Floor & balcony waterproofing in Jeddah: preventive periodic check
In short: Floor & balcony waterproofing (preventive periodic check) in Jeddah starts with the roof, falls and drains survey, then the moisture meter for ceilings and walls, before anything is opened. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data). Published price: Bathroom waterproofing (per m²), SAR 15–40 per m²; anything else is quoted after the inspection.
Before we start: what we know about Jeddah
The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data). Jeddah is about 2 km from the sea coast (OpenStreetMap).

Floor and balcony waterproofing in Jeddah starts with the location itself. The centre of Jeddah sits about 15 m above sea level, and the city is about 2 km from the sea coast. Because of that proximity, the first thing a technician checks is the condition of the existing surface where salt-laden air and rain can reach it, including balcony edges, floor joints, and the points where tiles meet walls. Water that has been sitting on a slab for a long time often shows itself first as staining on the ceiling below, faint efflorescence on the surface, or softened grout lines, and these signs guide where the inspection begins.
Some parts of the check are left to the site visit, because they cannot be judged from a description alone. The technician will look at the actual slope of the floor and whether it drains toward outlets, the state of any hairline cracks and how far they run, and whether the existing membrane, if one is present, is lifting, blistered, or cracked. The choice of method also depends on the surface: a balcony with heavy foot traffic is treated differently from a rarely used roof section. Any price a client is shown is a range, and the final figure is set only after the visit. Typical reference ranges include liquid roof waterproofing at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², spray foam at SAR 20–45 per m², and epoxy coating at SAR 35–95 per m², and crack injection at SAR 40–125 per metre, but the chosen system is confirmed on site.
To help the technician, it is useful to have the following ready before the visit: the age of the building and any earlier waterproofing work, the location of drains and outlets, a note of where leaks have appeared inside the home, and any photos of cracks or staining taken after rain. Tell the team which areas are used most, such as balconies for seating or washing, since that affects the surface chosen. Clear access to the balcony or floor, and a rough idea of which rooms sit directly below, will allow a faster and more accurate assessment. This preparation makes a periodic check more useful and keeps the preventive work focused on the places most likely to need attention.
Preventive checks follow a written schedule instead of waiting for a fault.
Signs that call for floor & balcony waterproofing
The following signs are worth checking before they grow:
- Water passing from the balcony to the floor below

Causes we see in the field
- A threshold without waterproofing.
- A common cause: incorrect falls.
- A blocked drain.
How we choose the tool in Jeddah
| Tool | What it finds | When we use it in Jeddah |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
How the work is done, step by step
- 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.
