Basement & foundation waterproofing for residential buildings in Madinah
In short: In Madinah (Madinah), basement & foundation waterproofing for residential buildings begins with the moisture meter for ceilings and walls and the crack injection (polyurethane or epoxy); nothing is opened until the position is clear. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data). Published price: Crack injection (per metre), SAR 40–120 per m; anything else is quoted after the inspection.
Basement & foundation waterproofing in Madinah: the local context
Team note on Madinah: 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.. The centre of Madinah sits about 589 m above sea level (SRTM open elevation data).
The most common problem with basements and foundations in residential buildings is water seeping through cracks in the lower walls and floor slab, often where the concrete meets the wall or where a construction joint was never properly sealed. Damp patches, peeling paint, a musty smell and efflorescence on the walls are usually the first signs. Left alone, the moisture slowly weakens the finishes and can reach the structure itself, so early attention is far cheaper than repairing damage that has spread.
In Madinah, the centre of the city sits about 589 m above sea level, and that matters for how the work is planned. Ground water and surface run-off behave differently across a city laid out on a gentle slope, so a basement in one district may face pressure from a different direction than one a few streets away. Waterproofing should therefore start with a close look at where water actually enters, rather than a standard layer applied to every wall. Crack injection is typically priced at SAR 40–120 per metre, while basement waterproofing ranges from SAR 50–150 per m², so the choice between targeted repair and full-surface treatment depends on how widespread the problem is. Epoxy coating at SAR 35–90 per m² or a bitumen membrane at SAR 15–35 per m² may suit different wall conditions, and a spray foam or XPS board option at SAR 25–35 or SAR 10–30 per m² can be considered where the approach calls for it.
Before the visit, ask the provider to explain how they will locate the source of water, whether they will inspect the outside of the wall as well as the inside, and which materials they recommend and why. Ask for an itemised quote that shows the area in square metres and the length of any cracks in metres, so you can compare it against the ranges above. Confirm who will prepare the surface, how long the work is expected to take, and what aftercare or inspection will be offered. Clear answers to these questions will help you judge whether the proposed work fits your building.
For a residential building, shared risers, tanks and pumps are checked as one system.

Tools we use in Madinah
| 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 |
How the work is done, step by step
- 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 Madinah
What is the difference between standard spraying and integrated pest management?
Standard spraying treats visible symptoms only, while integrated pest management includes diagnosis, sealing entry points, and multiple methods for longer-lasting results.
Could the leak be caused by weak waterproofing rather than the pipes?
Yes, damage to the waterproofing layer beneath the bathroom floor is one of the most common causes of leaks, especially in older buildings. In this case, water seeps through the tile joints into the screed and then down to the ceiling below. A specialized inspection can distinguish this from a pipe leak.
What is the difference between drain unblocking and drain cleaning?
Unblocking removes an existing blockage that prevents drainage, while cleaning is a preventive procedure that removes deposits and grease from pipes before they cause a blockage.
What is the first step of basement & foundation waterproofing for residential buildings?
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).
