Floor and balcony waterproofing in Alkharj starts with the site's position. The centre of Alkharj sits about 439 m above sea level (SRTM open elevation data), so a technician will look at how water moves across a balcony or floor slab rather than assuming it will drain away on its own. Check first whether the balcony falls towards the drain outlet or whether standing water collects in a low corner. Next, look at the joint where the balcony meets the wall, because that junction is where leaks most often start. Record any cracks in the slab and note whether they are active or old.
Several points are left to the site visit, because they cannot be judged from a description. The technician needs to see the existing surface, whether it is tile, screed or bare concrete, and whether the tiles are bonded or hollow. The condition of the upstand, the height of the threshold and the state of old sealant also need to be checked in person. Moisture readings on the wall below the balcony help show whether water is entering from above. The choice between liquid roof waterproofing, bitumen membrane, epoxy coating or spray foam depends on what is found on site, and the published ranges below only show what each system typically costs per square metre: liquid roof waterproofing SAR 8–25 per m², bitumen membrane SAR 15–35 per m², epoxy coating SAR 35–90 per m², and spray foam SAR 20–45 per m². Where a crack needs treatment rather than a full coat, crack injection is priced at SAR 40–120 per m.
To help the technician arrive prepared, tell us the approximate area of the floor or balcony in square metres, the length of any visible cracks in metres, and whether the space is an open balcony, a covered terrace or an interior bathroom floor. Mention any previous repairs, any tiling that was added after the original slab, and whether water has ever come through into a room below. Photographs of the surface and of any staining on the ceiling below are useful. With these details, the visit can focus on the right system for the space rather than on a general inspection.
Prices shown on this page come from our own published price list for the city; the final price is set after inspection.

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.
