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).

Floor and balcony waterproofing in Taif begins with the altitude. The centre of Taif sits about 1673 m above sea level (SRTM open elevation data), so the technician's first check is how the surface has been exposed over time to strong sun, sharp temperature swings and dry air. Before any product is chosen, the surface is examined for hairline cracks, blistering, and any sign that old sealant has lifted or split. Balcony slabs and terraces are checked for the way water runs off them, because standing water on a flat surface is the most common cause of leaks reaching the rooms below. Company sites often have long runs of balcony or podium deck, so the team also notes where the work can be staged without blocking daily use.

Some points can only be settled on the site visit. The true condition of the substrate, how deep any cracking runs, whether moisture is rising from below, and the exact falls needed for drainage all depend on what is found when the old finish is opened up. The site visit is also where the right system is matched to the surface. Crack injection is priced per metre, typically SAR 40–115 per m, while the main surface options are priced per square metre: liquid roof waterproofing at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², and epoxy coating at SAR 35–85 per m². Where a balcony sits above an enclosed space, spray foam at SAR 25–45 per m² or XPS boards at SAR 10–30 per m² may be considered. The visit confirms which of these fits the surface, not just the budget.

To help the technician, the company should prepare a few details in advance. Provide the approximate area of each floor or balcony in square metres, a list of any rooms directly below that have shown staining, and a note of when the last waterproofing was carried out. Say whether the balcony is used for foot traffic, planters or equipment, since that affects the finish chosen. Mention any water tanks or basement areas nearby, as tank internal coating runs at SAR 25–55 per m² and basement work at SAR 50–145 per m², and these may be quoted separately. Clear access times and a contact on site will let the work proceed without delay.

For companies, an annual contract sets the scope, the visit schedule and the reports in writing.
