Basement & foundation waterproofing in Abu Arish: the local context

Team note on Abu Arish: 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 Abu Arish sits about 67 m above sea level (SRTM open elevation data).

Before any work starts on a basement or foundation in Abu Arish, the first thing to check is how the ground sits around the building. The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data), so the land is not a flat bowl where water collects by default. What matters more on the ground is the direction the surface falls away from the structure and whether rainwater is being pushed toward the walls or carried clear of them. The technician will look at ground levels, existing drains, and any sign of water tracking down the outside of the wall, because these tell them where pressure is likely to build against the basement.

Some decisions are left for the site visit itself, since they depend on what is actually in front of the crew. Whether a basement needs full tanking, a membrane, or a simpler approach depends on the wall condition, the presence of cracks, and how water is moving through the structure. Crack injection is priced per metre, typically in the range of SAR 40–120 per m, so the length and location of cracks has to be measured on the day rather than estimated from a drawing. Costs for the main systems also vary widely: basement waterproofing runs SAR 50–150 per m², epoxy coating SAR 35–90 per m², and bitumen membrane SAR 15–35 per m², so the chosen system and the extent of the surface will be settled only once the wall has been inspected.

To help the technician arrive prepared, it is useful to have a few things ready. Note any past water entry, the season when it happens, and where the damp patches appear on the walls and floor. Share access details for the basement and any adjoining areas, and say whether the space is used for storage, a bathroom, or a water tank, since a tank needs internal coating at SAR 25–60 per m², which is a different scope from a dry store. Mark where drains and pipes pass through the basement walls. Clear, honest answers to these points let the visit move quickly and keep the quote tied to the real condition of the building.

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

When do you need basement & foundation waterproofing?

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

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

Tools and methods, and when we use them

From the first visit to the report

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.
