Water tank sealing in Al Misyal Al Jadid Makkah
Al Misyal Al Jadid is a new quarter built under the Crown Prince scheme in the south of the city, with modern apartment blocks and newly built villas separated by wide empty plots. Tanks here are newly constructed and need early protection because high salinity in groundwater begins attacking internal surfaces immediately. Treatment focuses on preventing fine cracks before they form and protecting joints and pipe entries from early leaks.
-
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 Misyal Al Jadid
Buildings and villas here are recently constructed and have not yet weathered many seasonal cycles. New tanks need preventive protection against early rust and cracking. The method is set out in full on Water tank sealing in detail.
Villas and apartment blocks newly built
Villas and residential buildings in Al Misyal Al Jadid were constructed in recent years and have not yet faced extended seasonal testing. New tanks may benefit from preventive sealing before fine cracks appear from soil expansion or summer heat.
Groundwater is high in salinity
Groundwater in south Jeddah carries high salt concentration. Salt reacts with tank surface and causes corrosion and early cracking at joints and floor.
Fine cracks in joints and floor
New tanks experience natural expansion and contraction from extreme summer temperatures. Joints between floor and walls and pipe entries are the weakest points and where leaks first appear.
The character of Al Misyal Al Jadid
New development: ongoing construction and vacant plots between the homes
Al Misyal Al Jadid is a newly built quarter with villas and modern apartments, and tanks here are young. Treatment focuses on preventive protection from the start, recognising that saline groundwater is the primary threat to new tanks.
What we read before any material is opened
A newly built residential quarter in the south along the southern extension of Ibrahim Al Khalil Road, between Al Hajlah Al Jadid and the Saudi German Hospital, with modern buildings and new villas. Qutbah bin Amer Street is the main thoroughfare.
Cracking in the wall
The first inspection focuses on fine cracks in the tank floor and walls, which may not be obvious but leak water slowly over time.
The floor to wall joint
Joints between floor and walls and pipe entries need close inspection as they are the tank's weakest points and where leakage often begins.
The condition of the old lining
Dissolved salts in groundwater leave deposits on the tank's internal surface and must be removed before new sealing is applied.
Sediment and scale
High moisture from nearby groundwater enters through fine cracks and causes existing sealing to degrade.
The pipe entries
Small cavities and hairline cracks beneath the tank surface create ideal conditions for slow leaking and continuous corrosion.
The hatch and the vent
Salt residue and deposits on the internal surface reduce the effectiveness of new sealing, so cleaning and sterilisation are essential before applying protective coating.
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 South Makkah Sub-Municipality
South Makkah sub municipality is the belt of Crown Prince schemes south of Al Ukayshiyah, along the Al Laith road and the extension of Ibrahim Al Khalil Road to the Fifth Ring Road and the Non Muslims bypass. Most of it is still bare: granted plots awaiting houses, new villas standing alone, open building sites and unfinished paving and drainage. Wadi Uranah and its tributaries cross the low ground and hold water after rain, hills close it in, and rodents, reptiles and scorpions shelter in stacked materials and foundation pits before the neighbourhoods fill up.
Questions about this district
Do new tanks need sealing straight after construction?
Yes. New tanks benefit from preventive sealing at once. Salt and groundwater begin reacting with the surface from day one.
What causes fine cracks in newly built tanks?
Soil expansion and concrete expansion from extreme heat and saline groundwater cause small cracks in the floor and joints.
Do villas have different tank types from apartment buildings?
Yes. Villas typically have smaller tanks, often placed directly on the roof, exposing them to intense summer heat.
Does preventive sealing prevent leaks completely?
Good sealing greatly reduces leakage and shields the surface from salt attack. Regular maintenance helps catch early problems.
How often do new tank joints need treatment?
Joints need thorough treatment when new. After that periodic maintenance tips preserve the seal quality.
Does saline water affect how long the sealing lasts?
Yes. Salt causes gradual sealing degradation. High-quality sealing lasts longer and refreshing it every few years preserves protection.
How much does water tank sealing in Al Misyal Al Jadid 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 Misyal Al Jadid.
