Water tank sealing in Al Diyafah Makkah

Al Diyafah is a residential district on the old Makkah road north of Al Zahra, containing dense apartment blocks and furnished flats. Tanks here serve hundreds of residents and visitors, and leaks affect water quality and utility bills. With high usage and aging buildings, tanks need regular robust sealing.

  • 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 Diyafah

Buildings were constructed thirty to forty years ago and their residents are transient tourists, temporary residents and workers. Tanks face very high usage pressure. The method is set out in full on Water tank sealing in detail.

The first reason

Tanks on crowded apartment buildings

Al Diyafah apartment blocks contain many units, each serving fifty to a hundred people. Tanks endure very high water pressure and fast, repeated draining. Concrete walls crack under continuous pressure.

The second reason

Small hotels and furnished flats create high moisture and repeated draining

Furnished flats in Al Diyafah demand very high water use and small hotels cause repeated draining and variable pressure. This creates cracks and leaks in tanks.

The third reason

Location between two main streets and pressure from residential density

Al Diyafah lies between Hussain Arab Street and Abdullah Arif Road with very dense buildings. Tanks must store water for large populations and face constant pressure.

The character of Al Diyafah

Apartment district: residential blocks, repeated floors and shared entrances

Al Diyafah is a densely-used residential quarter with transient occupants. Tanks serve hundreds of people and need large capacity and strength. Sealing must withstand continuous high pressure and not degrade rapidly.

Before treatment

What we read before any material is opened

A densely built residential district north of Al Zahra on the old Madinah road, containing apartment buildings and small hotels. It is crossed by Hussain Arab Street and Abdullah Arif Road and bordered by As Salamah, Al Buhayrat, Al Utaybiyah and Al Shuhada.

Cracking in the wall

External surface inspection reveals multiple cracks from high pressure and continuous wall expansion.

The floor to wall joint

Floor-wall joint and seam inspection shows clear and continuous leaking with water dripping easily.

The condition of the old lining

Pipe and pressure entry inspection finds erosion from variable and rapid water pressure.

Sediment and scale

Internal inspection after emptying reveals thick layers of sediment and contaminants from very high usage.

Floor and corner inspection shows rapid erosion and deep cracks from repeated pressure cycles.

How we work

  1. 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. 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. 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. 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

  • A technician inspecting with a flashlight

    Finding where the water leaves

    Carried out drained and dry: cracks, joints, pipe collars and the outer face of the wall.

  • A metal floor drain

    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.

  • A gloved hand applying bait into a joint

    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.

  • A spray nozzle in close detail

    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.

  • A clean kitchen counter after treatment

    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.

  • The visit report being written on a clipboard

    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 Utaybiyah Sub-Municipality

Al Utaybiyah sub municipality covers the old districts north of the Grand Mosque: the hillside quarters of Al Hajun, Al Utaybiyah and Al Bayban, Al Zahir and Al Shuhada at the northern entrance, and the newer Al Zahra, Al Diyafah and An Nuzhah westward. Its building stock is among the oldest in Makkah, stone houses on the hills, packed apartment blocks and sewers decades old, threaded with crowded markets like the Utaybiyah souq and furnished flats that fill in the pilgrim seasons. Wadi Al Zahir and Wadi Al Tanim carry storm water through it, and industrial workshops line Hajj Street.

Questions about this district

Why do Al Diyafah tanks leak more than in other quarters?

Residential density is very high and usage is seasonal. Tanks endure very high water pressure and repeated draining that causes cracks.

Do furnished flats and small hotels worsen leaks?

Yes, very high usage and fast draining create variable pressure on tanks. This causes rapid cracking.

Does one treatment solve the problem forever?

It may not if high pressure continues. Periodic maintenance or tank reinforcement may be needed.

Does leaking affect water quality for residents and visitors?

Yes, leaks may allow contaminants into the tank. Sterilisation and robust sealing are essential.

Does tank size need enlargement or is sealing enough?

If the tank capacity is adequate and leaking is the issue, sealing suffices. If residents complain of water shortage, enlargement may be needed.

How often do Al Diyafah tanks need periodic maintenance a year?

Because of very high usage, we recommend inspection every six months and full sealing every three years.

How much does water tank sealing in Al Diyafah 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 Diyafah.
