Water tank sealing in Al Manar Jeddah
Al Manar is a mixed-use district stretching from Hada Al Sham Road in the north down to Al Samir in the south, containing villas, modest-priced apartment buildings and shopping centres. Tanks here serve different income levels and usage patterns. Pressure on tanks varies between family villas and tall apartment blocks.
-
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 Manar
Tanks range from older models to relatively recent ones. Some villas date back 15 years and apartment buildings vary from 5 to 20 years old, meaning varied levels of wear. The method is set out in full on how we approach Water tank sealing.
Older villas have corroded tanks
Some villas in Al Manar were built 15-20 years ago and their tanks now show real wear. Deep cracks and floor leaks are very common in these properties.
Tall apartment blocks need sustained water pressure
Residential apartments in Al Manar typically stand 5-8 storeys. Water must climb at high pressure. Overhead tanks in these blocks suffer cracks from sustained pressure.
Commercial shops and high water demand
Shops, restaurants and cafes in Al Manar Plaza and Al Yasmin Mall use water at high intensity for cleaning and service. Shared tanks here face heavy use.
Landmarks of Al Manar
Access to Al Manar runs via Hada Al Sham Road north and Al Samir Road south, with the expressway as a clear eastern boundary. The district is surrounded by Al Samir sands and other residential quarters.

What we read before any material is opened
A mixed district stretching from Hada Al Sham Road north to Al Samir south, east of the expressway. Villas and modestly priced apartment buildings share blocks with shopping centres such as Al Manar Plaza and Al Yasmin Mall on its fringe.
Cracking in the wall
Initial inspection reveals old sediment and oily buildup from shops and restaurants tied into the shared water system.
The floor to wall joint
Deep narrow cracks appear on old tank floors and high-rise blocks at points of peak pressure.
The condition of the old lining
Floor-to-wall joints expand and corrode fast in tanks serving tall buildings.
Sediment and scale
Main pipe entry in shared tanks suffers irregular pressure from interrupted use by different tenants.
The pipe entries
Internal walls need strong sealing especially in tanks serving commercial shops because water may carry contaminants from use.
The hatch and the vent
Sterilisation must be periodic especially in shared tanks because heavy interrupted use encourages bacterial growth.
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 old tanks in Al Manar need sealing now?
Tanks at 15-20 years old now show real wear. Small cracks today become full leaks tomorrow.
Do apartments and villas need different sealing?
Yes. Villas are stable with even pressure. Tall apartments need stronger pressure-resistant sealing.
Are shared tanks in commercial centres more prone to leakage?
Yes. Heavy continuous use accelerates wear. Leaks happen faster than in normal residential tanks.
Can we seal a tank partly while it is still in use?
Very difficult in apartments because residents need constant water. We may work in night stages or move usage to a reserve tank.
How old is the sealing in these old tanks?
If old sealing exists it may already be damaged. We remove the old layer and apply new sealing.
Do modest building prices mean cheap-quality tanks?
Possibly, but the tank itself is ordinary concrete. The issue is age and heavy continuous use, not quality.
How much does water tank sealing in Al Manar 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 Manar.
