Basement & foundation waterproofing for rest houses & farms in Jeddah
In short: In Jeddah (Jeddah), basement & foundation waterproofing for rest houses & farms begins with the moisture meter for ceilings and walls and the crack injection (polyurethane or epoxy); nothing is opened until the position is clear. Jeddah is about 2 km from the sea coast (OpenStreetMap). Pricing starts from Crack injection (per metre) (SAR 40–125 per m), and other items are quoted after the visit.
What is specific about Jeddah for basement & foundation waterproofing
Jeddah is about 2 km from the sea coast (OpenStreetMap). The centre of Jeddah sits about 15 m above sea level (SRTM open elevation data).

Basement and foundation waterproofing for rest houses and farms in Jeddah usually comes down to water finding its way in from the ground. The most common problem we see is seepage through the walls and floor of a basement or ground-level store room, often after heavy rain when the soil around the structure is saturated. Rest houses and farm buildings tend to have older concrete and visible hairline cracks where the foundation meets the soil, and these are the usual entry points. Left alone, damp patches spread, salts appear on the walls, and timber or stored goods suffer.
Local conditions shape how we approach the job. The centre of Jeddah sits about 15 m above sea level, so ground water does not always collect in the same way it would on lower coastal land, but the city is still only about 2 km from the sea coast, which means the soil around many properties can stay damp and salty. That combination matters for the choice of system. For a basement wall, a bitumen membrane (SAR 15–35 per m²) or an epoxy coating (SAR 35–95 per m²) may suit a sealed surface, while spray foam (SAR 20–45 per m²) can be considered for certain enclosed areas. Visible cracks are usually treated first with crack injection, priced at SAR 40–125 per metre, before any surface system goes on. Basement waterproofing itself is typically quoted at SAR 55–160 per m², and the final figure depends on access, the condition of the substrate and the type of finish needed. For farm water tanks, a tank internal coating at SAR 25–65 per m² is a separate job and should be quoted on its own.
Before the visit, ask the provider to walk the property with you and to explain where they expect the water to be coming from, not just where it shows. Ask which system they propose for each surface and why, and whether crack injection is included or priced separately. Request a breakdown of the area being treated in square metres and the length of cracks in metres, so you can compare quotes on the same basis. Ask how the work will be prepared, what happens to stored items during the job, and whether the soil outside will be considered as part of the fix. A clear, itemised answer to these questions tells you more than any single price.
Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.
When do you need basement & foundation waterproofing?
If you notice one of these signs in Jeddah, it is a good moment to talk to the team:
- Salt marks at the bottom of the walls
- Damp basement walls
- Water seeping in after rain
Where the problem usually comes from
- A high groundwater level.
- A common cause: rainwater draining towards the foundation.
- A common cause: cracks at construction joints.
Tools we use in Jeddah
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Crack injection (polyurethane or epoxy) | Stopping active water through cracks | Limits: treats the crack, not the water source |
| 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
- Finding the source: Groundwater, rain or a pipe — each needs a different treatment.
- Preparation: Surfaces are cleaned and opened where needed.
- Injection: Active cracks are injected.
- Waterproofing layers: The system is applied on the right side of the wall where possible.
- Follow-up: Readings are repeated after the treatment.

Common questions about basement & foundation waterproofing in 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 basement & foundation waterproofing for rest houses & farms?
We start with finding the source (groundwater, rain or a pipe — each needs a different treatment), then preparation (surfaces are cleaned and opened where needed).
How much does basement & foundation waterproofing cost in Jeddah?
From our published price list: Crack injection (per metre) SAR 40–125 per m; Basement waterproofing (per m²) SAR 55–160 per m². Quantities are confirmed at the inspection.
What do I get at the end?
The source, the treatment and the follow-up result, in a technical report that carries a verification code.
Common mistakes we see
- Painting the basement wall while the water comes from outside
The written outputs
The written output: the source, the treatment and the follow-up result. The report is numbered and can be checked with its verification code.
If you live in Jeddah and are new to the area
- 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.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- 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).
