Water tank sealing in Al Rahmaniyah Jeddah
Al Rahmaniyah is a newly built mixed residential district in north Jeddah, with villas, apartments and commercial plots on the main Al Furusiyah Street. Tanks here suffer multiple problems because the district straddles clean residential zones and busy commercial areas. The main issues are leaks from upper joints due to pipe seepage and poor installation, and base leaks from moisture in shared passages and foundations.
-
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 Rahmaniyah
The district is new but contains a mix of residential villas, apartment buildings and shops, and tanks show multiple problems from poor installation, pipe seepage and moisture from adjacent commercial areas. The method is set out in full on how we approach Water tank sealing.
Commercial zones and high humidity
The main Al Furusiyah axis has shops, restaurants and services, and humidity from daily washing and cleaning is high. Tanks in neighbouring buildings are exposed to high moisture from shared foundations and passages.
New pipes and poor installation
The district is new and pipes and tanks are newly fitted, but installation is sometimes rushed and poor. Upper joints leak because pipes were not fitted tightly, and internal pressure makes leaks worse.
Mix of villas, apartments and shops
The district contains different building types and tank sizes; some deep and some shallow, some villas and some commercial apartment buildings. Treatment needs a different approach for each type.
The character of Al Rahmaniyah
Mixed district: shops at street level with homes above them
A mixed district means villas, apartments and commerce together, so tanks are diverse and need different approaches. Humidity from commercial zones and shared passages compounds the sealing and lining challenges.
What we read before any material is opened
A mixed and recently developed residential district in north Jeddah stretched along Al Furusiyah Street between Al Furusiyah and Al Salihiyah, beside Al Falah and Al Hamdaniyah, with new villas and apartments and commercial plots on the main axes.
Cracking in the wall
Pipes in residential villas need careful inspection to confirm no leaks at upper joints before sealing begins.
The floor to wall joint
Commercial zones and shared passages supply continuous moisture sources affecting neighbouring tanks.
The condition of the old lining
Lower joints and shared foundations between villas and buildings may be the cause of recurring leaks.
Sediment and scale
Standing water and dampness under foundations cause tank base leaks over time.
The pipe entries
Differences in tank depth and size across the district need different lining and sealing approaches.
The hatch and the vent
Clean water needs protection from seasonal and sustained humidity coming from commercial areas and shared passages.
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 Taybah Sub-Municipality
Taybah sub municipality covers the newly built districts of north east Jeddah along Al Haramain Road and Asfan Road. New villas and apartment buildings stand among vacant plots, building sites and half finished subdivisions. Al Hamdaniyah is the oldest and densest part with its markets and shops, while Al Furusiyah, Al Bashair, Al Rahmaniyah, Al Falah and Al Salihiyah are mostly recent. The ground is inland and away from the sea, dry and dusty, rest houses, camps and stables on the fringes draw flies and crawling insects, and constant digging and construction stirs rodents out of the empty plots.
Questions about this district
Does poor initial installation cause ongoing leaks in Al Rahmaniyah?
Yes. Many tanks here were not properly installed from the start. Refitting and resealing the pipes is essential before beginning sealing.
Does humidity from commercial zones affect residential tanks next door?
Yes. Moisture penetrates shared foundations and passages and causes leaks from tank bases.
What is the difference between sealing a villa tank and a commercial building tank?
A villa tank is usually smaller and lower pressure, while a commercial building tank is deeper and heavier and needs stronger lining.
Do new tanks in Al Rahmaniyah need immediate repair or can they wait?
If leaks are minor they may wait. But if from pipes or joints, repair must be immediate because leaks will worsen with pressure.
Does sealing alone solve moisture problems from foundations and passages?
No. External sealing protects from direct water but moisture from foundations needs drainage and additional sealing beneath the tank.
Should we inspect foundations and passages before sealing the tank?
Yes. If leaks are from below, foundations and passages must be inspected and structural problems ruled out before treatment.
How much does water tank sealing in Al Rahmaniyah 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 Rahmaniyah.
