Water tank waterproofing in Al Yrmwk: the local context

The centre of Al Yrmwk is at 24.8085, 46.7835, about 15.2 km from the centre of Riyadh, with an approximate radius of 3.2 km. The approximate area shown on the map is centred here.

The centre of Al Yrmwk sits about 598 m above sea level (SRTM open elevation data).

Picture a rest house or farm owner in Al Yrmwk who has a water tank on the roof or beside the main building. Over time, the tank starts to show damp patches, a faint smell, or small leaks at the seams and joints. Because the property is used mainly on weekends and in holiday periods, the problem can go unnoticed until water is lost or the walls below begin to stain. Many owners want to fix it once, properly, rather than patching it every season.

Al Yrmwk sits at about 24.8085, 46.7835, roughly 15.2 km from the centre of Riyadh, within an approximate radius of 3.2 km. Its centre is about 598 m above sea level. For an owner, this means the site is close enough to the city for easy access by contractors, yet the property may still be spread out over open ground where the tank and roof are exposed to strong sun and heat. Those conditions break down coatings and sealants faster, so the choice of material matters. The inside of the tank needs a coating suited to stored water, while the roof and any connected surfaces need protection against heat and movement. Planning the work around these local conditions helps the repair last.

A practical approach starts with a clear inspection. First, empty the tank and check the walls, floor and joints for cracks, flaking, or soft patches. Second, mark every crack that needs crack injection, which is priced per metre, so measuring the total length early gives a realistic picture of the work. Third, decide on the tank lining, where internal coating is priced per m², and confirm the surface is clean and dry before application. Fourth, treat the roof separately, choosing between liquid roof waterproofing, bitumen membrane, or XPS boards for insulation under the finish. Fifth, let each layer cure fully before refilling and testing. Finally, refill the tank slowly and check for leaks over several days, keeping a short written record so future maintenance is easier to plan.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.
