Do I really need periodic checks if my floors and roof look fine? That is the question many property owners in Alkharj ask, and the honest answer is that surfaces often hide early wear. The centre of Alkharj sits about 439 m above sea level, a setting that brings its own exposure to sun and dust, so coatings and membranes benefit from being looked at before small faults become costly repairs. Preventive work is usually priced per square metre, and the reference ranges help you plan: epoxy coating runs SAR 35–90 per m², liquid roof waterproofing SAR 8–25 per m², and crack injection SAR 40–120 per metre.
A periodic inspection follows a clear sequence. The technician first walks the epoxy-coated floors, tank interiors and wet areas, looking for hairline cracks, lifted edges, discolouration and places where the surface has lost its gloss. Next comes the roof and any bitumen membrane, checking for blistering, split seams and ponding water. Basements and bathrooms are then tested for damp patches and staining along joints. Where a crack is found, it is measured in metres so the repair can be scoped properly, and the findings are noted against the area and the material already in place. The result is a short written list of what is sound, what needs attention soon and what can wait, so that spending follows real need rather than guesswork.
Before the visit, clear access to the areas you want checked, especially basement corners, bathroom walls and the roof hatch, and move stored items away from the walls. Tell the technician which surfaces were treated before and when, and bring any earlier records or invoices you hold. If a tank is part of the scope, note its size and whether it is in use, since it must be emptied and dried for an internal check. Having this information ready lets the inspection cover more ground in one visit and gives you a clearer picture of the work ahead.
Preventive checks follow a written schedule instead of waiting for a fault.
When do you need epoxy coating & waterproofing?
The following signs are worth checking before they grow:
- A tank that needs an easy-to-clean surface
- A warehouse floor that is wearing away
- Oil stains on a floor
Where the problem usually comes from
- Insufficient preparation.
- A damp surface that ruins adhesion — we check this before anything else.
Tools and methods, and when we use them
| Tool | What it finds | When we use it in Alkharj |
|---|---|---|
| Fill test with level monitoring | Whether a tank coating holds after the work | Limits: takes time to monitor the level |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Thickness measurement at spread-out points | Whether the thickness in the quote was achieved | Limits: for foam and liquid-applied layers |
The steps in order
- Surface moisture reading: Epoxy is applied only when the substrate is dry enough.
- Careful preparation: Grinding and cleaning for adhesion.
- Layers: Primer and body coats as specified.
- Inspection: Thickness and curing are checked.

Questions from Alkharj
Does an underground tank require waterproofing even if it is new?
Yes, concrete is naturally porous, which can lead to leaks or groundwater seepage. Applying epoxy or cementitious insulation from the start maintains water quality and protects the structure from corrosion.
Do you need to evacuate the building during renovation work?
It depends on the type and scope of the work. Surface work such as plastering and painting usually does not require evacuation, while partial or full evacuation may be advised in cases of structural reinforcement, and the contractor determines this after inspection.
What is the first step of epoxy coating & waterproofing (preventive periodic check)?
We start with surface moisture reading (epoxy is applied only when the substrate is dry enough), then careful preparation (grinding and cleaning for adhesion).
How much does epoxy coating & waterproofing cost in Alkharj?
From our published price list: Epoxy coating (per m²) SAR 35–90 per m². Quantities are confirmed at the inspection.
What do I get at the end?

Planning the visit in Alkharj
- Have access ready to the water meter, the tank hatches, the roof and the main valve; in apartment buildings the roof keys are often with the building guard (haris).
- Prices are in Saudi riyals (SAR); the final price is confirmed after the inspection, before any work starts.
- Keep photos of the problem and of any earlier repairs — they help the technician compare before and after.
- If you rent, tell your landlord or building management before the visit and agree in writing who pays; the written report can be shared with them.
