Water tank sealing in Al Wurud Jeddah
Al Wurud is a relatively modern residential district built on the site of the old airport, with villas, apartment blocks and mixed-use commercial buildings. Tanks here vary in size but are newer than those in Bani Malik, making maintenance simpler. The district is expanding rapidly and ongoing construction puts stress on tank structures.
-
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 Wurud
Buildings here are newer than neighbouring quarters, but ongoing development and construction excavation can cause foundation settlement and tank cracking. The method is set out in full on what Water tank sealing involves.
New villas have modern tanks but risk settlement damage
Villas in Al Wurud were built on the old airport site where the sub-layer may be unstable. New construction work and excavation cause vibrations that stress buried tanks.
Apartment blocks need regular maintenance on rooftop tanks
Residential buildings carry large rooftop tanks. Seasonal moisture and temperature swings cause thermal expansion and lining stress.
Rapid development creates new tank pressures
Ongoing construction and excavation throughout the district cause ground vibrations. Tanks near active build sites face additional structural strain.
Landmarks of Al Wurud

What we read before any material is opened
A mixed residential district between King Fahd Road and Prince Majid Road, developed on the site of the old airport. It contains villas, apartment blocks and small commercial buildings, neighbours Al Naseem to the east and Bani Malik to the north, and houses Al Habbash Mosque, Al Wurud Mosque, sports pitches and neighbourhood parks.
Cracking in the wall
Mineral deposits from hard water accumulate slowly in newer tanks, but routine cleaning prevents rapid build-up.
The floor to wall joint
Cracks from uneven settlement start at the tank floor and run up the walls.
The condition of the old lining
Pipe inlets and outlets on modern tanks seal better, but may fail under settlement stress.
Sediment and scale
Seasonal rainfall seepage can occur around buried tanks if the surrounding fill was not properly compacted.
The pipe entries
Tank floors may experience uneven settlement, causing water pooling and accelerated corrosion.
The hatch and the vent
Post-treatment sterilisation is vital especially after construction vibrations, as small cracks may allow contaminants to enter.
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 Sharafiyah Sub-Municipality
The Al Sharafiyah sub municipality runs across central Jeddah from Al Ruwais near the Corniche eastwards through Al Sharafiyah, Al Wurud and Bani Malik to Al Naseem at the Haramain Road. It was among the first areas to grow beyond the old wall, and it is dominated by dense apartment blocks over shops along King Fahd Road and Palestine Street, with old popular quarters, the Bani Malik market, car workshops and storerooms. Ageing buildings, worn drainage and the refuse of restaurants and markets make cockroaches and rodents the most persistent pests, and humidity rises towards the sea.
Questions about this district
Does foundation settlement from new building work affect buried tanks?
Yes. Settlement and vibrations from excavation and construction add stress to tanks and accelerate cracking.
Do villa and apartment block tanks need different sealing methods?
Yes. Buried villa tanks need deep sub-layer inspection, while apartment block tanks need rooftop and high-level seal checks.
Does tank sealing increase resistance to construction vibrations?
Not directly, but new lining offers better protection against new cracks that vibrations may trigger.
How often should a tank be inspected if near an active construction site?
Monthly or bi-monthly inspections are best while building work continues, to catch new cracks early.
Can a tank be sealed before neighbouring construction finishes or should we wait?
Sealing is possible but new cracks are more likely to appear due to ongoing vibrations.
Does the old airport site soil affect tank stability?
Yes. The old site soil may not be fully compacted, causing uneven settlement of tanks.
How much does water tank sealing in Al Wurud 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 Wurud.
