Bathroom waterproofing in Jeddah starts with the location, because the city sits close to the sea. Jeddah is about 2 km from the sea coast (OpenStreetMap), so salty and humid air is a regular part of life for apartments here, and this affects how tiles, grout and the joints around shower trays hold up over time. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data), which means many buildings are not in a low-lying basin, but moisture still gathers in bathrooms that are poorly ventilated. Our technicians therefore check the existing tile lines, the wall and floor junctions, and any old sealant around the bath or shower before quoting a method.
Some points can only be settled at the site visit. The technician will look at the substrate, the condition of any cracks, the slope towards the drain, and whether the bathroom sits above another flat where a leak would be a neighbour's problem. The choice between liquid membrane, epoxy coating, spray foam or a bitumen membrane depends on what is found on the day. Where a crack is active, crack injection may be needed, and that is priced per metre rather than per square metre. Costs given in our price guide are indicative ranges, and the final figure follows the inspection.
To help the technician prepare, please clear the bathroom floor and walls where you can, note any past leaks or repairs, and tell us which floor you live on and what is below. Photographs of the cracks or stains are useful. Please also say whether the flat above you has had water issues, and whether the bathroom has an extractor fan that works. This information lets the visit focus on the real problem rather than starting from scratch.
In apartment buildings, the floor below is often where a leak shows first.

Short answers for Jeddah
Can I use household chemicals instead of calling a technician?
Using unsuitable chemicals may corrode pipes and does not fix the root cause of the blockage, so it is better to rely on a specialist technician.
What is the difference between foam insulation and other types of insulation?
Foam insulation is easy to apply on uneven surfaces and forms one continuous layer with no joints, while other types, such as bitumen rolls, need the joints to be welded. The contractor decides which is most suitable after inspecting the site.
Can thermal insulation be applied to an existing building?
Yes, thermal insulation can be installed on the roofs and walls of existing buildings without the need for major structural modifications. The contractor prepares the surface, then applies the insulating material and the protective layer over it.
