Why bathroom waterproofing differs in Alula

The centre of Alula sits about 697 m above sea level (SRTM open elevation data). Main roads in or near Alula: King Abdullah Road.

Will a bathroom in an Alula villa really need waterproofing, given how dry the air is? Yes, and the reason is more practical than the climate alone. The centre of Alula sits about 697 m above sea level, and while rain is rare, the bathrooms in your villa still take daily water use, steam and splashing that can seep into floors and walls if the seal is weak. Bathroom waterproofing for villas here is typically priced at SAR 15–40 per m², which makes it one of the more affordable protections a property owner can put in place before tiling is set in place.

A site visit usually begins with a walk around the bathroom to look at the floor falls, the wall junctions and the area around the shower tray and drain. The technician checks the existing surface for hairline cracks, lifted tiles and any old coating that has started to peel. Where cracks are present, crack injection is priced at SAR 40–120 per metre, so the surveyor measures the length of each defect and notes it clearly. If the work involves a shower enclosure with a wet area that needs a continuous membrane, the surveyor also records the total area in square metres, since epoxy coating, spray foam and bitumen membrane are each quoted per m². This gives you a written picture of what needs treatment before any materials are chosen.

Before the visit, gather a few things that will speed up the assessment. Clear the bathroom floor and the space around the shower so the surveyor can reach the walls and drain, and make a note of any past leaks, staining or damp patches you have noticed. If you have the original drawings or the tiling layout, have them ready, as they show where the wet areas sit. It also helps to tell the surveyor whether the bathroom is on the ground floor or above another room, because that affects how the membrane is taken up the walls. With these details in hand, the inspection can move straight to a clear, itemised plan for your villa.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.
