Water tank sealing in Al Husayniyah Makkah
Al Husayniyah is a mixed zone between old farmland and new housing, and tanks here face dual challenges. High humidity from the wadi and nearby groundwater cause leaks from floor and walls. Unstable soil around new buildings adds stress to old tanks.
-
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.
-
Ground and roof tanks
Villas, apartment blocks and premises that need a written record of each visit.
Why the job is different in Al Husayniyah
Tanks here face high humidity from Wadi Uranah and nearby wet soil, causing hydrostatic pressure from outside the tank. The method is set out in full on what Water tank sealing involves.
Wadi humidity and groundwater pressure
Wadi Uranah crosses the district and raises groundwater level. Buried or semi-buried tanks face water pressure from outside year-round.
New housing on old farmland
The district shifted rapidly from farmland to housing schemes. New foundations and modern tanks were laid on unstable soil with naturally high moisture retention.
Mix of old and new tanks
Old farm-era tanks sit beside new building tanks. The old ones were not designed to withstand high humidity and hydrostatic pressure.
Al Husayniyah on the map
Al Husayniyah sits about 3 km from Al Awali and about 6 km from Al Naseem.
Open in Google MapsWhat we read before any material is opened
A mixed zone of old farmland and orchards converted into housing schemes, stretching behind Al Awali towards Jabal Kasab and Wadi Malakan on the Taif Al Hada road.
Cracking in the wall
Floor leaks are the primary cause due to high groundwater pressure from below.
The floor to wall joint
Wall cracks on lower sections and corners appear because groundwater presses from all sides.
The condition of the old lining
Pipe openings are a common leak source because groundwater finds the weakest seal point.
Sediment and scale
High internal humidity promotes algae and bacterial growth because ventilation is poor and light limited.
The pipe entries
Salt deposits from wet soil accumulate on walls and floors and damage new coating adhesion.
The hatch and the vent
Pressure from groundwater cracks the roof if the tank is not properly supported from below.
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 Al Husayniyah
Mixed district: shops at street level with homes above them
The mixed agricultural-residential character means high humidity and unstable soil. Tanks need strong sealing against hydrostatic pressure and an effective drainage system around the building.
Questions about this district
Why does my tank leak from the floor even though the cement is new?
Groundwater from the wadi creates pressure on the floor from outside. This pressure splits small cracks and causes leaks.
Is sealing the walls alone enough or must I seal the floor too?
The floor is most vulnerable because groundwater presses on it constantly. Both floor and walls must be sealed and drainage around the tank improved.
Does Al Husayniyah's wet soil need special preparation before sealing?
Yes, we must improve drainage around the tank first. If groundwater is very high, we may need a sump well or drain system.
Will groundwater affect the seal's durability after we finish?
Yes. If hydrostatic pressure persists, the seal may fail over time. Good drainage around the tank is essential.
How do we tell internal leaks from leaks caused by external pressure?
External pressure leaks start at the floor and lower corners. We measure hydrostatic pressure by drilling test wells around the tank to check groundwater level.
Are new buildings in Al Husayniyah better protected from moisture?
Newer buildings are better but still need professional sealing and drainage. Older tanks in the area face greater risk.
How much does water tank sealing in Al Husayniyah 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 Al Husayniyah.
