Why roof waterproofing differs in Abu Arish

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 material is chosen for a clinic roof in Abu Arish, the technician checks the drainage and the height of the site. The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data), so the roof is not in a low, flood-prone position, but rainwater still has to leave the roof cleanly through outlets and falls that have been kept clear. Clinics also carry heavy daily foot traffic and equipment loads, so the existing surface, any ponding and any sign of previous patching are reviewed first. Liquid roof waterproofing, bitumen membrane and XPS boards each suit different roof conditions, and the choice follows from what the first inspection shows rather than from a fixed rule.

Some decisions can only be made on the roof itself. The technician walks the full area to judge whether cracks are active or old, whether the upstands and parapets are sound, and whether the membrane lap or joint detail needs reworking. Where cracks are found, crack injection is priced per metre (SAR 40–120 per m), so the length measured on site drives the cost more than any assumption made beforehand. Whether a roof can carry foam, a coating or a new membrane over the existing surface is also a site judgement, as is the condition of any rooftop water tank, which may need internal coating (SAR 25–60 per m²) if it is part of the scope.

Finally, the technician benefits from a clear record before arriving. Useful information includes the roof area in square metres, a note of any leaks reported inside the clinic and the rooms they affect, the position of drains and outlets, and access arrangements that suit a working clinic. Estimates for liquid roof waterproofing (SAR 8–25 per m²), spray foam (SAR 20–45 per m²) and epoxy coating (SAR 35–90 per m²) are easier to refine when the area and the surface type are known. Sharing photos of the roof and the affected ceilings also helps the technician plan the visit efficiently.

For clinics, work is scheduled around patient hours and kept to the areas that need it.

Signs that call for roof waterproofing

These are the signs most often linked to roof waterproofing:

• Water pooling on the roof
• Stains on the top-floor ceiling after rain
• The old waterproofing is cracking

Where the problem usually comes from

• A common cause: wrong falls towards the drains.
• Damaged waterproofing around tank and AC bases.
• Cracks in the roof slab — we check this before anything else.

Tools and methods, and when we use them

The steps in order

1. Survey: Falls, drains and the condition of the old layer are recorded.
2. Preparation: Cleaning and repairs before any new layer.
3. Primer: The base coat that the system needs.
4. Waterproofing layers and details: Corners, upstands and bases get their own detail.
5. Flood test: The roof is flooded and checked before it is covered.
