Epoxy coating & waterproofing for schools in Jeddah
In short: In Jeddah (Jeddah), epoxy coating & waterproofing for schools 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). Published price: Epoxy coating (per m²), SAR 35–95 per m²; anything else is quoted after the inspection.
Why epoxy coating & waterproofing differs in Jeddah
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).

Will a school floor or wall in Jeddah really need waterproofing, given that the city is close to the sea? Jeddah sits about 2 km from the sea coast, and its centre is about 15 m above sea level according to SRTM open elevation data. Those are the two facts that shape how property owners here think about moisture, salt and water movement around school buildings. Coastal air carries salt and humidity, and the relatively low elevation means site drainage needs attention. For schools, the practical question is which surfaces take the most wear and where water is most likely to get in, such as basements, bathrooms, roofs and water tanks.
Our inspection starts with a walk through the building to note the surfaces involved. We check basement walls and floors, bathroom floors and wall bases, roof areas, and any tanks on site. Visible cracks are measured in metres and recorded, since crack injection is priced per metre and is often needed before a coating can bond properly. Each surface is then matched to a suitable system: epoxy coating, spray foam, liquid roof waterproofing, bitumen membrane, tank internal coating or XPS boards. The inspector notes the approximate area in square metres for each system, so the owner can compare options. Indicative ranges for these systems run from SAR 10 to SAR 160 per m², depending on the surface and the work involved, and the final figure follows the site survey.
Before the visit, please gather the building plans if you have them, and show the inspector where the basement, bathrooms, roof and tanks are located. Note any areas where you have seen damp patches, peeling paint or water stains, and say when they first appeared. Clear access to the roof, basement and tank spaces saves time on the day. If the school is still in use, let us know which rooms can be worked in and at which hours, so classes are disturbed as little as possible. A written list of your priorities will help us recommend the right coating and plan the work around the school calendar.
For schools, the larger jobs are planned for weekends and holidays.
Signs worth paying attention to
If you notice one of these signs in Jeddah, it is a good moment to talk to the team:
- A tank that needs an easy-to-clean surface
- A warehouse floor that is wearing away
- Oil stains on a floor
Causes we see in the field
- Insufficient preparation — we check this before anything else.
- A damp surface that ruins adhesion — we check this before anything else.
How we choose the tool in Jeddah
| Tool | What it finds | When we use it in Jeddah |
|---|---|---|
| Fill test with level monitoring | Whether a tank coating holds after the work | Limits: takes time to monitor the level |
| 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 |
From the first visit to the report
- 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.

Common questions about epoxy coating & 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.
What is the first step of epoxy coating & waterproofing for schools?
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.

The written outputs
You receive: the epoxy system, thickness and curing time, in a technical report with a verification code.
If you live in Jeddah and are new to the area
- 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).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
