Water tank sealing in Hatim Makkah
Hatim is a rural area at the far eastern end with farms, orchards and unbuilt land. Water from deep wells and wadi channels supplies irrigation. Farm tanks suffer from severe salt from deep wells and groundwater plus root pressure from trees and seasonal expansion stress.

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.

Ground and roof tanks
Villas, apartment blocks and premises that need a written record of each visit.
Why the job is different in Hatim
Low-density area with water from very deep wells rich in salts, heavy minerals and sulphates. The method is set out in full on our Water tank sealing service.
Deep well water is very saline
Wells in Hatim are very deep and water carries high concentrations of salt, iron and sulphates. Unsealed tanks corrode internally quickly and salt crystals deposit on floors.
Tree roots pressure tanks from outside
Farms and orchards around tanks contain large trees whose roots grow toward tanks. Roots may penetrate small cracks or pressure the tank causing new fractures.
Seasonal swings cause large concrete stress
Temperature in Hatim swings day to night and summer to winter. Concrete expands and contracts under constant water pressure and mineral load, cracking walls.
Hatim on the map
Hatim sits about 2 km from Thaniyah and about 3 km from Barakah.
Open in Google MapsWhat we read before any material is opened
Agricultural land and unbuilt schemes at the far eastern end on both sides of the Makkah to Taif expressway near Al Hamidah hamlet and the bed of Wadi Al Sharai. Farms and orchards line the wadi, Jabal Laban rises to the east and rural houses are widely spaced.
Cracking in the wall
Concrete surface carries salt deposits and crystals from very saline deep well water.
The floor to wall joint
Floor-to-wall joints contain cracks from constant pressure and salt and mineral buildup.
The condition of the old lining
Inlet and outlet pipes may be blocked by salt, sulphate and iron deposits.
Sediment and scale
High moisture from groundwater and continuous irrigation increases tank pressure.
The pipe entries
Tank foundations may be under stress from tree roots and seasonal expansion-contraction.
The hatch and the vent
Water leaks may appear from cracks or joints or from tank bottom when pressure from salts is high.
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 Hatim
Rural area: farms, open ground and scattered homes
A rural area means tanks may be large and under high pressure from deep wells. Saline water, roots and seasonal swings all stress the tank, so sealing must be thick and made from materials resistant to salts and heavy minerals.
Questions about this district
Why is deep well water in Hatim so saline?
Wells are very deep and water passes through deep layers rich in salts and sulphates. Deeper wells mean higher salinity.
Are tree roots dangerous to a sealed tank?
Strong sealing stops root penetration but roots may pressure the tank from outside and cause concrete cracks.
Is water desalination better than tank sealing?
Desalination is very costly. Tank sealing is cheaper because it protects concrete from corrosion and extends tank life.
How often should a farm tank need inspection and repair?
Twice yearly inspection is important because heavy salts accumulate quickly. Deposits and crystals may block pipes.
Are heavy minerals in the water dangerous to the tank?
Yes. Minerals like iron and sulphates cause rapid corrosion in concrete and metal. Sealing protects against direct contact.
Can the same sealing be used for large and small tanks in Hatim?
Yes. The same sealing materials work for all sizes. Large tanks may need thicker sealing due to high water pressure.
How much does water tank sealing in Hatim 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 Hatim.
