The most common problem with floor and balcony waterproofing in Alkharj is water getting under tiles and into the slab at the joints, edges and drain points, usually after years of heat cycling has opened small cracks. Balconies are especially exposed because rain runs off them toward the wall, and a surface that looks sound can still let water through to the room below. Many owners only notice the damage once staining or damp patches appear on a ceiling, by which point the problem has spread.
Alkharj sits at roughly 439 m above sea level, so the approach here is shaped by a dry, hot climate with sharp daily temperature swings and occasional heavy rain. That combination makes the surface expand and contract, which is why a flexible system is often more suitable than a rigid one. Options such as liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m² and spray foam at SAR 20–45 per m² can each be considered depending on the slab and the drainage. Where cracks are the main issue, crack injection at SAR 40–120 per metre addresses the source before a new layer is applied. Works should be planned so that the floor or balcony can be used again without long disruption, and the method should be matched to the surface rather than applied by default.
Before the visit, ask the provider to explain which area they will treat and why, and to walk the balcony or floor with you to locate cracks, low points and drain outlets. Ask what membrane or coating they propose, how the edges and upstands will be sealed, and how the surface will be prepared. Request a written quote that lists the rate per square metre or per metre of crack, so you can compare line by line. Ask how long the area should be kept clear after completion and what aftercare you should expect. A clear answer to each of these questions is a good sign that the visit will be useful.
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.
