Bathroom waterproofing work in Qatif starts with the location itself. The centre of Qatif sits about 5 m above sea level, and the town is about 2.5 km from the sea coast. Because of this, technicians check first how water moves through the ground and the walls of a villa, and whether moisture from the coastal air is reaching the bathroom floor and the lower wall lines. This first look shapes which system is suggested, so it is the step we never skip, even on a small job.

Some points can only be settled on the day of the site visit. The technician will walk the bathroom, check the existing tiles, the drain position, the slope of the floor and any signs of old leaks or cracked grout. The condition of the substrate, whether the surface is sound, and whether a coating or a membrane is the better fit are all judged in person. The site visit is also where the scope of the work is agreed, including whether the job covers only the bathroom or links to nearby areas such as a basement or a water tank. Where a basement or tank is involved, the rates for those works differ, so the scope is confirmed before any figure is given.

Information that helps the technician is simple to prepare. Tell us the approximate size of the bathroom and any adjoining wet area, the floor and wall finishes already in place, and any history of damp or staining. Photographs of the walls and floor, the position of the shower and drain, and the age of the villa are all useful. If there is a visible crack, note where it runs. Having access to the bathroom at the agreed time, with the water supply available for a test, lets the technician complete the check in one visit and explain the options clearly for your villa.

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