Before we start: what we know about Qatif

Team note on Qatif: 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 Qatif sits about 5 m above sea level (SRTM open elevation data).

Qatif is about 2.5 km from the sea coast (OpenStreetMap).

Do floor and balcony waterproofing needs change when a company runs its premises in Qatif? The short answer is yes, and the reason starts with the location. The centre of Qatif sits about 5 m above sea level, and the town is about 2.5 km from the sea coast. Because of that closeness to the coast, business owners should treat salt-laden air and ground moisture as ordinary conditions to plan for, not rare events. Floors and balconies that carry staff, stock and foot traffic need a membrane that can handle both wear and damp.

Our inspection starts with a walk through every floor area and balcony to note cracks, ponding spots, drainage outlets and any place where water already shows through to the level below. We mark the lines of cracks and measure their length so the work can be priced per metre where injection is needed, and we record the surface area in square metres for the coating or membrane options. The team then checks the edges where floors meet walls and balcony rails, since these joints are the most common route for leaks. Based on what we find, we set out the options that suit the area, such as epoxy coating, spray foam, bitumen membrane or crack injection, each with its own per-square-metre or per-metre rate, so you can compare them before any work begins.

Before the visit, please gather a few details that make the inspection faster and the quote more accurate. Note which floors and balconies have leaks, when the problem first appeared and whether it gets worse after rain or heavy cleaning. Have the total floor and balcony area ready, if you know it, and point out any areas used for storage, traffic or equipment, since heavy use changes the choice of coating. Clear access to drains and outlets helps us check them properly. Finally, let us know when your premises can be closed off for work, so the schedule fits your operations and disruption stays as small as possible.

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