What is specific about Abu Arish for water tank waterproofing

The centre of Abu Arish sits about 67 m above sea level (SRTM open elevation data). Team note on Abu Arish: 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..

Do rest houses and farms in Abu Arish really need their water tanks waterproofed, or can a tank simply be filled and left alone? The honest answer is that a tank which leaks loses water every day it goes unnoticed, and a tank that is coated internally keeps its water cleaner and its structure sounder. Abu Arish sits about 67 m above sea level, so the centre of town is not a low-lying basin where water collects after rain, which means owners here are usually dealing with tanks that have simply aged, cracked or been poorly sealed at the start. Tank internal coating is priced at SAR 25–60 per m², and that is the figure to budget against when you compare quotes for a tank that is already showing wear.

The inspection begins with a walk around the outside of the tank and then a close look at the inside once it is emptied and dried. The technician checks for cracks, flaking old coatings, staining along seams and any damp patch on the surrounding floor or wall. Where a crack is found, the cost is usually measured in metres, and crack injection is quoted at SAR 40–120 per metre, so the length of every visible crack matters. The roof and any bitumen or liquid roof layer above the tank are checked too, since liquid roof waterproofing at SAR 8–25 per m² and bitumen membrane at SAR 15–35 per m² are the usual options where water enters from above rather than through the tank walls.

Before the visit, empty the tank as far as practical and let the inside dry for a day or two, because moisture stops coatings from bonding. Clear the access hatch and the area around the tank so the inspector can measure and photograph freely. Note the tank's approximate size and any past repairs, and mention whether you have noticed a drop in water level or a damp patch nearby. Having these details ready lets the inspection move straight to the work and gives you a clearer quote to compare.

Rest houses and farms often have long buried lines, tanks and irrigation that need separate tests.
