Floor & balcony waterproofing for villas in Abu Arish

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).

The first thing a technician checks in Abu Arish is the ground the villa sits on, because the centre of the town sits about 67 m above sea level according to SRTM open elevation data. That height means the site is not a low-lying flood zone, so the first question is usually how water moves across the plot and off the roof and balcony surfaces rather than whether it will pool from below. Before any price is discussed, the technician walks the floor and balcony to look for slope, ponding, drainage outlets and the condition of existing screeds and tiles, since these decide which system will hold up. Floor and balcony work is quoted by the square metre, so the surface area and its edges are measured at this stage too.

Several things are left to the site visit because they cannot be judged from a description or a map. These include the actual moisture in the slab, whether cracks are still moving, the state of old membranes, the type of substrate under the tiles, and how the balcony edges meet the wall. Crack injection is charged per metre, so the length and depth of each crack must be confirmed on the ground, and a sound surface may suit a liquid roof system or a bitumen membrane while a damaged one may need epoxy or spray foam. The technician also decides whether bathroom waterproofing belongs in the same job, since it is priced separately per square metre, and whether any XPS insulation boards are needed beneath a finish.

Information that helps the technician is simple and worth gathering before the visit. Note how long the leak or damp has been present, where it shows up inside the villa, and whether the problem is worse after rain. Share the approximate size of each floor and balcony area, the number and length of visible cracks, and any previous repairs or coatings. If a water tank sits on the property, mention it, because tank internal coating is priced per square metre and is handled as its own item. Clear photos of the surfaces, taken in daylight, let the technician prepare the right materials and tools and reduce the number of return trips.

Villas often have several lines and tanks; we test them one at a time so the cause is clear.
