Many property owners in Muhayil Aseer ask whether a water tank is worth waterproofing before they buy or rent a home, and the honest answer depends on the tank's condition and how the rest of the building is sealed. The centre of Muhayil Aseer sits about 455 m above sea level (SRTM open elevation data), so the town's climate and local water supply arrangements matter when judging how a tank has been used. Tank internal coating is priced at SAR 25–60 per m², which gives a useful baseline when a seller's asking price leaves room for a repair. Our guidance is to treat the tank as part of the wider water-proofing picture, not a standalone item.

Inspection starts with a dry look and then a wet one. Check the tank's internal surface for cracks, flaking, and staining, and note where the walls meet the floor, since those joints are the most common leak points. Look at the outside too, along the roof and any rooftop liquid roof waterproofing, which is typically priced at SAR 8–25 per m². Where cracks are visible, crack injection is quoted per metre at SAR 40–120 per m, so measure the length of any defects you find. Record which areas need coating, which need crack repair, and which seem sound, so you can compare quotes on the same basis. If the building has a basement, check it separately, because basement waterproofing ranges from SAR 50–150 per m².

Before the visit, gather what you already have: the building's age, any previous repair records, the tank's dimensions, and photographs of the tank and roof taken on a dry day. Ask the seller or landlord whether the tank has ever been drained and cleaned, and when. Bring a torch, a tape measure, and a notebook, and plan to inspect when the tank is empty so you can see every surface. Finally, ask the service provider to explain their method in writing, including whether they will use epoxy coating at SAR 35–90 per m² or a different system, so you can judge the proposal against the facts before you commit.

Before buying or taking over a property, an inspection gives you findings in writing before you sign.
