Is a damp basement in an apartment building in Qatif something I can ignore until it gets worse? Usually not. The centre of Qatif sits about 5 m above sea level, and the town is about 2.5 km from the sea coast. That combination of low elevation and nearby coastal conditions means moisture can build up in below-grade walls and floors, so a basement or foundation problem deserves prompt attention. Basement waterproofing here is typically priced at SAR 50–150 per m², while crack injection, which is priced per metre rather than per square metre, usually runs SAR 40–120 per m. Epoxy coating, spray foam, and bitumen membrane are other options that a site visit can help you compare for your particular walls and floors.

When a technician visits, the work usually begins with a walk through the basement or foundation area to look for staining, efflorescence, cracks, and areas where water is collecting. They will note where the cracks run and how long they are, since crack injection is measured by the metre, and they will measure the affected wall and floor areas in square metres so the quote matches the actual surface. Where a basement is used alongside a bathroom or tank, the inspection can also cover those spaces, because bathroom waterproofing and tank internal coating are each priced separately, at SAR 15–40 per m² and SAR 25–60 per m² respectively. The goal of the inspection is to separate the problem areas from the ones that are only cosmetic, so the proposed work fits what is actually wrong.

To make the visit productive, it helps to have a few things ready. Note any places where you have seen damp patches, peeling paint, or water after rain, and take photographs if possible. Clear the basement floor and the walls near the problem areas so the technician can see the surface directly, and let them know whether the space is used for storage, parking, or living purposes. If there are previous repair records or any earlier waterproofing work, bring those along, as they show what has already been tried. Finally, confirm who will be present to approve the scope and the cost, so that the quote can be discussed and decided during the same visit.

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