Water tank sealing in Al Lulu Jeddah
Al Lulu is a narrow coastal strip facing the Red Sea, with beach resorts, luxury villas and modern apartment buildings along Obhur Road. Salt water and coastal humidity directly attack water tanks. Tanks here suffer rapid corrosion from salt, wind and harsh weather cycles.
-
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.

Why the job is different in Al Lulu
Buildings here are relatively new but their tanks face salt corrosion and very high humidity. Leaks are common at joints and floor seams. The method is set out in full on Water tank sealing in detail.
Salt and sea spray damage to the inner surface
Tanks sit close to the sea and salt penetrates walls and floors through hairline cracks. Salty vapour causes rapid lining corrosion and repeated leaks.
Luxury villas and resorts have large tanks at difficult depths
Resorts and seaside villas have elevated and very deep ground tanks. Reaching the tank floor is difficult and cracks at floor and wall corners run deep and collect moisture fast.
Very high humidity accelerates corrosion and biological growth
Relative humidity on the coast exceeds 90%. Standing water in tanks promotes algae and bacterial growth. Leaks begin at hairline cracks then enlarge quickly.
The character of Al Lulu
Coastal area: high humidity and salt air through the year
A luxury coastal area means large tanks serving resorts and high-end villas. Salt water and coastal humidity cause corrosion at an unusual rate, so lining here requires materials with high resistance to salt and salt-spray.
What we read before any material is opened
A narrow coastal district on the Red Sea between Al Zumurrud to the north and Al Amwaj and Al Shira to the south, with resorts, villas and modern buildings along Obhur Road.
Cracking in the wall
Salt corrosion shows on the floor and corners and floor-to-wall joints from continuous salty spray exposure.
The floor to wall joint
Hairline cracks start at corners and joints and widen gradually from concrete expansion caused by moisture.
The condition of the old lining
Pipe entry points and fixtures corrode faster than flat surfaces and salt enters around pipes.
Sediment and scale
High humidity and standing water promote biological growth and green algae on tank walls.
The pipe entries
Floor and corners are first corrosion zones because water pools there and salt deposits fast.
The hatch and the vent
Biological growth and moisture cause water discolouration and odour even without visible leaks.
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 Dhahban Sub-Municipality
Dhahban sub municipality is the northern coastal strip of Jeddah, running from the north bank of Sharm Obhur up to the old village of Dhahban and Salman Bay. Its districts are recently built, with owner occupied villas and apartments, beach resorts and chalets on the shore, and land subdivisions still being developed. Nearness to the sea keeps humidity high all year, irrigated lawns in villas, resorts and district parks hold water, Wadi Obhur and the vacant plots between buildings give rodents and reptiles shelter, and the old fishing village of Dhahban gives the far north a rural edge.
Questions about this district
Why do our tanks leak faster than in other areas?
Sea salt and high coastal moisture attack concrete and protective layers more quickly. Hairline cracks widen faster in a coastal environment.
Is sealing one leak enough or do we need full tank lining?
Sealing one leak is only temporary. In a coastal setting, complete lining of the inner surface is necessary to prevent new leaks.
Does salt water damage the tank body itself?
Yes, salt weakens concrete from inside and outside. A new lining protects the tank from further deterioration spreading.
Does the lining protect against salt corrosion or does it need regular checks?
Lining offers strong protection but high humidity requires periodic inspection to ensure the lining stays sound.
How many times do we empty the tank for sealing?
Once. We empty it fully, repair cracks and joints, line it and sterilise before refilling.
Do resorts and villas need different treatment from standard villas?
Yes. Large deep tanks need deeper inspection and floor access requires special planning.
How much does water tank sealing in Al Lulu 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 Lulu.
