Water tank sealing in Al Naeem Jeddah
Al Naeem is a commercial and mixed zone north of Jeddah where hotels, restaurants and shops sit alongside apartment blocks and small villas. Tanks here feed multi-use buildings and experience high, continuous water pressure. Heavy usage and harsh hot seasons accelerate wear and leaks.
-
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 Naeem
Tanks here are large and feed hotels, restaurants and residential buildings simultaneously, and the high water pressure and heavy usage cause faster deterioration than in ordinary residential areas. The method is set out in full on our Water tank sealing service.
Large tanks feeding hotels, restaurants and multi-use buildings
Tanks here are massive and feed commercial and residential buildings at the same time. Water pressure is very high and flow is continuous, causing constant stress on walls and joints.
Hot seasons and heavy consumption accelerate wear
Restaurants and hotels consume water heavily throughout day and night and intense heat makes water slightly more acidic. Internal corrosion happens quickly and cracks appear on bases and joints.
Location between two main roads and vibrations from traffic
The zone sits between Madinah Road and Prince Sultan Road and heavy traffic causes periodic vibrations. The tank may shift slightly with each heavy vehicle and this causes cracks in walls and base.
The character of Al Naeem
Commercial area: offices, showrooms and small stores
Al Naeem is a commercial zone mixed with residential, meaning tanks are very large and under high water pressure. Construction is relatively modern and tanks may be good initially, but continuous pressure and heavy usage accelerate wear. Sealing must be robust and inspection frequency must be regular and close.
What we read before any material is opened
A northern district between Madinah Road and Prince Sultan Road where the commercial character dominates. Hira Street and Al Naeem Street, also known as Al Thalatheen, carry restaurants, cafes, hotels and shopping centres including Hira International Market, while the inner blocks hold apartment buildings and small villas.
Cracking in the wall
Cracks appear in walls and joints due to high water pressure and vibrations from traffic on the two main roads.
The floor to wall joint
Leaks occur at inlet and outlet pipes and fasteners that move with vibrations and thermal expansion cycles.
The condition of the old lining
Chemical corrosion from fresh water and dissolved minerals gradually weakens the tank's inner layer silently and progressively.
Sediment and scale
Moisture from leakage through cracks and condensation makes the area around the tank very damp.
The pipe entries
The tank floor and side joints experience very high water pressure from the weight and height of the water column.
The hatch and the vent
Old sealing layers may be cracked or losing adhesion due to vibrations, heat and continuous pressure cycles.
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 Obhur Sub-Municipality
Obhur sub-municipality runs along Jeddah's northern shoreline from Al Shati up to Obhur Creek. It mixes large villas and gated compounds with busy commercial spines of restaurants, cafes, markets and hotels. Sea humidity is high for most of the year and salt laden breezes keep timber and render damp, while irrigated gardens and lawns surround the corniche and the villa plots. Standing irrigation water, dense planting and food waste from the hospitality strip suit cockroaches, mosquitoes and ants, and the chalets and rest houses scattered along the creek stand empty for long spells, which lets insects and rodents settle undisturbed.
Questions about this district
Why do large hotel tanks need stronger sealing?
Water pressure in a large tank is much higher and walls experience greater mechanical stress. Sealing must be stronger and more flexible.
Does heavy water consumption cause faster corrosion?
Yes. Continuous flow and fresh water carry dissolved minerals and slight acids that cause slow chemical wear from inside.
Do vibrations from main roads affect tank integrity?
Yes. Periodic vibrations may cause gradual cracking in walls and joints, especially if the tank is old or weak.
How do we choose sealing type for a hotel tank versus a residential building?
Hotels need stronger sealing with more flexibility to handle high pressure and continuous flow. Residential buildings may need simpler sealing.
Does inspection frequency differ between commercial and residential tanks?
Yes. Commercial tanks should be inspected at least every three months. Residential tanks need only annual inspection.
Does hot water used in restaurants affect the sealing?
Yes. Hot water weakens some sealing materials and causes extra expansion. You may need heat-resistant sealing layers.
How much does water tank sealing in Al Naeem 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 Naeem.
