Is it possible to stop water seeping into a basement in Alkharj without tearing up the whole floor and walls? Often, yes. The centre of Alkharj sits about 439 m above sea level, and a home owner here can choose from several methods that work on the existing structure. Basement waterproofing is typically priced at SAR 50–150 per m², epoxy coating at SAR 35–90 per m², and spray foam at SAR 20–45 per m². Crack injection, which seals a leak at its source, is quoted at SAR 40–120 per metre. Because the costs differ so much, the right method depends on what the inspection finds.
Our inspection starts with a walk-through of the basement and the areas above it, looking for damp patches, efflorescence, and cracks in the walls and floor slab. Each crack is measured in metres so the injection work can be estimated properly. The technician then checks the bathroom and any water tanks, since leaks often start there and travel into the basement. Where the source is unclear, the team identifies the likely entry route before recommending anything. The aim is to match the treatment to the cause, whether that is a crack, a bad joint, or water pressing in from outside. You will receive a written summary of what was found and which options fit the findings, with the ranges listed above.
Before the visit, clear as much of the basement as you can so the walls and floor are reachable, and move any stored items away from damp areas. Note when the leaks appear, for example after rain or when a nearby tap or tank is used, because this timing helps narrow the cause. Take photos of any staining or cracks, and tell us about any previous repairs, including what material was used. If the roof or the bathroom above the basement has also been leaking, mention it, as these are often linked. Having this information ready lets the inspection focus on the real problem and keeps the disruption to your home to a minimum.
The aim is to locate the cause with instruments first, so any opening is limited to one point.

Short answers for 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.
