Before we start: what we know about Aldiriyah

Team note on Aldiriyah: 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 Aldiriyah sits about 655 m above sea level (SRTM open elevation data).

Roof waterproofing for warehouses in Aldiriyah starts with the basics of the site itself. The centre of Aldiriyah sits about 655 m above sea level, which places the area on high ground where roofs take a steady load of sun, dust and temperature swings. Before any product is discussed, the technician checks the existing roof covering, the drainage outlets, and any sections where water has already left a mark on the ceiling below. Liquid roof waterproofing is typically priced at SAR 8–25 per m², while bitumen membrane runs SAR 15–35 per m², so the surface condition helps decide which system suits the roof and the budget.

Several things can only be judged on the day of the site visit. The exact roof area, the slope of each bay, the state of upstand walls and parapets, and the position of skylights and roof-mounted equipment all change the scope of work. Cracks are assessed in person as well, because crack injection is priced per metre at SAR 40–120 per m and the length and depth are not known until someone walks the roof. Where the roof meets a water tank or a stored-water area, the technician will also note whether internal coating is needed, which is priced at SAR 25–60 per m². Insulation is another decision reserved for the visit, since XPS boards at SAR 12–30 per m² are only sensible when the underlying structure and load allow them.

To help the technician arrive prepared, it is useful to gather a few details in advance. Note any past leak locations, the age of the existing roof covering, and whether previous repairs used coatings or membranes. Share the building's approximate footprint, the number of roof levels, and any access limits such as stored goods or active loading areas. Photographs taken after rain are especially helpful, because they show where water actually pools. With this information in hand, the technician can plan the visit efficiently and give a clearer estimate for the roof of your warehouse in Aldiriyah.

For warehouses, work is phased around operations and stored goods.

Signs that call for roof waterproofing

These are the signs most often linked to roof waterproofing:

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

Causes we see in the field

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

How we choose the tool in Aldiriyah

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.
