Before we start: what we know about Taif

Team note on Taif: 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 Taif sits about 1673 m above sea level (SRTM open elevation data).

Before any material is chosen for an office or commercial floor or balcony in Taif, the first thing checked is the altitude. The centre of Taif sits about 1673 m above sea level (SRTM open elevation data), a height that brings cooler nights and wider daily temperature swings than the coastal cities. Those swings stress surfaces and joints, so the technician looks first at existing cracks, the condition of the slab edges, and how water currently drains off balconies and across floor areas. The published rates for this work are also set per square metre, with liquid roof waterproofing at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², epoxy coating at SAR 35–85 per m², and spray foam at SAR 20–45 per m², so the measured area and the chosen system must be confirmed on site before any figure is agreed.

Several points can only be settled at the site visit. The technician checks the substrate moisture, the slope and ponding areas, the depth and width of any crack, and whether a crack needs injection, which is priced per metre at SAR 40–115 per m. Access for trafficking, the presence of tenants or equipment, and whether work can happen in shifts all affect the approach. Where balconies meet walls or doors, the junctions are inspected in person, because the correct detailing depends on what is actually built there rather than on what the drawings suggest. Any area that might sit below ground or near a water tank is noted separately, since basement waterproofing (SAR 50–145 per m²) and tank internal coating (SAR 25–55 per m²) follow different requirements.

To help the technician prepare, the client should provide the floor plans with balcony and slab areas marked, any previous waterproofing records, and notes on past leaks, including the rooms or ceilings where water appeared. Photographs of cracks, drainage outlets and the balcony edges are useful, as are details of how the space is used day to day. Insulation options such as XPS boards (SAR 10–30 per m²) are discussed only once the moisture picture is clear. Clear information at this stage lets the technician arrive with a sensible scope and avoids surprises once the work begins.

For offices and commercial complexes, work is scheduled to avoid disrupting staff and visitors.
