Rising damp and salt staining on the lower walls of residential buildings is the problem most often seen by homeowners in Alkharj, and it usually shows up as peeling paint, a musty smell and white powder rising from the skirting. In many houses the source is water that reaches the wall through the ground, from a bathroom or kitchen that was never sealed properly, or from a roof that lets rain run down into the top floor. Identifying which of these is at work matters, because a surface fix that ignores the real route of water will return within a season.
Alkharj sits at about 439 m above sea level, so the land is not flat in the way coastal cities are, and surface water can move through the ground toward low points around a plot. That is one reason a basement or ground-floor wall may stay damp even after a repaint. For this reason, a good treatment starts with the wall's exposure rather than a single product. Basement walls usually need a full waterproofing system, which typically runs from SAR 50 to SAR 150 per m², while wet rooms such as bathrooms are generally handled with a more targeted system at SAR 15 to SAR 40 per m². Where cracks are the entry point, crack injection is priced per metre, from SAR 40 to SAR 120 per m, and it is best scoped after the wall has been inspected rather than guessed from the photos.
Before the visit, ask the provider to explain which area of the building they plan to treat and what they think is causing the damp, and whether they will look at roof drainage and ground-level water as well as the wall itself. Ask for the method, the materials and the price basis, including whether the figure is per m² or per metre, and whether the quote covers the cost of preparation and making good afterwards. Request to see where similar work was carried out nearby, and ask how they will check the result before handing the job back to you.
For a whole building, a survey of the shared systems comes before unit-by-unit work.

Tools we use in Alkharj
| Tool | What it finds | When we use it 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 |
| 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.

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.

Planning the visit in Alkharj
- 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).
