Wall damp work for a school in Khobar starts with the place itself. The centre of Khobar sits about 9 m above sea level (SRTM open elevation data), and the city is about 1.8 km from the sea coast (OpenStreetMap). Because the ground is only modestly raised and the coast is close, the first thing a technician looks at is where water is coming from and how it moves through the walls, rather than assuming a single cause. Staff will want to know which walls are affected, whether the damp is rising from the floor, coming through from outside, or appearing after rain, and whether any salt deposits or crumbling plaster suggest moisture that has been present for some time.
Some of the decisions depend on what is found when the technician visits the site, so they are not settled in advance. The type of treatment, the extent of any crack repair, and whether a membrane or coating is suitable all depend on the condition of the wall, its thickness, and what lies behind it. Pricing for the common options is set out in the rate list: basement waterproofing at SAR 50–150 per m², epoxy coating at SAR 35–90 per m², spray foam at SAR 25–35 per m², crack injection at SAR 40–120 per metre, and XPS boards at SAR 10–30 per m², but the final choice and the area measured are confirmed on site. Access to classrooms, storerooms and any wet areas also needs agreeing with the school so that work can be planned around teaching hours.
To help the technician, it is useful to have a few details ready before the visit: the rooms and walls where damp has been noticed, any photos taken after rainy days, the age of the building if known, and any previous repairs or painting that may hide the true condition. Note whether the damp appears on the ground floor only or higher up, and whether any wall is partly underground, since this changes the approach. Clear notes on these points let the technician prepare the right materials and give the school an accurate picture of the work before it begins.
For schools, the larger jobs are planned for weekends and holidays.
When do you need wall damp treatment?
The following signs are worth checking before they grow:
- Peeling paint and salt marks

Tools we use in Khobar
| Method | What it helps with | Its role in Khobar |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Thermal camera | Wet areas and heat loss in the roof | Limits: needs a day–night temperature difference |
How the work is done, step by step
- Moisture readings: Readings are taken in a grid across the wall.
- Finding the cause: Pipe, condensation or rising damp.
- Treatment: The cause is treated before the finish.
- Finishing: Plaster and paint after the wall has dried.

Questions from Khobar
Can the roof be insulated over the existing insulation layer?
This depends on the condition of the old layer. If it is intact and stable, a new layer may be applied. If it is damaged, it must be removed. A technician will determine this after inspection.
What is the best type of roof waterproofing for Khobar's climate?
The choice depends on the surface and its use. Bituminous rolls and liquid polyurethane coatings are common for exposed roofs to resist heat and humidity, while cementitious materials suit tanks and bathrooms. The contractor determines the best type after inspection.
What is the best type of roof waterproofing in Al-Khobar?
It depends on the roof condition and usage. Bitumen rolls and liquid polyurethane are common, while foam with a protective layer suits those wanting both thermal and water insulation.
Where does wall damp treatment for schools start in Khobar?

Practical notes for residents of Khobar
- 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).
- 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.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
