Floor & balcony waterproofing in Dammam: the local context

Team note on Dammam: 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 Dammam sits about 12 m above sea level (SRTM open elevation data).

Dammam is about 4.3 km from the sea coast (OpenStreetMap).

Floor and balcony waterproofing for restaurants in Dammam starts with the location itself. The centre of Dammam sits about 12 m above sea level according to SRTM open elevation data, and the city is about 4.3 km from the sea coast according to OpenStreetMap. Because a restaurant floor is often wet from cleaning, spills and grease, the first check is always whether water can reach the slab from above and collect at low points, rather than whether groundwater is a concern. Technicians look at drainage falls, floor drains, skirting joins and the edges where the floor meets walls, since these are where standing water usually does damage in a commercial kitchen or dining area.

Several items can only be settled on the site visit. The condition of the existing screed, the presence of hairline cracks, and whether moisture is rising from below all need hands-on inspection before any product is chosen. The technician will also confirm the exact area to be treated, the state of any old membrane, the balcony edge details and how the surface will be used once the work is finished, such as heavy equipment, chair movement or frequent mopping. Pricing for the work is normally set after these measurements, so the visit is the point where the scope is fixed. Indicative ranges elsewhere on the site, such as epoxy coating at SAR 35–90 per m² or spray foam at SAR 25–35 per m², are only starting references and do not replace the on-site assessment.

To help the technician prepare, it is useful to have a plan or sketch of the floor showing drains, service pipes and any balcony with its door positions. Please note which areas stay wet during service hours and whether the kitchen must stay closed during work. Photographs of cracks or past leaks, and a note of when the problem first appeared, make it easier to decide between a liquid membrane, a bitumen layer or crack injection, which is charged at SAR 40–120 per metre. Clear access times and a contact person on site allow the work to be planned around opening hours and keep disruption to a minimum for the restaurant team.

For restaurants, visits are planned outside service hours and recorded for the premises file.
