Before we start: what we know about Baqiq

Team note on Baqiq: 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 Baqiq sits about 83 m above sea level (SRTM open elevation data).

Is a basement in Baqiq worth waterproofing before the summer heat arrives? For most owners the answer depends on how the space is used and what the foundation has already shown. Baqiq's centre sits about 83 m above sea level, so the site is not low-lying, but a below-ground room still needs a sealed barrier against moisture and seepage. Basement waterproofing is priced at SAR 50–150 per m², with the final figure set by the area, the surface condition and the system chosen. Where cracks are visible, crack injection costs SAR 40–120 per metre, and that repair is usually handled before any wider membrane or coating goes on.

A site visit typically begins with a walk through the basement and the adjoining floors to note damp patches, staining, efflorescence and any active cracks. The inspector measures the affected wall and floor areas so that a quote can be built from the per-square-metre rates. Cracks are marked and their length recorded in metres, because injection is priced per metre. The inspector then checks the surfaces that will receive the treatment, since epoxy coating (SAR 35–90 per m²), spray foam (SAR 20–45 per m²) and bitumen membrane (SAR 15–35 per m²) each need a sound, dry base to perform. Where a water tank or related structure is involved, its internal surfaces are reviewed separately, with tank internal coating priced at SAR 25–60 per m². The result is a written scope that explains which method suits each area and why.

Before the visit, it helps to clear the basement of stored items and move furniture away from the walls so the inspector can reach every surface. Note any past leaks, when they appeared and whether they follow heavy rain, since this history guides the choice of system. Gather any earlier repair records or plans for the building, and say which rooms are used for living or storage, as that affects the priority of the work. If the space connects to a bathroom or the roof, mention those too, because bathroom waterproofing (SAR 15–40 per m²) and liquid roof waterproofing (SAR 8–25 per m²) are often assessed alongside the basement. Having this information ready lets the visit focus on the real problem areas and gives you a clearer picture of the cost before the summer season begins.

Checks before summer and before the rain season catch problems while they are still small.

When do you need basement & foundation waterproofing?

If you notice one of these signs in Baqiq, it is a good moment to talk to the team:

• Water seeping in after rain

• Salt marks at the bottom of the walls

Causes we see in the field

• Cracks at construction joints.
• Rainwater draining towards the foundation.
• A high groundwater level — we check this before anything else.

Tools we use in Baqiq

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.
