Water tank sealing in Madain Al Fahd Jeddah
Madain Al Fahd is a mixed residential district in south Jeddah with villas and apartment buildings near Prince Abdullah Al Faisal Stadium and shopping centres. Tanks here vary in size and age, from relatively new villa tanks to older apartment building tanks. Treatment requires knowledge of different tank types and installation methods.
-
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 Madain Al Fahd
Modern villas have protected ground tanks, while mid-age apartments have roof-mounted tanks without adequate structural support. The method is set out in full on what Water tank sealing involves.
Modern villas and their ground tanks
New villas have ground-level tanks in gardens or under stairs, shaded from direct sun. The main problem here is water seepage into soil and poor insulation against ground moisture.
Mid-age apartment buildings and roof tanks
Apartment buildings aged 15 to 25 years have roof tanks with some thermal protection. Cracks start at joints and corners and expand with temperature swings.
Mixed commercial and residential usage
The area has shops and restaurants alongside homes. Daily usage is mixed and some tanks suffer high pressure from commercial usage density.
The character of Madain Al Fahd
Mixed district: shops at street level with homes above them
The mixed villa and apartment character means tank types and problems vary. Treatment requires knowledge of both ground and roof tank sealing, each with different insulation methods.
What we read before any material is opened
A mixed residential district in south Jeddah, Old Makkah Road on the north, Stadium Road on the east, Madain Al Fahd Road on the west and Al Falah Road on the south. Villas and apartments sit near the stadium, shopping centres, restaurants and neighbourhood mosques.
Cracking in the wall
Lining inspection of ground tanks reveals cracking from external moisture pressure and groundwater stress.
The floor to wall joint
Lining inspection of roof tanks shows cracking from temperature cycling and thermal expansion cycles.
The condition of the old lining
Joint and inlet inspection finds seepage from daily pressure and repeated thermal fluctuations.
Sediment and scale
Ground moisture pressure affects ground tanks strongly, while roof tanks are affected more by heat.
The pipe entries
Ground tanks may show severe internal moisture from continuous external seepage.
The hatch and the vent
Leaks appear differently: slow seepage in ground tanks and sharp leaks at roof tank joints.
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 Al Jamiah Sub-Municipality
Al Jamiah sub municipality spans the older south of Jeddah. Planned districts such as Al Fayha, Al Thaghr and Madain Al Fahd sit beside crowded popular quarters like the Nazlahs and Al Quraiyat, and beside cleared or clearing land in Ghulail, Petromin and Al Thaalibah awaiting redevelopment. Apartment buildings stand close together above dense runs of shops and restaurants along Old Makkah Road and Prince Majid Road. Drainage in the popular quarters is ageing, humid air drifts in from the port and refinery side to the west, and the flat low lying ground holds rainwater in narrow streets.
Questions about this district
Why do ground tanks in villas leak more than roof tanks?
Ground tanks face constant ground moisture pressure. Groundwater and soil humidity weaken the lining from outside.
Do shops and restaurants near villas put higher pressure on shared tanks?
They may. Restaurants and shops use more water and shared tanks may need more frequent inspection and maintenance.
What is the difference between treating a villa tank and an apartment tank?
A villa ground tank needs strong external moisture insulation. An apartment roof tank needs protection from heat and intense daily pressure cycles.
Does temperature cycling cause more damage than steady heat?
Yes. Cycles cause repeated expansion and contraction which compounds existing cracks and creates new ones.
How often should tank lining be replaced in mixed districts like this?
Usually every 10 to 15 years depending on usage and climate. High commercial use may require replacement sooner.
Can different insulation materials be used for ground and roof tanks?
Yes. Ground tanks need stronger defence against soil moisture. Roof tanks need protection from heat and UV radiation.
How much does water tank sealing in Madain Al Fahd 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 Madain Al Fahd.
