Does altitude affect how a school's floors and balconies need to be waterproofed in Khamis Mushait? The centre of Khamis Mushait sits about 1998 m above sea level (SRTM open elevation data), and that elevation is one reason the town's weather patterns matter when planning protection for school buildings. Schools here often have large flat roofs, open walkways and balconies that carry rainwater in short, intense bursts. For these surfaces, the usual options are liquid roof waterproofing at SAR 10–25 per m², bitumen membrane at SAR 15–35 per m², and spray foam at SAR 20–45 per m². Each has a different cost and a different suitability for foot traffic and drainage, so the right choice depends on the specific floor or balcony in question.
Our inspection begins with a walk over every floor and balcony surface to note ponding, cracked screeds, failed sealant at joins, and any stains on the ceiling below. Where cracks are present, the technician measures their length, since crack injection is priced per metre at SAR 40–115 per m. Drainage outlets, upstands at walls, and the condition of existing coatings are checked and recorded. Where a surface is already protected by an older layer, the inspector looks for blistering or lifting that would prevent a new layer from bonding properly. The findings are then written up as a site note that lists each area, the recommended method, and a cost range based on measured square metres, so the school's facilities team can compare options before any work is approved.
Before the visit, please gather the building plans or any drawings showing the floor and balcony layouts, along with records of previous repairs or waterproofing work carried out on those areas. Note which spaces are used by students during break times and which are kept clear, since this affects how and when work can be scheduled. Clear access to roof hatches, balcony doors and any locked storerooms will save time on the day. It also helps to mark problem spots you have already seen, such as damp patches, peeling paint or areas where water collects after rain. With this information ready, the inspection can focus on what matters most and produce a clear plan for your school.
For schools, the larger jobs are planned for weekends and holidays.

Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Flood test | Whether the waterproofing holds before it is covered | Limits: for roofs with drains and wet areas before tiling |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
How the work is done, step by step
- Checking the falls: Where water collects and where it should go.
- Details: Thresholds, drains and upstands.
- Waterproofing: The layer is applied and protected.
- Flood test: Tested before the finish goes on.

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.
