Before we start: what we know about Sakaka

Team note on Sakaka: 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 Sakaka sits about 555 m above sea level (SRTM open elevation data).

Does a basement in an apartment building in Sakaka really need waterproofing, given how dry the region is? The short answer is yes. Sakaka sits at about 555 m above sea level, and it is the rain and seepage that find weak points in a basement wall or floor, not the altitude itself. Basement waterproofing is priced at SAR 50–150 per m², and the wide range reflects how much work the existing structure needs. Crack injection, priced at SAR 40–120 per metre, is often the first repair when a crack is the source of moisture.

Our inspection starts by walking the basement with the owner or building manager to find damp patches, efflorescence, staining and any visible cracks. The technician measures the affected wall and floor areas so the quote can be calculated per square metre, and marks each crack so its length can be priced per metre. Where water is entering through a joint or a crack, that point is recorded first, because stopping the entry matters more than covering the surface. Bathrooms and roofs above the basement are checked too, since a leak higher up can look like a basement problem. Each finding is then matched to a method, such as a bitumen membrane at SAR 15–35 per m², XPS boards at SAR 12–30 per m², or epoxy coating at SAR 35–90 per m², and the recommendation is explained before any work is agreed.

Before the visit, please clear the basement wall and floor areas as far as practical so the surfaces can be seen clearly. Note when you first noticed the damp and whether it appears after rain, during the summer, or all year, because this helps identify the source. Gather any earlier repair records or invoices for the building, and tell us about any water tanks stored in the basement, since tank internal coating is priced separately at SAR 25–60 per m². Having this information ready means the inspection can focus on the real problem and the quote can reflect the actual work needed for your apartment building in Sakaka.

In an apartment, a problem may start in your unit or in a shared line; we separate the two before any work.
