Before we start: what we know about Sharurah

Team note on Sharurah: 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 Sharurah sits about 724 m above sea level (SRTM open elevation data).

Basement and foundation waterproofing in Sharurah most often starts with water that enters through hairline cracks and the joints between the wall and floor slab. Water tends to appear after rain, then seeps along the wall face and leaves damp patches, efflorescence, or a musty smell. Because the problem is usually a moving or cracked element rather than a uniform surface, a single flood-coat treatment rarely solves it on its own. Before choosing a method, the contractor should confirm where the water is actually coming from.

The local setting changes the approach. The centre of Sharurah sits about 724 m above sea level, which places the town on higher ground than many coastal Saudi cities. That elevation means the ground around a building can shed surface water quickly, but sudden heavy rain still runs off into any low-lying yard, light well, or footing and presses against the lower walls. A good plan therefore looks at how water reaches the basement from outside, not just at the surface inside. Crack injection is often needed where cracks run through the structure, while a membrane or XPS board may be used on the outer face where access allows. Epoxy coatings suit interior surfaces that need a durable, easy-to-clean finish once the source is sealed.

Before the visit, ask the provider a few direct questions. Ask whether they will inspect the outside ground levels, drainage paths, and any cracks, and whether they will explain which method suits each area and why. Ask what is included in the quoted rate per square metre or per metre of crack, and whether preparation, removal of loose material, and cleaning are part of the price. Ask how long the work will take and what the building will need during the process. Finally, ask for a written scope that matches what you discussed, so you can compare it fairly with other offers. Clear answers at this stage usually lead to a more reliable result.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.

Tools and methods, and when we use them

The steps in order

1. Finding the source: Groundwater, rain or a pipe — each needs a different treatment.
2. Preparation: Surfaces are cleaned and opened where needed.
3. Injection: Active cracks are injected.
4. Waterproofing layers: The system is applied on the right side of the wall where possible.
5. Follow-up: Readings are repeated after the treatment.
