Water tank sealing in Hunayn Makkah
Hunayn lies at the north-eastern tip of Al Sharai where Wadi Hunayn meets the Taif road. The village depends on natural springs and groundwater to water palm orchards and scattered farms, and tanks here face constant pressure from hard, mineral-rich water. Sealing requires understanding how groundwater composition and desert heat affect cement linings.

Potable-rated materials
Linings and disinfectants cleared for drinking water tanks, not general-purpose products.
-
You get the downtime first
How many hours the tank is out of service, told before we start rather than after we finish.
-
A first-draw flush
We run the first draw off after refilling, and the tank is not handed back until the water runs clear.

Why the job is different in Hunayn
Tanks in Hunayn serve scattered farms and rural homes, and the groundwater carries high concentrations of salts and minerals that accelerate cement breakdown. The method is set out in full on Water tank sealing in detail.
Hard, mineral-rich groundwater
Springs and boreholes in Hunayn yield water rich in calcium, sodium and dissolved minerals. These deposit on tank walls and penetrate fine cracks over time.
Exposed tanks in desert conditions
Most Hunayn tanks stand open to sun and seasonal winds, enduring daily expansion and contraction. Temperature swings between night and day cause rapid cracking of the cement lining.
Pump outlets and farm pipe networks
Tanks here connect to complex irrigation systems with pumps and buried pipes feeding orchards. Pipe joints and entry points are the weakest spots and first to leak.
Hunayn on the map
Hunayn sits about 4 km from Barakah and about 6.5 km from Hatim.

Cracking in the wall
Groundwater in Hunayn carries high concentrations of salts, calcium and sodium that deposit on internal surfaces.
The floor to wall joint
Leakage begins at pipe joints and floor-to-wall corners, as these zones bear the greatest water pressure.
The condition of the old lining
Fine cracks start from daily temperature swings, especially in old, weak cement.
Sediment and scale
Exposed tanks absorb direct sun, causing cement and lining expansion and rapid cracking.
The pipe entries
Poor ventilation around the tank leaves moisture in the base and floor, weakening the bond between old cement and new lining.
The hatch and the vent
Bacteria and algae grow on the internal surface of a weakened tank, affecting water colour and safety.
How we work
-
1
Inspect with the tank empty
We drain it and read the surface dry: whether the water leaves through a crack, a joint or a pipe collar, and what the outer face of the wall and the ceiling below are telling us. A level test with the valves closed separates a leaking tank from leaking pipework.
-
2
Clean and prepare the substrate
Sediment out, a high pressure wash, the loose old lining and the weak surface layer of the concrete taken back, then dried. The material grips sound substrate and nothing else.
-
3
Make the cracks and joints good
Cracks are chased out and filled with a repair mortar, a cove is formed where the floor meets the wall, and every pipe collar is treated on its own.
-
4
Lining, fill test, sterilisation
Successive coats, each run across the one beneath it, on the face the water touches. Then a full cure, a fill with the level watched, and sterilisation with the first fill run to waste before the tank returns to use.
What water tank sealing includes
-
Finding where the water leaves
Carried out drained and dry: cracks, joints, pipe collars and the outer face of the wall.
-
Draining and sediment removal
The last of the water and the settled layer on the floor come out, because a lining does not stick over sediment.
-
Cracks and joints made good
The crack opened and filled, a cove formed at the floor to wall junction, and each pipe entry worked separately.
-
Lining coats on the water face
More than one coat, each crossing the one below, in material made for drinking water tanks rather than roof waterproofing.
-
Curing, fill test and sterilisation
The material is left to cure, the tank is filled and the level watched, then sterilised and the first fill run to waste. How long the cure takes follows the material and the weather, and we tell you before the date so you can plan around the supply.
-
A follow-up level check
We come back once it is in service to read the level and check the outer face, because any remaining loss shows up then rather than on the day of the work.
The character of Hunayn
Rural area: farms, open ground and scattered homes
A rural setting means tanks serve scattered farms and homes rather than a central supply. Continuous pumping of mineral-rich water, intense heat and daily temperature extremes mean sealing is more severe than in regular residential areas, and the lining must resist both salt deposition and thermal stress.
Questions about this district
Why do Hunayn tanks leak faster than tanks elsewhere?
The groundwater holds high salt and mineral content that corrodes cement quickly. Intense heat and daily temperature swings cause accelerated cracking.
Does leakage from the tank affect water quality?
Yes. Leaks draw bacteria, sand and soil particles from surrounding earth. Water becomes cloudy and may pose health risks.
Is a new lining enough or must we repair cracks first?
Cracks and base faults must be fixed first. The lining needs sound substrate or it will crack as fast as before.
Does hard groundwater shorten the life of a new lining?
Yes. Mineral salts deposit on the lining and weaken it from within. Regular cleaning and maintenance extend lining life.
How do we seal multiple pipe entries safely?
Each entry is sealed with flexible materials that tolerate thermal movement. Pipe joints are where water first escapes.
Can an open tank in the desert provide safe drinking water?
An exposed tank allows dust, insects and bacteria into the water. Covering or externally sealing the tank protects water better.
How much does water tank sealing in Hunayn cost?
It is set after the inspection, because the price follows the type of infestation, the size of the space, how far it has spread and the number of visits it needs. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Hunayn.
