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..

Sharurah sits in the Asir foothills of southwestern Saudi Arabia, with the centre of the town about 724 m above sea level according to SRTM open elevation data. That height places the town on sloping ground rather than a flat plain, so rainwater and groundwater do not always settle in one place. For basement and foundation work, this means water can move laterally through the soil toward lower-lying walls, and a waterproofing plan has to address pressure from more than one direction.

Because of this terrain, the practical starting point is a clear inspection of where water is likely to reach the structure. Crack injection is priced per metre, at SAR 40–120 per m, so the length of visible cracking drives the cost of that part of the job. Basement waterproofing is priced per m², at SAR 50–150 per m², which reflects the wall and floor area that must be treated. Owners who measure cracks and wall areas before requesting quotes can compare offers more easily and avoid paying for coverage they do not need. On sloping sites, a membrane or coating is usually paired with repairs to cracks so that the surface treatment has a sound base to bond to.

Several common mistakes are worth avoiding. Owners often treat only the visible wet patch and ignore the wider wall, even though water can track along the structure. Others choose the lowest per-m² rate without asking what the work includes, which can leave gaps where walls meet floors. Bathroom and tank surfaces are also sometimes overlooked: bathroom waterproofing is priced at SAR 15–40 per m², and tank internal coating at SAR 25–60 per m², so these areas deserve the same attention as the basement. Finally, many owners skip the roof, where liquid roof waterproofing at SAR 8–25 per m² or bitumen membrane at SAR 15–35 per m² can prevent water from reaching the walls below. Planning every surface together helps protect the whole building.

Each job ends with a written report that carries a verification code you can check on our site.

When do you need basement & foundation waterproofing?

These are the signs most often linked to basement & foundation waterproofing:

• Damp basement walls
• Salt marks at the bottom of the walls
• Water seeping in after rain

Causes we see in the field

• Rainwater draining towards the foundation — we check this before anything else.
• A common cause: a high groundwater level.
• A common cause: cracks at construction joints.

Tools and methods, and when we use them

From the first visit to the report

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.
