Bathroom waterproofing for apartments in Taif

Why bathroom waterproofing differs in Taif

The centre of Taif sits about 1673 m above sea level (SRTM open elevation data). 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..

Bathroom waterproofing in Taif begins with the altitude. The centre of Taif sits about 1673 m above sea level (SRTM open elevation data), which means the air is thinner and cooler than in coastal cities, and the temperature swings between day and night can be wider. Our technicians therefore check first how the existing screed, tiles and grout have moved over time, because thermal expansion at this height can open hairline gaps around the shower tray, the floor-to-wall joint and the drain. Before any product is chosen, the surface is tested for dampness, loose tiles and older sealant that has lost its grip.

Some points are left to the site visit, because they depend on what is found in your particular flat. The technician will confirm whether the bathroom needs a bitumen membrane, a liquid system or a spray foam layer, and will look at the condition of the floor below if the flat is on an upper level. Cost is also set on site: bathroom waterproofing is priced at SAR 15–40 per m², while epoxy coating is SAR 35–85 per m² and spray foam SAR 20–45 per m², so the final figure depends on the chosen system and the measured area. Any crack that needs injection is priced separately at SAR 40–115 per metre, and the visit is the moment to measure these runs and agree them with you.

To help the technician arrive prepared, please clear the bathroom floor and the area under the sink, and note any past leaks, stains on ceilings below, or previous repairs. Tell us whether the water heater or storage tank sits in the bathroom or the adjoining room, because internal tank coating is priced separately at SAR 25–55 per m². Keep access to the drain and the shower valve open, and let us know if the flat has a roof terrace above, since liquid roof waterproofing at SAR 10–25 per m² would be a different job. Clear information at this stage keeps the visit short and the quotation accurate.

In apartment buildings, the floor below is often where a leak shows first.

Signs worth paying attention to

The most common causes

• The area around the floor drain — we check this before anything else.
• A common cause: corners without waterproofing tape.
• A damaged floor layer — we check this before anything else.
