What is specific about Aldawadmi for water tank waterproofing

The centre of Aldawadmi sits about 976 m above sea level (SRTM open elevation data). Main roads in or near Aldawadmi: King Abdulaziz Road, Dawadmi Bujadiyah Road.

Team note on Aldawadmi: 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..

Restaurants in Aldawadmi most often run into leaking water tanks because the tanks are used hard and refilled often, and small cracks or failed old coatings let water seep into the walls and slab. The first sign is usually damp patches on the outside of the tank wall, a drop in pressure, or a musty smell in the back-of-house area. Because a commercial kitchen depends on a steady supply for washing, cooking and cleaning, a leak is not just a repair cost but a daily disruption. Catching it early keeps the job smaller and the downtime shorter.

The location changes the approach. The centre of Aldawadmi sits about 976 m above sea level (SRTM open elevation data), which means the site is on a raised plateau rather than low ground, so surface runoff tends to move quickly and water is not usually pooling against the tank from outside. For a restaurant, this means the main work is inside the tank and on its joints rather than in drainage. Crack injection is priced at SAR 40–120 per metre, and an internal tank coating at SAR 25–60 per m², so a typical plan for an older tank may combine repairing visible cracks first and then re-coating the inner surface. Where the roof of the tank or the building is exposed, liquid roof waterproofing at SAR 8–25 per m² or a bitumen membrane at SAR 15–35 per m² may be considered, while spray foam at SAR 20–45 per m² or XPS boards at SAR 12–30 per m² suit insulation-led jobs.

Before booking a visit, ask for the tank's capacity and age, when it was last cleaned and whether any previous coating has been applied. Ask which work is priced per m² and which per metre so you can compare quotes on the same basis, and check whether the quote covers cleaning and drying the tank before the coating goes on. Find out how long the restaurant can run on stored water during the work and whether the crew can schedule around your busiest hours. Finally, request a written breakdown showing which materials are used, since epoxy coating at SAR 35–90 per m² and basement or bathroom work at other rates should not be mixed into a single tank estimate.

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