Picture the owner of a small office building or commercial unit in Alkharj who has noticed a damp patch spreading along the lower wall of the basement store room. Staff have started moving files off the floor, a faint smell hangs in the air after rain, and the owner wants to fix the problem before it reaches the tenants upstairs. Like many owners of this property type, they are not sure whether the water is coming from the ground, a cracked wall, or the drainage around the building, and they want a clear plan rather than a quick patch.
The local facts matter here. The centre of Alkharj sits about 439 m above sea level, so this is an inland town rather than a coastal one, and the owner should focus on water moving through the ground and through cracks in the structure rather than on salt-laden sea air. Because basements are the part of a commercial building most exposed to soil moisture, the owner should expect that a proper fix involves the walls and floor below ground level. Basement waterproofing is priced at SAR 50–150 per m², and crack injection at SAR 40–120 per metre, so the owner can budget by first measuring the affected wall length and area.
A sensible order of work starts with a survey. Mark every damp line, note where cracks run, and check whether the water enters at the wall, the floor joint, or through the roof above a lower storey. Next, deal with the cracks by injection so they are sealed before anything is coated over them. Then choose the surface system: a bitumen membrane at SAR 15–35 per m² is a common choice for buried walls, while epoxy coating at SAR 35–90 per m² suits floors and areas that need a harder, cleaner finish. Spray foam at SAR 20–45 per m² and XPS boards at SAR 12–30 per m² can help where insulation or a drainage layer is also needed. Finish by checking the work after the next rainfall, and keep a dated record of the treated areas so future repairs can be planned.
For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.

How we choose the tool in Alkharj
| Method | What it helps with | Its role in Alkharj |
|---|---|---|
| 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.

Questions from Alkharj
Does an underground tank require waterproofing even if it is new?
Yes, concrete is naturally porous, which can lead to leaks or groundwater seepage. Applying epoxy or cementitious insulation from the start maintains water quality and protects the structure from corrosion.
Do you need to evacuate the building during renovation work?
It depends on the type and scope of the work. Surface work such as plastering and painting usually does not require evacuation, while partial or full evacuation may be advised in cases of structural reinforcement, and the contractor determines this after inspection.
