Tank leak repair in Mughammas Makkah
Mughammas is an industrial storage zone on the eastern fringe beyond Al Sharai on the main road. Tanks here are large and heavy, serving warehouses and facilities. Seasonal flooding from Wadi Mughammas and wet soil exert outward pressure on buried tanks, and leaks appear from the sides and floor, not the top.

Why the job is different in Mughammas
Warehouses and facilities here hold large volumes of water for operations and cooling. Underground tanks face seasonal groundwater pressure and periodic inundation. The method is set out in full on Tank leak repair in detail.
Large buried tanks under heavy water load and seasonal floods
Warehouses contain large deep tanks below ground. Seasonal wadi floods raise the water table, and outward pressure on the tank walls causes leaks through the sides and floor.
Wet soil and salt accelerate concrete deterioration
Soil here is always damp because the wadi is near and the water table is high. Salt and moisture erode concrete inside and out, and small cracks widen quickly.
Heavy use and continuous pressure stress the tanks
Facilities fill and draw from tanks constantly. Sustained pressure, pump pulses and vibration from machinery fatigue the concrete and seams.
The character of Mughammas
Industrial area: workshops, warehouses and loading yards
An industrial storage zone means large heavy tanks buried underground. Outward pressure from floods and groundwater is entirely different from inward water pressure, so repair must account for structural pressures, not just cracks.
Where the water leaves decides how it is repaired
An industrial and storage zone on the far eastern fringe, open land and warehouses named after Wadi Al Mughammas, now called Wadi Al Akhdar. The district is bounded by Al Tariqi and Al Khatm hills and adjoins Al Rashidiyah and Al Kawthar; the wadi can flood in heavy rain.
Damp and salt on the outside wall
Horizontal and mesh cracks appear on tank floors due to outward pressure from groundwater and seasonal floods.
The kind of crack
Large inlet and outlet pipes leak at wall connection points under external pressure.
The wall to floor junction
Rapid loss occurs during floods when groundwater rises above the base level.
Pipe entries
Persistent dampness and soil salt erode concrete from outside and inside simultaneously.
The condition of the old lining
Failure points lie in deep cracks and seams under external pressure; leaks develop from structural weak points.
What the tank is made of
Seasonal loss increases during heavy rains and floods, and may persist after floodwaters recede if cracks are not repaired.
How we work
-
1
Inspect and locate the leak
We close the float valve and the outlet, mark the water level and watch it fall, then check the fittings and the wall beside it. That separates a tank leak from a pipe leak or a float valve that never shuts.
-
2
Drain, clean and dry
We empty the tank, lift the sediment off the base, wash back to sound concrete and let the surface dry. No repair holds on a damp or dusty face.
-
3
Repair the cracks and the entries
We cut the crack open, fill it with a non-shrink mortar, inject anything still weeping and rebuild around the pipe sleeve. A joint that moves takes a flexible detail, not a rigid one.
-
4
Refill, test, then sterilise
We refill, read the level again to confirm the drop has stopped, then sterilise before the water is used, because the tank has been open with tools and hands inside it.
What tank leak repair includes
-
A marked level test
A reading before and after with everything shut, which establishes that the loss is the tank and not the plumbing.
-
Draining and sediment removal
Water and silt out of the base, so the floor and the walls can be seen as they really are.
-
Pressure wash and dry back
The weak layer and the dust come off, because a repair only holds on sound concrete.
-
Cracks opened and filled
The crack is cut open and filled with a non-shrink mortar, and anything still weeping under water pressure is injected.
-
Refill and a recorded test
We refill, read the level again and write the reading down, so the result is not a matter of opinion.
-
Sterilised and back in service
A wash and a sterilisation once the material has cured, and guidance on running the first fill off before the water is used.
What is different about Al Sharai Sub-Municipality
Al Sharai is the eastern growth front of Makkah along King Faisal Road and the Taif road. Settled quarters sit beside recently renamed schemes where plots are still vacant and buildings are going up, so construction sites, fill and open excavations lie next to occupied homes. Wadi channels such as Wadi Mudarraja, Wadi Al Sharai and Wadi Al Mughammas carry flash floods after rain and dry out to damp silt, while dust blows off the open hills. Roadside shops, restaurants and warehouses line the Taif road, and to the east the area shades into villages, palm farms and springs.
Questions about this district
Why are leaks in Mughammas more common from the bottom than the top?
Outward pressure from floods and groundwater presses on tank walls and floor. Bottom leaks are most common because pressure concentrates there.
Do seasonal floods cause new leaks each time?
Yes. Floods raise the water table and increase outward pressure. Any existing cracks widen further under added pressure.
Are large tanks harder to repair than small ones?
Yes. Large tanks need complete drainage and often lie deep below ground. Repair needs heavy equipment and longer timelines.
Does external pressure harm new tank lining?
Yes. Lining is applied inside and outward pressure pulls it from the walls. Structural repair must come first.
How do we protect tanks from future floods?
Sealing and regular maintenance help. But if external pressure is very high, we may need to raise the tank or build a protective wall.
Does slow leakage from a buried tank harm building stability?
Yes. Water weakens soil beneath the base and the tank may settle. This causes uneven subsidence of the warehouse.
How much does tank leak repair in Mughammas 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 Mughammas.
