Water tank waterproofing in Alqunfudhah: the local context

Team note on Alqunfudhah: Kashf teams serve this city and its nearby districts with the same documented inspection standard: device-based leak detection without demolition, a written report, and a clear scope before any work begins.. The centre of Alqunfudhah sits about 7 m above sea level (SRTM open elevation data).

Alqunfudhah is about 0.4 km from the sea coast (OpenStreetMap).

Do you need to waterproof your water tank before summer or the rains arrive in Alqunfudhah? The centre of Alqunfudhah sits about 7 m above sea level, and the town is about 0.4 km from the sea coast. That closeness to the coast means the air is humid and salty, which can speed up wear on exposed concrete and metal, so tanks here deserve regular attention. Tank internal coating is priced at SAR 25–60 per m², and epoxy coating at SAR 35–90 per m², so the right option depends on the condition of the surface and how much area needs work.

The inspection starts with a close look at the tank walls, floor and lid for cracks, flaking paint, and damp patches on the outside. Crack injection, priced at SAR 40–120 per metre, is often the first step where hairline cracks are found, and a technician will mark each crack and measure its length before quoting. Spray foam, at SAR 20–45 per m², and liquid roof waterproofing, at SAR 8–25 per m², may be relevant where the tank sits on or near a roof. The inspector will check each area, note which method suits it, and explain the options in plain terms before any work begins.

Before the visit, empty the tank as far as practical and clear the area around it so the surfaces can be reached easily. Note any past leaks, water staining, or changes in taste or colour, and have your property papers or access details ready. Ask the team to walk you through the findings and the price range for each method, so you can compare the work against your budget before summer heat or the rainy season arrives.

Checks before summer and before the rain season catch problems while they are still small.
