Water tank sealing in Al Hindawiyah Makkah
Al Hindawiyah is an old, densely built district on the west side of Makkah with low apartment buildings, small flats and shops packed into every corner. Tanks here are very old, built with the original buildings decades ago. Soil beneath the district is salt-rich and damp from the age of construction and poor drainage, causing oxidation and weakening of the tank body itself.
-
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 Hindawiyah
Residential buildings here are very old, built more than fifty years ago on uneven land. The fabric is informal, foundations are weak and the old drainage system has not been repaired since the original construction. The method is set out in full on Water tank sealing in detail.
Very old tanks and advanced oxidation
Tanks here were built with the original buildings and are over fifty years old. Metal surfaces outside are oxidised from moisture and salt in soil and air. The tank walls themselves may be thin and have weakened over decades.
Poor drainage and permanent dampness
Old quarters have very poor drainage and water pools beneath foundations. Tanks absorb moisture and salt from the soil and standing water. Oxidation and corrosion happen much faster than in dry areas.
Popular markets and very high population density
The quarters contain dense popular markets, shops and residential buildings packed tightly together. Water consumption is very high and tanks fill and empty all day. Mechanical pressure on the tank is constant and corrosion accelerates.
The character of Al Hindawiyah
Commercial area: offices, showrooms and small stores
An old, densely built commercial district means tanks are old and weak and drainage is very poor. Salt and moisture in soil cause accelerated corrosion, so sealing must be very strong and drainage repair around the tank is essential before final sealing.
What we read before any material is opened
An old, densely built residential and commercial district on the west side of Makkah, bordered by Al Mansour to the east, Al Khalidiyah to the south, Al Rusayfah and Al Nuzha to the west and Al Utaibiyah to the north. Low apartment blocks, small flats, dense popular markets and unplanned construction.
Cracking in the wall
Tank surface inspection reveals advanced oxidation and rust on external and internal metal from constant moisture and salt.
The floor to wall joint
Corrosion and hole repair needs deep cleaning to remove rust and salt, and may require replacing weak sections of tank walls.
The condition of the old lining
Wall-to-floor joint corrodes from moisture and salt and may be very weak, needing comprehensive strengthening.
Sediment and scale
Pipe inlets and outlets may be a leak source from oxidation and weakness, and may need full replacement.
The pipe entries
Interior lining must be very strong and fully moisture-blocking because external dampness is intense.
The hatch and the vent
Tank sterilisation after sealing is essential because water may carry salt and minerals from the poor drainage.
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.
What is different about Al Misfalah Sub-Municipality
Al Misfalah sub municipality runs downhill from the south of the Grand Mosque through Al Misfalah, Kudai and Al Rawabi to Al Taqwa, Al Hindawiyah, Al Khalidiyah and Al Rusayfah at the third ring road. The northern end is old apartment blocks and pilgrim hotels with restaurants along Ibrahim Al Khalil Street and the huge coach parks at Kudai. The south and west are dense popular districts with countless small shops and unplanned hillside housing, some of it already cleared for redevelopment, giving way to orderly land grant schemes in Al Rusayfah beside the railway station.
Questions about this district
Why do old tanks in Al Hindawiyah corrode quickly?
Salt and moisture in the soil cause very rapid oxidation. Poor drainage means water stays beneath foundations and keeps the tank damp constantly.
Does oxidation come from outside or inside?
Both. The outside corrodes from moisture and salt, and inside may rust from salty water and mineral content.
Does treating an old tank save it or is replacement better?
If corrosion is surface level and tank walls thick, treatment saves it. If corrosion is very deep, replacement may be more economical.
Does the salt in soil come from the age of construction or elsewhere?
From the age of the land and its natural soil. Salt has accumulated over decades from drainage neglect.
Does sealing protect the tank from constant soil moisture?
Yes, good sealing cuts off contact between tank and external moisture. But drainage must be fixed first or the tank will dampen from inside.
Do we check foundations and drainage before sealing?
Yes, we check drainage around the tank and if poor we recommend drainage repair before final sealing.
How much does water tank sealing in Al Hindawiyah 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 Hindawiyah.
