Floor and balcony waterproofing in Alkharj most often fails at the joints and edges rather than across open surfaces. Water tends to find its way in where the floor meets the wall, around drainage outlets, and along cracks that open up as concrete moves with temperature. By the time damp shows on a ceiling below, the problem has usually been developing for some time. For balconies, the usual weak point is the upstand where the tiling stops and the membrane has to turn up against the wall.
The centre of Alkharj sits about 439 m above sea level (SRTM open elevation data), which means the town is not a low-lying hollow where rainwater pools for long periods. Even so, the approach should still focus on how water moves across the slab. Good preparation of the substrate, proper falls toward drains, and well-sealed upstands matter more than the choice of product alone. Costs vary with the system used: a liquid roof waterproofing system typically runs SAR 8–25 per m², a bitumen membrane SAR 15–35 per m², and a spray foam layer SAR 20–45 per m². Crack injection, where cracks need sealing before any surface treatment, is priced at SAR 40–120 per metre. Bathroom-adjacent floors often call for a different specification, at SAR 15–40 per m².
Before the visit, ask the contractor to identify which system they propose and why it suits your specific slab, balcony or floor. Ask how they will prepare the surface and treat the cracks and upstands, and whether the price quoted is per square metre and includes the crack work. Request a written scope that states the area measured and the length of any cracks to be injected. Ask to see examples of similar work on this property type, and check how they plan to protect the finished surface from foot traffic during curing. A clear answer to each of these questions will tell you far more than a headline price.
Before buying or taking over a property, an inspection gives you findings in writing before you sign.

Common questions about floor & balcony waterproofing in 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.
