Does a restaurant in Muhayil Aseer really need its water tank waterproofed, and what does it cost? The short answer is yes, and the cost depends on the work involved. The centre of Muhayil Aseer sits about 455 m above sea level, and the tanks serving busy kitchens and dining rooms take constant use that can wear down their linings over time. Tank internal coating is priced at SAR 25–60 per m², which is the main line item for this job. Where the tank or its surrounding area also needs sealing, epoxy coating runs at SAR 35–90 per m², and crack injection is charged at SAR 40–120 per metre for cracks that have opened up along the walls.

Our inspection starts with a walk around the tank and its connections to look for active leaks, staining, and cracks. The technician measures the surfaces that need treatment so the quote reflects real areas rather than estimates. Cracks are marked and their lengths recorded, because injection is priced per metre. The tank is then checked for loose material and residue that would stop a coating from bonding properly. If the roof or the plant area above the tank is also involved, the inspector notes the condition of that surface so it can be quoted separately, with liquid roof waterproofing at SAR 8–25 per m² or bitumen membrane at SAR 15–35 per m² as options. Each finding is explained before any work is agreed, so you know exactly what is being recommended and why.

To make the visit efficient, clear access to the tank and its surroundings before the technician arrives. Tell the restaurant team when the tank will be out of service, since the inside of the tank must be emptied and dried before coating. Have a record of when the tank was last cleaned and any previous repairs, as this helps the inspector judge how the lining has aged. Note any places where water has been seen, including dates and rough locations, and mark the cracks you already know about. Confirm who will sign off the quote so decisions are not delayed, and keep the kitchen's water supply plan ready for the days the tank is offline.

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