Floor and balcony waterproofing in Jeddah starts with the location itself. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data), and the city is about 2 km from the sea coast (OpenStreetMap). Because the coast is close, the technician checks first how water moves across and through the slab, and whether rainwater or groundwater is likely to collect at low points. Balconies and external floors are reviewed for drainage falls, outlet positions, and any existing upstands, since these decide whether water runs away from the building or pools against the wall.
Some points can only be settled during the site visit. The technician walks the surface to find cracks, blistered finishes, failed old membranes, and areas where ponding has already occurred. Crack lines are measured in metres so the work can be priced properly, and the choice between injection, spray foam, epoxy coating, or a membrane depends on what is actually found. Where a balcony meets a wall or door threshold, the junction is inspected in person. Access routes, the condition of the substrate, and whether the surface is still damp are also judged on the spot, because these affect the method and the working time.
To help the technician prepare, residents and property managers should note the areas that leak or stay wet after rain, the age of any previous waterproofing, and whether the floor sits above a bathroom, a basement, or an occupied room below. Photographs of stains, cracks, and drainage outlets are useful, as are details of any furniture or fixtures that will need moving. Pricing references for the main methods are listed for planning: spray foam runs SAR 20–45 per m², epoxy coating SAR 35–95 per m², crack injection SAR 40–125 per metre, bitumen membrane SAR 15–35 per m², and liquid roof waterproofing SAR 10–25 per m². Final quotes are issued only after the site visit confirms which method suits the floor or balcony in question.
Each job ends with a written report that carries a verification code you can check on our site.

Tools we use in Jeddah
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
From the first visit to the report
- Checking the falls: Where water collects and where it should go.
- Details: Thresholds, drains and upstands.
- Waterproofing: The layer is applied and protected.
- Flood test: Tested before the finish goes on.

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.
