Basement & foundation waterproofing for apartments in Riyadh
In short: Basement & foundation waterproofing for apartments in Riyadh starts with the moisture meter for ceilings and walls, then the crack injection (polyurethane or epoxy), before anything is opened. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data). Pricing starts from Crack injection (per metre) (SAR 40–125 per m), and other items are quoted after the visit.

Main roads in or near Riyadh: King Fahd Road, King Abdullah Road, King Abdullah. The centre of Riyadh sits about 637 m above sea level (SRTM open elevation data).
Team note on Riyadh: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins..
Riyadh's climate is hot and dry for most of the year, but flash rains can arrive quickly and push water toward low points, so basements and ground-floor slabs in apartment buildings need steady protection rather than occasional patching. Basement wall treatment is typically priced from 55 to 160 riyals per square meter, and bathroom or balcony floor insulation from 15 to 40 riyals per square meter, which gives a sense of how the scope changes with the area involved. A protective or reflective coating layer ranges from 10 to 30 riyals per square meter and is often added on top of the primary waterproofing.
For this type of property, the first check is where water is actually entering: the team looks at the basement walls, the slab edges and the wet zones above, then traces whether the leak comes from the ground side or from plumbing overhead. Before any work starts, they confirm whether a bathroom leak test requires breaking tiles, because that decides whether the job stays surface-level or becomes more invasive. Checking the source first matters because treating the wrong surface wastes money and leaves the real path of water open.
Before the visit, gather the building's access details, any past repair records, and photos of stains or damp patches taken at different times of day. Ask the team how long the floor needs to dry before it can be used again, what coating is recommended for your exact surface, and whether the quoted rate covers the full area or only the visible section.
In apartment buildings, the floor below is often where a leak shows first.
Signs that call for basement & foundation waterproofing
If you notice one of these signs in Riyadh, 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 common cause: a high groundwater level.
- Rainwater draining towards the foundation — we check this before anything else.
- A common cause: cracks at construction joints.
Tools and methods, and when we use them
| 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 |
From the first visit to the report
- 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.

Short answers for Riyadh
What is the drying time for the floor before use?
The drying time varies depending on the system type, layer thickness, and site temperature. The installer will specify it within the scope of work.
Does detecting bathroom leaks require breaking tiles?
Usually not. Modern tools such as thermal cameras, electronic listening devices, and pressure testing pinpoint the source of a leak with high accuracy. If breaking is necessary, it is limited to the repair point only, after the location has been confirmed.

Planning the visit in Riyadh
- 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.
