Water tank waterproofing in Al Thaghr, Jeddah

Al Thaghr sits in south Jeddah near the port and industrial zone, where the dust that settles on rooftops is grey with metal filings and diesel rather than pale sand. Tank water here gathers that dust and holds the sea humidity, so leaks and contamination happen faster than in other districts. The waterproofing job targets both the dust and the damp.

Why tank waterproofing protects your water supply

Al Thaghr is surrounded by heavy transport routes and light industry. Port humidity keeps the older concrete buildings continuously damp, and industrial dust settles on flat rooftops and into tank openings.

Seal before a leak develops

Old Al Thaghr tanks leak water slowly but steadily, and small cracks widen damp into the walls of flats and adjacent surfaces for years.
Repair an existing slow drip

Slow seeping leaves constant moisture on the flat's inside walls, and waterproofing stops this seepage before the building structure weakens.
Keep drinking water free of debris

Summer heat widens cracks and winter damp fills them with water, and the seal protects against this endless cycle of expansion and contraction.
Reduce maintenance over time

The old tank in Al Thaghr can be rescued and used for years more with waterproofing instead of being replaced, extending its lifespan cost effectively.

What changes about water tank waterproofing in Al Thaghr

Al Thaghr tanks require frequent cleaning because the dust load is heavier. Water arrives cloudy after easterly winds that carry fine metal particles. For the whole method, see how we approach water tank waterproofing.

The first reason
Industrial dust coats tank interiors faster

The nearby port and factories release grey dust laden with metal filings, unlike the dry sand at the city edge. It enters through tank openings and settles on the bottom mixed with damp, creating a dark sludge that contaminates the water and damages the concrete below.
The second reason
Sea humidity rusts concrete walls from within

Salt air and constant moisture accelerate concrete corrosion. Tank walls rust and crack, water seeps downward into the flats and adjacent units below. The waterproofing seal stops moisture and halts the rust cycle.
The third reason
Older concrete allows slow leaks to persist

Older concrete in Al Thaghr is porous and small cracks widen with heat and damp cycles. Waterproofing must be robust enough to hold against continuous moisture and prevent seepage through shared building walls below.

What the tank looks like after

A sealed, smooth interior surface

The coating bonds to the concrete or fibreglass and fills any hairline cracks that were present.

No active leaks or seeping

Gaps that were allowing water to seep through the walls or base are filled and covered.

Food-safe lining throughout

Every applied material is rated safe for contact with drinking water.

What is different about South Jeddah

South Jeddah is the working end of the city: the Islamic Port, the industrial city with its warehouses and workshops, and behind them older low rise districts such as Ghulail and Al Khumrah. The roads are built for lorries, and port and factory traffic runs through the night, so the dust that settles here is grey with diesel and metal filings rather than pale sand. Buildings are mostly older concrete with flat roofs and open stairwells that collect it. Sea humidity keeps it damp, and in summer it sets hard on ledges and cladding.

Questions worth asking first

Is cloudy water here caused only by industrial dust?

Industrial dust from port and factories is the main source. But cracks inside the tank also allow dirt and algae in, and waterproofing stops this internal entry point, keeping water clean for longer.

Do shared tanks in apartment blocks need stronger sealing?

Yes, a shared tank serves many flats, so any leak affects all residents. Strong waterproofing prevents moisture entering the walls of lower flats and shared party walls that carry the building weight.

After waterproofing, does water need less frequent filtering from particles?

Yes, waterproofing seals the interior walls and stops dust and moisture entering. Water stays cleaner for longer, and routine cleaning becomes less frequent.

Does sea salt from the nearby port affect the waterproofing seal?

Modern waterproofing materials are safe from salt and sea humidity. But the tank concrete itself is vulnerable, and the seal protects it from further rust and deterioration.

Does a flat's tank sitting above a shop need different waterproofing?

The location does not change the sealing method, but if a shop sits below the tank any leak will damage stock and shopfittings. The waterproofing must be completely effective to prevent any moisture seepage.

Should residents be told after the shared tank has been sealed?

Yes, informing residents that the tank is now waterproofed and water is cleaner reassures them about cloudy water and explains why water quality improves immediately.
