Before we start: what we know about 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).

Picture the owner of a small office block or a mid-sized commercial complex in Abu Arish. Their washrooms are used all day by staff and visitors, the tiling takes constant wet traffic, and a leak that starts on an upper floor can quietly reach the ceilings below before anyone notices. The owner wants the work done once, done properly, and with as little disruption to tenants as possible. Bathroom waterproofing is usually one of the first jobs they schedule when they plan maintenance, because the cost of damaged finishes and lost use of facilities adds up quickly.

The centre of Abu Arish sits about 67 m above sea level, according to SRTM open elevation data. For a building owner, this elevation means the site is not in a low-lying hollow where surface water collects, so the priority is usually protecting the interior from water used inside the building and from rain running off roofs and across paved areas. It also means the owner should check how drainage falls away from the building and whether gutters and outlets are clear before any coating is applied. Bathroom waterproofing for a commercial property typically falls within the range of SAR 15–40 per m², so the owner can budget against that band while getting site-specific quotes for the actual area and condition.

A sensible sequence starts with a survey of the bathrooms, the floor beneath them, and any cracks in adjacent walls. Crack injection, priced at SAR 40–120 per metre, should be carried out before the main membrane so that the surface is sound. Next, the floor and wall substrate is cleaned and dried, then the chosen system is applied: an epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², or a bitumen membrane at SAR 15–35 per m², depending on the detail required. Finally, the owner arranges a flood or water test over the treated area for a set period, records the result, and only then allows tiling or finishing to proceed. Keeping this order protects the investment and gives the owner a clear record for future maintenance.

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