Water tank sealing in Al Umrah Al Jadidah Makkah
Al Umrah Al Jadidah is a new planned residential district on Madinah Road near the Fourth Ring Road, with villas and apartment buildings spread across wide plots. Tanks here are newer than in older quarters but face pressure from heavy chalk soil and slow ground movement. Sealing focuses on preserving modern tanks from early deterioration.

Why the job is different in Al Umrah Al Jadidah
Most tanks in Al Umrah Al Jadidah were built in the last 10 to 15 years and remain in relatively good condition, though fine cracks are starting to appear from chalk soil movement. The method is set out in full on Water tank sealing in detail.
Tanks buried beneath wide courtyards
Villas here have spacious courtyards and tanks are buried at relatively uniform depths. But the chalk soil moves slowly with seasonal moisture changes and tanks settle gradually over time.
Flexible pipes and modern fittings offer some protection
Modern installations use flexible rather than rigid piping, reducing crack formation. However tank connections to the foundation may still separate during ground movement.
Groundwater is low but chalk soil retains internal moisture
The water table is not high here, but chalk soil holds internal moisture. This moisture interacts with modern building materials and may accelerate slow corrosion.

Open in Google MapsWhat we read before any material is opened
A planned residential district on Madinah Road near the Fourth Ring Road, east of An Nawwariyah. Villas and apartment buildings are distributed across wide plots with the Moonlight family park, small supermarkets, mosques including Ibn Al Qayyim, schools and health centres.
Cracking in the wall
Fine cracks appear in new tanks from slow chalk soil movement and incomplete settling.
The floor to wall joint
The floor-to-wall joint may separate slightly from uneven subsidence despite modern construction.
The condition of the old lining
Flexible piping offers better protection but connection points to the tank body may remain weak.
Sediment and scale
Chalk soil retains internal moisture year-round despite relatively low surface groundwater.
The pipe entries
The tank lies buried at roughly 1 to 2 metres depth, usually surrounded by gravel and sand layers.
The hatch and the vent
Early warning signs include damp paint or hairline cracks in the floor near the tank.
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.
The character of Al Umrah Al Jadidah
New development: ongoing construction and vacant plots between the homes
The new planned residential character means most tanks were built to modern standards with uniform design. But new construction does not mean freedom from problems-slow ground movement and internal soil moisture affect even new tanks. Sealing here emphasizes preserving original quality and early preventive action.
Questions about this district
Do new tanks in Al Umrah Al Jadidah not need sealing?
New tanks meet better standards but still need maintenance and sealing. Ground movement and internal soil moisture can create cracks after several years.
When should we begin sealing a new tank?
As soon as external dampness or fine cracks appear. Delay allows deeper penetration.
Does the chalk soil here require a different sealing approach?
Yes. We use materials that withstand ground movement and internal soil moisture, not just external pressure.
Do tanks on apartment rooftops need different sealing?
Rooftop tanks here face sun heat and cold exposure. Sealing must protect against temperature cycling as well as moisture.
Are fine cracks in a new tank dangerous?
They appear small but widen over time from soil movement. Early repair costs less than waiting until cracks become large.
Should we assess the soil before sealing begins?
Yes. We inspect the foundation and surrounding soil condition. If soil is settling or moving, additional foundation treatment may be needed.
How much does water tank sealing in Al Umrah Al Jadidah 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 Umrah Al Jadidah.
