Water tank sealing in Al Taysir Makkah
Al Taysir is a densely built residential district west of the Grand Mosque, filled with high-rise hotel towers and apartment blocks housing Umrah pilgrims. The large tanks perched on the roofs of these towers face direct sun exposure, extreme heat and constant expansion-contraction cycles. Worn or defective lining allows water to seep into walls and ceilings below.
-
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 Al Taysir
Most buildings are tall apartment blocks and hotel towers constructed in recent decades, with large rooftop tanks directly exposed to the sun and intense heat. The method is set out in full on Water tank sealing in detail.
Large tanks mounted on high-rise rooftops
Hotels and tall apartment blocks in Al Taysir contain large water tanks on roofs to supply dozens of units. The tanks face direct sunlight all day and temperatures reach 50°C.
Cracks in joints from constant thermal cycling
Intense heat causes daily expansion and contraction of tank and lining. The joint between tank floor and wall and around pipe entries cracks first, and water seeps into walls and ceilings below.
Seepage moisture damages internal walls
Continuous leaking from worn tanks allows water to percolate into apartment walls and interior passages. Moisture causes dampness, mould growth and structural cracking.
The character of Al Taysir
Apartment district: residential blocks, repeated floors and shared entrances
High-rise apartment and hotel towers mean tanks are large and elevated, exposed directly to sun. Lining must be thicker and stronger to resist pressure, intense heat and the constant expansion-contraction cycle.
What we read before any material is opened
A densely built residential quarter west of the Grand Mosque, bounded on the south by Umm Al Qura Road and on the north by Al Taysir Street, bordered by Jarwal, Al Zahir and Al Mansour.
Cracking in the wall
Cracks start around entry and exit pipe joints where water flows under pressure and heat affects the joint.
The floor to wall joint
Floor-to-wall joints in the tank crack first from heat, water pressure and slow structural movement.
The condition of the old lining
The tank's inner surface erodes from water, minerals and salt deposits, and old lining gradually peels away.
Sediment and scale
Moisture, heat and salt are all present together, so lining degrades faster than in other areas.
The pipe entries
The main leak source lies in fine cracks and joints around inlet and outlet pipes and tank corners.
The hatch and the vent
Water seeps from the tank and dampness appears on ceilings and walls of lower-floor apartments within days.
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 Ghazza Sub-Municipality
Al Ghazza sub municipality wraps around the north and west of the Grand Mosque, from Al Shamiyah, Al Qararah and Shaib Amir round to Jarwal and Al Taysir. Large tracts were cleared for the northern expansion and the Rua Al Haram scheme, leaving excavated ground and open construction sites beside ageing blocks that now serve as dense seasonal lodgings in Jarwal and Al Taysir. Old flood paths still fall from Jabal Qaiqaan and Jabal Khandamah towards the mosque, and markets and eateries crowd Al Masjid Al Haram Road and Umm Al Qura Road.
Questions about this district
Does failing tank lining cause water to leak directly into apartments below?
Yes. Water seeps from joints and cracks and runs down interior walls and ceilings to units beneath.
Why do tanks in Al Taysir crack more than other areas?
Intense heat and direct sun exposure on rooftops cause rapid daily expansion and contraction cycles.
Does an old tank need complete replacement or just resealing?
If structurally sound, new lining is sufficient. If cracks are deep or the shell is fractured, replacement may be necessary.
Does leaking tank water threaten the building's structural integrity?
Yes. Continuous seepage weakens walls and columns, causes permanent dampness, mould and structural cracking.
How many reseals can a tank have before replacement becomes the better choice?
If resealing is needed every year or two, the tank may be better replaced than repeatedly patched.
Do high-rise apartments need stronger tanks than low buildings?
Yes. Pressure is higher and roof heat is more intense on tall towers, so lining needs greater thickness and higher quality.
How much does water tank sealing in Al Taysir 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 Taysir.
