Basement & foundation waterproofing in Khobar: with a verifiable technical report
In short: Basement & foundation waterproofing (with a verifiable technical report) in Khobar starts with the moisture meter for ceilings and walls, then the crack injection (polyurethane or epoxy), before anything is opened. The centre of Khobar sits about 9 m above sea level (SRTM open elevation data). Published price: Crack injection (per metre), SAR 40–120 per m; anything else is quoted after the inspection.

Does a basement in Khobar really need waterproofing, given that the city is not directly on the shore? The answer depends on the site. The centre of Khobar sits about 9 m above sea level (SRTM open elevation data), and the city lies about 1.8 km from the sea coast (OpenStreetMap). That combination means groundwater and moisture pressure can still reach below-grade walls and slabs, so a basement here is worth checking before any finishing work goes on. Basement waterproofing is priced at SAR 50–150 per m², and the final figure depends on the area treated, the method chosen and the condition of the existing structure.
Our inspection starts with a walk through the basement and the surrounding ground to look for damp patches, efflorescence, cracks and any signs of water entry at the joints. Technicians then measure the wet areas and mark the cracks, since crack injection is quoted per metre at SAR 40–120 per m and needs an accurate length before work begins. Where a membrane or coating is suggested, the surface is assessed for its condition and suitability, and the options are explained in plain terms: bitumen membrane at SAR 15–35 per m², epoxy coating at SAR 35–90 per m², or spray foam at SAR 25–35 per m². The inspection ends with a written summary of the areas and methods recommended, so the owner can compare choices before deciding.
To make the visit efficient, please prepare access to the basement and to any adjoining bathrooms, utility rooms or water tanks, because tank internal coating is quoted at SAR 25–60 per m² and may be relevant to the same property. Clear the walls and floor where possible so the technicians can see the full extent of any damp or cracking. Note when water was last noticed, whether it appears after rain or during dry periods, and any past repairs or previous treatments you know about. Having the property's plans or sketches to hand, along with the approximate basement dimensions, will help the team estimate the work accurately from the start.
Each job ends with a written report that carries a verification code you can check on our site.
Signs that call for basement & foundation waterproofing
The following signs are worth checking before they grow:
- Damp basement walls
- Salt marks at the bottom of the walls
- Water seeping in after rain
The most common causes
- Rainwater draining towards the foundation — we check this before anything else.
- A high groundwater level — we check this before anything else.
- Cracks at construction joints.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| 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 |
| Crack injection (polyurethane or epoxy) | Stopping active water through cracks | Limits: treats the crack, not the water source |
The steps in order
- Finding the source: Groundwater, rain or a pipe — each needs a different treatment.
- Preparation: Surfaces are cleaned and opened where needed.
- Injection: Active cracks are injected.
- Waterproofing layers: The system is applied on the right side of the wall where possible.
- Follow-up: Readings are repeated after the treatment.

Short answers for 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.

If you live in Khobar and are new to the area
- 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.
