Basement & foundation waterproofing in Khobar: for companies (annual contract)
الخلاصة: In short: In Khobar (Khobar), basement & foundation waterproofing (for companies (annual contract)) begins with the moisture meter for ceilings and walls and the crack injection (polyurethane or epoxy); nothing is opened until the position is clear. The centre of Khobar sits about 9 m above sea level (SRTM open elevation data).
Why basement & foundation waterproofing differs in Khobar
The centre of Khobar sits about 9 m above sea level (SRTM open elevation data). Khobar is about 1.8 km from the sea coast (OpenStreetMap).

Khobar sits about 9 m above sea level, and its centre is roughly 1.8 km from the coast. That combination matters for basements and foundations. Being this close to the sea means salt-laden air and a high water table in many districts, so groundwater pressure and salt exposure can work against concrete over time. At 9 m above sea level the ground is low and flat, so surface water has fewer natural routes to drain away, and rainwater can pool against foundation walls if the external grading is poor. For companies with ground-floor storage, server rooms or underground parking, these conditions make early attention to waterproofing far less costly than repairs after water has entered.
Each of these site facts translates into a practical choice. Because the water table and salt exposure are a concern, we start with a survey of the wall and slab condition and the likely water path, then match the system to it. Basement waterproofing is priced at SAR 50–150 per m², and the final figure depends on the membrane selected and the depth of work needed. Where water is already seeping through cracks, crack injection at SAR 40–120 per m is usually the first step, because sealing the cracks before applying a surface system prevents the water from simply finding another route. For tanks and water-holding basins, tank internal coating at SAR 25–60 per m² protects against both leakage and the chemical effects of stored water. Epoxy coating at SAR 35–90 per m² suits floors that carry traffic or equipment, and spray foam at SAR 25–35 per m² offers a quick option for certain wall and roof areas. Liquid roof waterproofing at SAR 10–25 per m² and bitumen membrane at SAR 15–35 per m² cover roof and podium areas, while XPS boards at SAR 10–30 per m² can add insulation and drainage behaviour to external walls.
Owners who manage these projects well tend to avoid a few common mistakes. They do not treat a cracked wall as cosmetic, because a surface coating over an active crack will fail quickly. They do not choose the cheapest per-square-metre rate without checking whether surface preparation, priming and crack treatment are included. They do not ignore drainage outside the building, since at this elevation a waterproof membrane cannot compensate for water that is left sitting against the foundation. Finally, they do not delay repairs after the first sign of damp, as small leaks in a basement or on a flat roof usually grow more expensive with each rainy season.
For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
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
Where the problem usually comes from
- Rainwater draining towards the foundation.
- A common cause: a high groundwater level.
- 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 |
From the first visit to the report
- 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.

Common questions about basement & foundation waterproofing in 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.
What is the first step of basement & foundation waterproofing (for companies (annual contract))?
We start with finding the source (groundwater, rain or a pipe — each needs a different treatment), then preparation (surfaces are cleaned and opened where needed).
How much does basement & foundation waterproofing cost in Khobar?
From our published price list: Crack injection (per metre) SAR 40–120 per m; Basement waterproofing (per m²) SAR 50–150 per m². Quantities are confirmed at the inspection.
What do I get at the end?

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.
