Water tank sealing in Al Khalidiyah Jeddah
Al Khalidiyah is a northern coastal district with large villas and gated compounds, each holding one or more tanks on roofs or buried beneath. Salt spray from the nearby sea and high humidity accelerate lining failure, and cracks form rapidly in coastal zones exposed to constant moisture and salt air.
-
Potable-rated materials
Linings and disinfectants cleared for drinking water tanks, not general-purpose products.

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 Khalidiyah
Most villas in Al Khalidiyah were built in recent decades, and their rooftop and underground tanks deteriorate rapidly due to salt air and high humidity from the nearby sea. The method is set out in full on our Water tank sealing service.
Exposed rooftop tanks on open surfaces
Large villas keep rooftop tanks open to direct salt spray and humidity. Constant salt exposure and moisture cause rapid rust and cracking at corners and floor seams.
Deep tanks beneath villas and compounds
Gated compounds and luxury villas contain deep underground tanks. These face soil moisture and seepage from surrounding excavation walls.
Pipe entries and complex networks in large properties
Large villas and compounds have complex piping networks from tank to each floor and bathroom. Entry points and joints are prone to stress cracks under high pressure and salt intrusion.
The character of Al Khalidiyah
Villa district: private plots, gardens and a boundary wall to every house
Large villas and gated compounds in Al Khalidiyah hold multiple tanks, some rooftop and some deep. The coastal location and salt air mean linings must use salt-resistant materials, and deep tanks often need external waterproofing as well.
What we read before any material is opened
A northern residential district on the corniche between King Abdulaziz Road and Saud Al Faisal Road, bordered by Al Andalus, Al Rawdah, Al Salamah and Al Zahra. The main housing consists of large villas and closed compounds with some apartment buildings on the fringes.
Cracking in the wall
Pipe entry points in rooftop tanks corrode quickly from salt and humidity, forming the largest leak sources in coastal villas.
The floor to wall joint
Floor-to-wall joints in salt-exposed tanks crack and fail, especially where old cement meets the concrete base.
The condition of the old lining
Vertical and horizontal cracks appear in linings from daily heat expansion and contraction plus salt deposition.
Sediment and scale
Soil moisture around deep tanks is very high due to sea proximity and groundwater, accelerating external lining failure.
The pipe entries
Previous lining in older villas was often applied with weak materials or poor technique, requiring full removal and fresh application.
The hatch and the vent
Salt and sediment accumulate quickly on tank floors in coastal areas, requiring thorough cleaning before new lining is applied.
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 New Jeddah Sub-Municipality
New Jeddah sub-municipality lies at the heart of the northern city near the corniche and takes in Al Rawdah, Al Salamah, Al Zahra and Al Khalidiyah. These are established upmarket districts of villas, compounds and modern apartment blocks, crossed by Prince Sultan Road and Tahlia Street with their restaurants and hotels. The nearby sea keeps humidity high for most of the year and irrigated gardens hold moisture in the soil. Food waste and damp planted areas draw cockroaches, ants and mosquitoes, and in packed apartment blocks pests move between units through shared service shafts and refuse rooms.
Questions about this district
Is rapid tank failure in Al Khalidiyah due to salt from the sea?
Yes. Salt air from the corniche accelerates failure. Exposed linings lose effectiveness faster here than in inland areas.
How often should a tank be sealed in Al Khalidiyah?
In coastal areas, every 5 to 7 years. Salt air and humidity shorten lining lifespan.
Does a deep tank beneath a villa need different treatment than a rooftop tank?
Yes. Underground tanks face soil moisture and earth pressure. Treatment begins with external wall sealing first.
Does tank leakage always mean the lining is cracked?
Not necessarily. Leaks may originate from pipe joints or floor-to-wall seams. Inspection identifies the source before repair.
How do you handle tanks in gated compounds and luxury villas?
We fully empty the tank and inspect its internal and external structure. We repair cracks, apply new lining, sterilise and return it to service.
Does tank sealing protect against soil moisture in deep tanks?
The new lining protects against water escaping the tank interior. For external soil moisture, additional exterior sealing around the tank itself may be needed.
How much does water tank sealing in Al Khalidiyah 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 Khalidiyah.
