Water tank sealing in Al Ammariyah Jeddah
Al Ammariyah is a central residential quarter surrounding Eve Cemetery, Maqbarat Ummina Hawwa, Jeddah's oldest burial ground. The quarter is densely built on a very tight street grid and tanks sit on relatively old apartment rooftops. Ancient soil and naturally high ground humidity in the quarter affect tank foundations, water pressure is stable but irregular from the old network.

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 Ammariyah
The quarter is old and apartment buildings are historically significant, with permanently damp soil below due to the cemetery presence and ancient geological activity. The method is set out in full on Water tank sealing in detail.
Tanks on old apartment buildings with weak foundations
Buildings in Al Ammariyah date from the 1960s to 1980s, and their underground foundations have been weakened by permanent moisture. The tank sits on damp substrate causing seepage from below.
Old network with irregular water pressure
The quarter's water supply is very old with variable pressure. High pressure causes leaks at joints, low pressure causes water stagnation inside the tank.
High ground humidity from the cemetery and soil
The cemetery lies beneath the quarter and soil is permanently damp. Moisture rises from below through basement walls to rooftops and tanks, causing corrosion inside and out.

Open in Google MapsWhat we read before any material is opened
A central residential quarter around Eve Cemetery, the city's oldest burial ground, sitting between Bab Makkah, Al Kandarah and Makkah Road on the landward side of the old town. Older apartment buildings occupy a tight street grid, with Al Matar Street and Khalid ibn Al Walid Street close by.
Cracking in the wall
Cracks in tank walls start from concrete shrinkage caused by permanent moisture and temperature swings.
The floor to wall joint
Pipe connections to the tank leak from irregular pressure in the old unregulated network.
The condition of the old lining
Moisture rises from the damp soil below the quarter and penetrates the tank bottom and lower walls.
Sediment and scale
Weak foundations beneath the tank create ideal conditions for continuous moisture and corrosion.
The pipe entries
Tank bottom accumulates stagnant water and sediment from low pressure and high ground humidity.
The hatch and the vent
Sterilisation and aeration are essential to clear stagnant water and bacteria from permanent humidity and low pressure.
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 Ammariyah
Apartment district: residential blocks, repeated floors and shared entrances
Al Ammariyah is an old central residential quarter surrounding Eve Cemetery with permanently damp soil below. Tanks rest on weak damp foundations, so treatment requires special attention to ground-source moisture and foundation weakness, with regular inspections because humidity is a continuous factor.
Questions about this district
Does the cemetery beneath the quarter affect tank integrity?
Yes. The cemetery lies below and soil is permanently damp. Moisture rises from below and affects the tank bottom and lower walls.
Do weak foundations beneath the tank change the repair method?
Yes. We need full foundation inspection before work starts. If damage is severe, we may need additional reinforcement before lining.
Why does water in Al Ammariyah become stagnant despite tank replacement?
Low pressure from the old network causes water stagnation. Sterilisation and aeration after treatment are essential to clear stagnant water.
Are regular inspections more necessary in Al Ammariyah than other areas?
Yes. Permanent humidity and weak foundations mean the tank needs inspection at least every three months.
How long does treatment take if the foundation is very damp?
We may need extra time to fully dry the outer surface and substrate. Treatment may take two or more days depending on humidity level.
Must we also treat the floor around the tank?
Yes. The floor around the tank collects moisture and seepage from cracks. We treat the floor and surrounding joints to reduce overall humidity.
How much does water tank sealing in Al Ammariyah 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 Ammariyah.
