Before we start: what we know about Almuzahimiyah
The centre of Almuzahimiyah sits about 889 m above sea level (SRTM open elevation data).
The facts given for this page do not name a specific city or area, so the opening paragraph has to rest on the building-level questions instead. Older residential buildings often carry an existing surface that may or may not be sound, and the first question homeowners should settle is whether that old layer must be removed before any new membrane goes on. Basement walls, bathroom and balcony floors, and water tanks each present different conditions, so the same product rarely fits all of them.
Because basement and foundation work sits below grade and is hard to inspect once covered, the team checks the existing substrate first: whether the surface can bond to a new layer, whether moisture is already rising, and whether the water tank has a suitable lining type. Spray foam, for example, is usually followed by a protective coat, so that requirement is confirmed before the work is scoped. Typical rates quoted for wall treatment in basements run from 50 to 150 riyals per square metre, while bathroom and balcony membranes run from 15 to 40 riyals per square metre and protective or reflective coatings from 10 to 30 riyals per square metre. These ranges help set expectations, but the final figure depends on what the surface actually needs.
Before the visit, gather the building's age, any previous repair records, and photos of damp patches or cracks, and note which spaces you use daily. Ask the team whether the old surface must come off, whether foam needs a protective layer in your case, and how to confirm the right lining for your water tank.
For a whole building, a survey of the shared systems comes before unit-by-unit work.
Signs worth paying attention to
If you notice one of these signs in Almuzahimiyah, it is a good moment to talk to the team:
- Salt marks at the bottom of the walls
- Damp basement walls
- Water seeping in after rain
The most common causes
- A high groundwater level — we check this before anything else.
- Rainwater draining towards the foundation — we check this before anything else.
- A common cause: cracks at construction joints.
Tools and methods, and when we use them
| Tool or method | What it measures | Why it is chosen here |
|---|---|---|
| Roof, falls and drains survey | Ponding areas and the condition of the old layer | Limits: shows the condition, not the material alone |
| Crack injection (polyurethane or epoxy) | Stopping active water through cracks | Limits: treats the crack, not the water source |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
The steps in order
- Finding the source: Groundwater, rain or a pipe — each needs a different treatment.
- Preparation: Surfaces are cleaned and opened where needed.
- Injection: Active cracks are injected.
- Waterproofing layers: The system is applied on the right side of the wall where possible.
- Follow-up: Readings are repeated after the treatment.

Questions from Almuzahimiyah
Does an old building need the old roof surface removed before insulation?
It depends on the condition of the roof surface and the type of insulation chosen. If the surface is sound, the insulation is applied over it after cleaning and treatment, and if it is damaged, the contractor may recommend repairing it or removing the damaged layers first.
Does spray foam need a protective coating after application?
Yes, an acrylic or similar protective coating is applied to shield the foam from sunlight. This coating is essential for maintaining insulation efficiency and extending its lifespan.
How do I know the right type of insulation for my water tank?
The type is determined by whether the tank is underground or overhead and the water usage. Drinking water tanks are usually insulated with safe materials like epoxy or specialized cement after contractor inspection.
