Water tank waterproofing in Alqurayyat: emergency

Prepared by the technical team · editorial review · last updated 13 November 2026 · Sources

Before we start: what we know about Alqurayyat

The centre of Alqurayyat sits about 497 m above sea level (SRTM open elevation data). Team note on Alqurayyat: 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..

My water tank is leaking and I need it fixed quickly. Can a waterproofing team in Alqurayyat respond in an emergency, and what does it cost? Alqurayyat sits at about 497 m above sea level, and the work covers the whole tank, from the inside coating to the external seals, so a proper inspection comes first. For tank internal coating, expect SAR 25–60 per m², and for crack injection, which is often the fix for a leaking seam or wall, expect SAR 40–120 per metre. If the leak is coming through the roof or the tank cover, liquid roof waterproofing runs SAR 8–25 per m², while a bitumen membrane runs SAR 15–35 per m². Prices depend on the area and the method, so the team will confirm the final figure after they see the tank.

Once the crew arrives, they start by finding where the water is actually getting in. They check the tank walls, base, joints and any visible cracks, and they look at the roof and the supply connections. Where a crack is active, they mark its length so the injection can be measured in metres. They then check the surfaces that will receive the coating, because epoxy and tank internal coatings only bond to a clean, sound base. Once the source is clear, they explain which system suits the damage and give you a quote based on the measured area or length. No work starts until you have agreed to the scope and the price.

To help the visit go quickly, prepare a few things before the team arrives. Note when you first saw the leak and whether it is worse after the tank fills, since that points to the source. Clear access to the tank, its lid and the roof, and switch off or isolate the supply pump so the water level stays steady during the check. If you have any earlier waterproofing records or photos of the damage, have them ready. Finally, plan for the tank to be drained or partly emptied during the repair, and arrange temporary water for your household so the work can proceed without delay.

If water is flowing, close the main valve first, then call or message with photos.
