Bathroom waterproofing in villas in Alkharj most often fails at the floor-to-wall junction and around shower drains, where small gaps let water seep into the slab and the walls behind tiles. By the time staining or a soft patch shows on a neighbouring room, the leak has usually been moving for a while. Checking these joints first is the most useful starting point for any villa bathroom.
Alkharj sits at about 439 m above sea level, which matters for how a bathroom is approached. Work here is planned around a stable inland climate rather than coastal salt exposure, so the main concern is sealing the bathroom floor and the first few courses of wall against standing water and daily cleaning, not against heavy corrosion. Bathroom waterproofing is priced at SAR 15–40 per m², and the right product within that range depends on the substrate and how much movement the slab shows. Where the floor has hairline cracks, a crack injection at SAR 40–120 per metre may be needed before any surface membrane is laid, so the cracks are sealed from underneath rather than just covered. Where the bathroom sits above a habitable space, the choice between a liquid membrane and a bitumen layer should be made with that in mind.
Before the visit, ask the provider to confirm the area to be treated in square metres and how many linear metres of cracks they expect to find. Ask which product they propose for the floor and for the walls, and whether the price per m² includes surface preparation and tiling reinstatement. Request a clear explanation of how the shower drain and pipe penetrations will be sealed, since these are the most frequent weak points. Also ask how long the area must stay unused after the work and what testing is done before the bathroom is returned to use. Written answers to these questions make it easier to compare quotes on a like-for-like basis.
In a villa, tanks, the roof and the yard lines are usually yours to look after, so it helps to know where the main valve and tank hatches are.

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.
