Water tank sealing in Al Muntazah Jeddah
Al Muntazah is a neighbourhood of relatively old apartment buildings east of Briman, densely packed with mid-rise buildings divided between workers and tenants. Tanks here are small rooftop units or built into walls, and rust and corrosion are common because routine maintenance is poor and buildings are aged.
-
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 Muntazah
Tanks in Al Muntazah are old and maintenance is neglected, and tenants report leaks late, causing repair delays and damage to accumulate. The method is set out in full on Water tank sealing in detail.
Small rooftop tanks exposed to corrosion
Older residential buildings in Al Muntazah have small rooftop tanks made from poor-grade materials. Wind, rain and sun cause rapid corrosion and rust eats through walls.
Tanks built into walls and structural corners
Some older buildings have tanks cast into walls or columns. Access is difficult and leaks may travel inside the building itself unseen.
Lack of maintenance and failed patch repairs from before
Tenants apply crude quick fixes: mud and ordinary cement patch cracks. These repairs fail quickly and leave the tank in poor condition.
The character of Al Muntazah
Apartment district: residential blocks, repeated floors and shared entrances
Al Muntazah is a simple residential district for workers and tenants, with small old neglected tanks. Lining must be robust and durable because repeated repairs are uneconomical and affect occupants.
What we read before any material is opened
A densely built Briman residential district bounded by Hada Al Sham Road to the north and Muawiyah Al Sulami Street to the west. Low-rise apartment buildings with shops on ground floors and narrow internal streets with worn surfaces.
Cracking in the wall
Leaks from roofs and corners are very common, and rust eats through walls from outside and inside both.
The floor to wall joint
Deep and extensive cracks signal structural corrosion and may need more than simple lining.
The condition of the old lining
High moisture around the tank signals continuous leak and water travels into the building fabric.
Sediment and scale
Bad odours and discoloured water point to bacterial and algal growth because the tank is old and maintenance poor.
The pipe entries
Previous crude repairs leave mud and cement patches, and their bond to substrate is very weak.
The hatch and the vent
Coastal environment nearby and salt in air speed corrosion, especially in metals and reinforcing steel.
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 Briman Sub-Municipality
Briman sub-municipality sits east of the Haramain expressway on Jeddah's north eastern edge. Its older quarters are planned grids of villas and walk-up flats, while the outer districts are new subdivisions still being built out. Seasonal wadis such as Wadi Umm Hablain and Wadi Al Asla cross the area, groundwater runs high in places, and drainage networks in the newer districts are incomplete, so soil around foundations stays damp. Vacant plots, live building sites and constant dust give crawling insects and rodents easy routes into homes, and the food outlets along the main arteries keep them supplied.
Questions about this district
Why do Al Muntazah tanks corrode faster than in other areas?
Tanks are old and original materials are weak and maintenance quality is very poor. Rain and salt wind from nearby sea speed corrosion.
Does a leak from a tank built into the wall damage the building structure itself?
Yes. Water may travel into the wall and masonry and cause internal moisture and steel corrosion. It can affect adjacent units below as well.
What do we do if there are failed repair attempts already in the tank?
We empty fully and remove old repairs back to sound substrate. Then we apply proper lining from scratch.
Do Al Muntazah tanks need different sealing standards than villas?
Yes. Small rooftop tanks need lightweight lining resistant to thermal movement. Built-in tanks need lining that bonds to very old stone and concrete.
How do we handle many cracks and widespread corrosion in a very old tank?
If corrosion is extensive, partial or full rebuild may be needed. If cracks only, lining is sufficient.
Is sterilization necessary for Al Muntazah tanks like other areas?
Yes absolutely, because past maintenance was poor and bacteria and algae likely grow in the tank. Sterilization is mandatory before return to service.
How much does water tank sealing in Al Muntazah 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 Muntazah.
