracks and their width and direction, notes where ponding water sits after rain, and checks whether previous coatings have lifted or blistered. Access, the slope toward drains, and how the floor is used by staff or customers all affect which system fits. Because prices differ widely by method, the choice is made only after the surface has been measured on site and the work scope agreed.
To help the technician prepare, the site contact should share the floor and balcony areas, a list of any past repairs, and a note of where leaks or damp have been seen. Access times and any restrictions on noise or working hours in the building should be confirmed in advance. For reference, liquid roof waterproofing is priced at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², and epoxy coating at SAR 35–95 per m², while crack injection is priced at SAR 40–125 per m. Spray foam runs at SAR 20–45 per m², and XPS boards at SAR 15–30 per m². Having these details ready lets the technician give a clear quote that matches the building's real condition.
For companies, an annual contract sets the scope, the visit schedule and the reports in writing.

How we choose the tool in Jeddah
| 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 |
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.

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.
