Epoxy coating & waterproofing in Jeddah: preventive periodic check
الخلاصة: In short: In Jeddah (Jeddah), epoxy coating & waterproofing (preventive periodic check) begins with the moisture meter for ceilings and walls and the thickness measurement at spread-out points; nothing is opened until the position is clear. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data).
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.. 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).
Start a preventive periodic check in Jeddah with the location itself, because it shapes what fails first. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data), yet the city is still close to the water, and Jeddah is about 2 km from the sea coast (OpenStreetMap). That mix of salt-laden air and a short distance to the shore means the technician looks first at surfaces that face the weather and at any epoxy or sealed finish that has started to chalk, lift or discolour. Salt and humidity work into joints and edges long before a leak appears on the inside, so the first pass is a visual and tactile check of coatings on exposed floors, walls and tank surfaces.
Several things cannot be judged from a description and are left to the site visit. The technician needs to see whether a basement wall is damp, whether a bathroom floor has softened under the tiles, whether a roof membrane has blistered after heat, and how far a crack runs and whether it moves. Access, substrate condition and the moisture level at the time of the visit decide whether epoxy coating, spray foam, crack injection or a liquid roof system is the right repair, and the work is priced by area or length only after that assessment. The same applies to whether a bitumen membrane or XPS boards suit a particular build. None of this can be settled from an office, so the check ends with the technician's own notes and photographs.
To help the technician arrive prepared, the resident or manager should note when the problem was first seen, whether it worsens after rain or in the afternoon heat, and which rooms or tanks are affected. Clear access to the basement, roof and any water tank, and a rough measure of the affected area or crack length, saves time on the day. Indicative ranges already in use include epoxy coating at SAR 35–95 per m², basement waterproofing at SAR 55–160 per m², crack injection at SAR 40–125 per metre and tank internal coating at SAR 25–65 per m², but the final figure follows the inspection, not the other way round.
Preventive checks follow a written schedule instead of waiting for a fault.
Signs that call for epoxy coating & waterproofing
If you notice one of these signs in Jeddah, it is a good moment to talk to the team:
- Oil stains on a floor
- A tank that needs an easy-to-clean surface
- A warehouse floor that is wearing away
Where the problem usually comes from
- Insufficient preparation — we check this before anything else.
- A damp surface that ruins adhesion.
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 |
| Thickness measurement at spread-out points | Whether the thickness in the quote was achieved | Limits: for foam and liquid-applied layers |
| Fill test with level monitoring | Whether a tank coating holds after the work | Limits: takes time to monitor the level |
The steps in order
- 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.
What is the first step of epoxy coating & waterproofing (preventive periodic check)?
We start with surface moisture reading (epoxy is applied only when the substrate is dry enough), then careful preparation (grinding and cleaning for adhesion).
How much 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 get at the end?
The epoxy system, thickness and curing time, in a technical report that carries a verification code.
What we advise against
- Coating over a damp surface
The written outputs
The written output: the epoxy system, thickness and curing time. The report is numbered and can be checked with its verification code.
Planning the visit in Jeddah
- You can message us on WhatsApp in English; the booking details are sent back to you in the chat to confirm before the visit.
- The Saudi weekend is Friday and Saturday; mention your preferred day and time when booking.
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
