Does a water tank in Al Dyra, Riyadh need waterproofing, and what does the work typically cost? Al Dyra is a district in the south of Riyadh, with its centre at 24.6323, 46.7108, about 9.7 km from the centre of Riyadh, with an approximate radius of 3 km. Its neighbourhood includes historic buildings, and the centre sits about 589 m above sea level. The nearest wadi channel is about 2.8 km from the centre, which is worth knowing if your tank sits on a site that collects runoff. For the tank itself, the relevant published rate is tank internal coating at SAR 25–65 per m², so the cost depends on the surface area that needs treatment.

Before any quote is agreed, a proper inspection is the sensible first step. The inspector will walk the tank and note the areas where waterproofing has failed, looking at the walls, floor and joints. Where cracks are present, crack injection is priced at SAR 40–125 per metre, and the inspector will measure the length of each crack so the work can be costed accurately. The inspector also checks the surfaces to decide whether an epoxy coating (SAR 35–95 per m²) or another system suits the condition of the concrete. If the tank sits in a basement or lower-level area, basement waterproofing is priced at SAR 55–160 per m², and the inspector will note whether that applies. Each finding is recorded so you receive a clear breakdown of what is needed and why.

To make the visit efficient, prepare the tank's access in advance. Clear the area around the tank and the access hatch so the inspector can reach the walls and floor safely. Note any leaks you have seen, the dates they started, and where water has appeared on walls or ceilings. If you have earlier plans, invoices or records of previous repairs, have them ready, as they help the inspector understand what has already been treated. Make sure the water supply to the tank can be shut off during the visit, and let the inspector know if the tank is in regular use so that the work can be planned around it.
