Epoxy coating & waterproofing in Alkharj: before summer & rain season
In short: Epoxy coating & waterproofing (before summer & rain season) in Alkharj starts with the moisture meter for ceilings and walls, then the thickness measurement at spread-out points, before anything is opened. The centre of Alkharj sits about 439 m above sea level (SRTM open elevation data). Published price: Epoxy coating (per m²), SAR 35–90 per m²; anything else is quoted after the inspection.
Before we start: what we know about Alkharj

Epoxy coating and waterproofing in Alkharj most often comes up for homes and small commercial buildings that have hit one of two problems: floors that stay damp or break down under heat, or roofs and water tanks that leak once the rains arrive. Many owners only notice the trouble after a crack has opened or a patch of coating has peeled, which is why a planned job before the hot season or the wet season is usually cheaper and less disruptive than a rushed repair.
Alkharj sits at about 439 m above sea level, which means it is not a coastal humidity zone but still gets sharp day-night temperature swings and heavy short bursts of rain. Those swings make surfaces expand and contract, so a coating that is applied to a cracked or poorly prepared base will fail first at the joints. For that reason the approach here starts with the substrate: cracks are injected before the coating goes on, and roofs and tanks are checked for movement. Options are matched to the surface and budget. Typical rates to compare include basement waterproofing at SAR 50–150 per m², bathroom waterproofing at SAR 15–40 per m², epoxy coating at SAR 35–90 per m², spray foam at SAR 20–45 per m², crack injection at SAR 40–120 per m, liquid roof waterproofing at SAR 8–25 per m², bitumen membrane at SAR 15–35 per m², tank internal coating at SAR 25–60 per m², and XPS boards at SAR 12–30 per m².
Before the visit, ask the provider which surface they propose to treat and why, and whether they will inspect and record existing cracks before quoting. Ask what prep work is included, how the price is stated per square metre or per metre of crack, and whether the quote covers materials, labour and cleaning of debris. Confirm the timing so the work avoids the hottest part of the day and any rain forecast, and ask how long the area must stay closed before use. A clear written scope, measured areas and a plain explanation of the chosen system will tell you more than any sales claim.
Checks before summer and before the rain season catch problems while they are still small.
When do you need epoxy coating & waterproofing?
The following signs are worth checking before they grow:
- Oil stains on a floor
- A warehouse floor that is wearing away
- A tank that needs an easy-to-clean surface
The most common causes
- A damp surface that ruins adhesion — we check this before anything else.
- A common cause: insufficient preparation.
Tools we use in Alkharj
| Tool | What it finds | When we use it in Alkharj |
|---|---|---|
| Thickness measurement at spread-out points | Whether the thickness in the quote was achieved | Limits: for foam and liquid-applied layers |
| Moisture meter for ceilings and walls | Where water is entering now, from inside | Limits: measures the effect, not the water path |
| Fill test with level monitoring | Whether a tank coating holds after the work | Limits: takes time to monitor the level |
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.

Short answers for 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.
Where does epoxy coating & waterproofing (before summer & rain season) start in Alkharj?
We start with surface moisture reading (epoxy is applied only when the substrate is dry enough), then careful preparation (grinding and cleaning for adhesion).
