The most common problem with floor and balcony waterproofing in apartments is water getting into the slab below through hairline cracks and failed joints at the edges. On balconies, water often sits against the threshold to the living room and slowly seeps into the ceiling of the flat below, so the damage first shows as stains or peeling paint on a neighbour's ceiling. Inside the flat, the same thing happens around bathroom floors, where tiles and grout let water pass into the structure. Because the leak travels, the visible sign is often far from its real source, which is why a proper inspection matters more than a quick surface patch.
Alkharj sits at a fairly high elevation, with the centre about 439 m above sea level, and the approach reflects that. Rain in the region tends to arrive in short, heavy bursts rather than long soaks, so water pools on balconies and runs quickly toward drains and joints. This favours solutions that bridge small movement in the slab and seal the surface completely. For balconies and open terraces, liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² are common options, while epoxy coating at SAR 35–90 per m² suits floors that take foot traffic and need a tough finish. Crack injection at SAR 40–120 per metre is often needed first, because a crack left unsealed will defeat any coating laid over it. Bathrooms usually fall within SAR 15–40 per m² for waterproofing.
Before the visit, ask the provider which of these methods they propose and why, and request an itemised quote that states the per-m² or per-metre basis for each line. Ask whether they will check the ceiling below a leaking balcony or bathroom, since that is where the evidence usually sits. Confirm how they will prepare the surface, how crack injection will be handled, and how long the coating needs to cure before it is walked on. Ask whether the work includes protecting drains and thresholds. A clear, specific answer to these questions tells you more about the job than any general promise.
In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.

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.
