Does waterproofing a basement in Alrass mean tearing up the floor and walls? Not necessarily. Alrass sits about 695 m above sea level, and many owners here assume that a higher elevation keeps water away from lower levels. In practice, a basement can still take in moisture from the surrounding ground, and the work can often be planned to limit disruption. The pricing on this page gives a clear starting point. Basement waterproofing is priced at SAR 50–150 per m², crack injection at SAR 40–120 per metre, and epoxy coating at SAR 35–90 per m². Which option suits your basement depends on where the water is entering and how the walls are built.

The inspection begins with a walk-through of the basement and the areas around it, looking for damp patches, staining, efflorescence and cracks. The technician will identify where moisture is coming through and whether it runs along a crack, through a wall face or from the floor edge. Crack injection is assessed separately, since it is charged per metre, while surface options such as spray foam at SAR 20–45 per m² or epoxy coating are matched to the area affected. The findings are then explained so you can see which parts of the basement need attention and which do not, before any work is agreed.

Preparation makes the visit faster and more useful. Clear the walls and floor where possible so the surfaces can be examined directly, and move stored items away from damp areas. Note when you have seen water appear, especially after rain or when the ground outside is wet, because this helps locate the source. Have any earlier repair records to hand, including previous coatings or injections. If you know the approximate area of the basement, share it, since rates here are given per square metre and that figure shapes the scope of the quote.

The aim is to locate the cause with instruments first, so any opening is limited to one point.

Signs worth paying attention to

The following signs are worth checking before they grow:

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

The most common causes

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