Floor & balcony waterproofing in Jeddah: without breaking
In short: In Jeddah (Jeddah), floor & balcony waterproofing (without breaking) begins with the roof, falls and drains survey and the moisture meter for ceilings and walls; nothing is opened until the position is clear. The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data). Pricing starts from Bathroom waterproofing (per m²) (SAR 15–40 per m²), and other items are quoted after the visit.
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).

Jeddah sits about 15 m above sea level, and its coastline is roughly 2 km away, so the city is close enough to the Red Sea to feel its humidity and salt-laden air, yet high enough that most sites drain naturally rather than pooling. For a floor or balcony waterproofing job, that combination matters. Salt and moisture can work into concrete and tile joints over time, so the surface prep and membrane choice need to account for a damp, saline environment, not just a dry inland one. Drainage gradients are also easier to form on a site that is not flat at sea level, which helps the membrane stay dry at the edges where water tends to sit.
Each of these local conditions has a direct effect on the work. Because the coast is near, we check the substrate for salt residue and dampness before any coating goes down, since trapped moisture is the most common reason a new layer lifts or blisters. Because the ground is not at sea level, we look at falls toward drains and outlets so that the finished surface sheds water rather than holding it. Our crews pay close attention to balcony edges, door thresholds and the junctions with walls, because these are where water in a humid coastal climate finds its way under a finish. Where a site has existing cracks, we treat them first so the new membrane bonds to a stable base instead of moving with the crack.
Owners in Jeddah can avoid several common mistakes that lead to repeat work. The first is coating over a damp or dusty surface, which stops adhesion from the start. The second is skipping the edge and corner details, where most leaks begin. The third is choosing a single product for every area, when a bathroom, a balcony and a roof each face different loads and exposure. The fourth is leaving a fresh membrane open to foot traffic or water before it has fully cured. Keeping to a proper sequence of cleaning, priming, detailing and curing is what keeps a floor dry without tearing up tiles or reopening the job later.
The aim is to locate the cause with instruments first, so any opening is limited to one point.
Signs that call for floor & balcony waterproofing
If you notice one of these signs in Jeddah, it is a good moment to talk to the team:
- Water passing from the balcony to the floor below
- A wrong fall towards the door threshold
- Damp under the light well
Where the problem usually comes from
- A threshold without waterproofing — we check this before anything else.
- Incorrect falls — we check this before anything else.
- A blocked drain.
Tools and methods, and when we use them
| Method | What it helps with | Its role 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 |
The steps in order
- 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.

Questions from 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.
What is the first step of floor & balcony waterproofing (without breaking)?
We start with checking the falls (where water collects and where it should go), then details (thresholds, drains and upstands).
How much does floor & balcony waterproofing cost in Jeddah?
From our published price list: Bathroom waterproofing (per m²) SAR 15–40 per m². Quantities are confirmed at the inspection.
What do I get at the end?
The flood result and photos of the details, in a technical report that carries a verification code.
What we advise against
- Tiling a balcony without waterproofing
What you get after the work
The written output: the flood result and photos of the details. The report is numbered and can be checked with its verification code.
Planning the visit in Jeddah
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
