Epoxy coating & waterproofing for residential buildings in Jeddah
In short: Epoxy coating & waterproofing for residential buildings in Jeddah starts with the moisture meter for ceilings and walls, then the thickness measurement at spread-out points, before anything is opened. Jeddah is about 2 km from the sea coast (OpenStreetMap). Published price: Epoxy coating (per m²), SAR 35–95 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).
Moisture problems in Jeddah's residential buildings most often show up as damp patches in basements, rising stains on ground-floor walls, and blistering on flat roofs and bathroom floors. In this city, the most common issue is water that enters through hairline cracks in concrete and then tracks along walls, so a surface-only coat applied without addressing the cracks tends to fail within a short period. Epoxy coating works well for floors, garages and wet areas, but it has to be bonded to sound, dry substrate, and the building's specific weak points need to be sealed first.
The local setting changes how we approach each job. The centre of Jeddah sits about 15 m above sea level, which means many plots are not as low-lying as people assume, yet the city is still only about 2 km from the sea coast, so salt-laden air and groundwater can affect masonry and steel over time. For that reason we check the substrate for salt efflorescence and moisture before choosing a system. Where cracks are active, crack injection is priced per metre at SAR 40–125 per m, and it is usually completed before any epoxy or membrane is laid. For roofs, liquid roof waterproofing at SAR 10–25 per m² or a bitumen membrane at SAR 15–35 per m² may suit the slab better than a rigid epoxy film, depending on the movement the structure experiences.
Before the visit, ask the provider which system they propose for your exact area and why, and request a written breakdown that separates crack repair, surface preparation and the coating itself. Confirm the rate per square metre or per metre for each item, so you can compare like with like: basement waterproofing runs at SAR 55–160 per m², bathroom waterproofing at SAR 15–40 per m², and epoxy coating at SAR 35–95 per m². Ask how they will check moisture before work starts, what preparation they carry out, and whether they will show you the cracked or damp areas they have identified. A clear, specific answer to these questions is a good sign that the work will be planned around your building rather than a generic package.
For a whole building, a survey of the shared systems comes before unit-by-unit work.
When do you need epoxy coating & waterproofing?
The following signs are worth checking before they grow:
- Oil stains on a floor
- A warehouse floor that is wearing away
- A tank that needs an easy-to-clean surface
Where the problem usually comes from
- A damp surface that ruins adhesion.
- Insufficient preparation.
How we choose the tool in Jeddah
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Thickness measurement at spread-out points | Whether the thickness in the quote was achieved | Limits: for foam and liquid-applied layers |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Fill test with level monitoring | Whether a tank coating holds after the work | Limits: takes time to monitor the level |
How the work is done, step by step
- Surface moisture reading: Epoxy is applied only when the substrate is dry enough.
- Careful preparation: Grinding and cleaning for adhesion.
- Layers: Primer and body coats as specified.
- Inspection: Thickness and curing are checked.

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.
Where does epoxy coating & waterproofing for residential buildings start in Jeddah?
We start with surface moisture reading (epoxy is applied only when the substrate is dry enough), then careful preparation (grinding and cleaning for adhesion).
What does epoxy coating & waterproofing cost in Jeddah?
From our published price list: Epoxy coating (per m²) SAR 35–95 per m². Quantities are confirmed at the inspection.
What do I receive after the work?
