Does a school water tank in Khamis Mushait really need waterproofing, and what does it cost? Tanks here sit at high altitude, and the centre of Khamis Mushait is about 1998 m above sea level, so buildings deal with strong sun, sharp temperature swings and wind-driven rain. Those conditions stress tank walls and joints, which is why a leaking tank can quietly damage a school's supply and its ceilings below. Tank internal coating is typically priced at SAR 25–55 per m², and epoxy coating at SAR 35–85 per m², so the right system depends on the tank's condition and the surface being treated. Crack injection, at SAR 40–115 per m, is often used where a single defect is the problem rather than the whole surface.
The inspection starts with a walk around the tank and the roof area it sits on, looking for staining, efflorescence, damp patches and cracks at wall and floor joints. The technician measures the affected surfaces so the quote reflects the real area, separating internal tank work from external roof work such as liquid roof waterproofing at SAR 10–25 per m² or bitumen membrane at SAR 15–35 per m². Cracks are marked and their length recorded in metres, because injection is priced per linear metre. Where water has been seeping, the inspector checks the source, since a surface coating alone will not fix a leak coming through a failed joint. The findings are then written up so the school can compare options before any work is approved.
Before the visit, the school should arrange access to the tank, the roof and the plant room, and confirm that the water supply can be shut down or the tank emptied for inspection. Gather any previous maintenance records, notes on when leaks were first noticed, and photos of stains or damp areas, as these help the inspector focus on likely problem spots. Let the facilities team know the expected visit window so classes and water use are not disrupted. Having these details ready keeps the inspection short and makes the resulting quote easier to check against the work that is actually needed.
For schools, the larger jobs are planned for weekends and holidays.

Questions from Khamis Mushait
Do I need thermal insulation in Khamis Mushait despite its moderate climate?
Yes, thermal insulation keeps the home warm in winter, reduces the need for heating, and limits the effect of day-to-night temperature fluctuations.
Do I need an engineer before starting renovation?
It is advisable when there are deep cracks, tilting, or sinking in the floors, because these signs may indicate a structural problem. In simple cases such as peeling paint or limited dampness, an inspection by a specialized contractor may be sufficient.
