What is specific about Alaflaj for basement & foundation waterproofing

The centre of Alaflaj sits about 536 m above sea level (SRTM open elevation data).

Is water seeping into your basement after rain, and how do you know whether the fix is worth the cost? In Alaflaj, the centre of the town sits about 536 m above sea level according to SRTM open elevation data, and that elevation is one of the context points we use when a property owner asks why damp appears in some plots and not others. Waterproofing work here is priced by area and by length, so the first step is knowing what your problem actually measures. Basement waterproofing is quoted at SAR 50–150 per m², crack injection at SAR 40–120 per metre, and epoxy coating at SAR 35–90 per m², so a clear measurement of the affected wall and floor area gives you a realistic starting point before any work is agreed.

A site visit in Alaflaj usually begins with a walk around the outside of the building to note ground levels, drainage paths and any visible cracks in the foundation or external walls. The inspector then moves inside to check the basement walls and floor for damp patches, efflorescence and the exact line of each crack, measuring the length of every crack in metres and the total surface area needing treatment in square metres. Bathrooms, roof surfaces and water tanks are checked separately, since their rates differ: bathroom waterproofing runs SAR 15–40 per m², liquid roof waterproofing SAR 8–25 per m², and tank internal coating SAR 25–60 per m². Each area is recorded so the quote matches what was actually found, with no surprises once the work begins.

Before the visit, gather any earlier repair records, a rough sketch of the building with the basement and roof areas marked, and notes on when water first appeared and whether it follows heavy rain. If you already know the length of visible cracks, write them down in metres, and if you have a water tank, note its size so the internal coating can be estimated. Clear access to the basement, roof hatch and tank lid will save time on the day. Keep the list of questions you want answered, such as which option suits your budget and how the different materials compare, so the discussion stays focused and the final choice reflects your property's real needs.

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

• A common cause: cracks at construction joints.

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.
