Water tank waterproofing in Prince Fawaz South, Jeddah

Prince Fawaz South is a densely built extension in south Jeddah, close to roads built for lorry traffic serving the Islamic Port and industrial city. Rooftop tanks here accumulate grey dust heavy with diesel and metal filings, and sea humidity from the port keeps them perpetually damp.

Why tank waterproofing protects your water supply

The district lies on heavily used routes for port and factory traffic. Dust settling here is grey and oily with diesel and metal particles, not the pale sand of outlying areas or the fine desert grit of the east.

Seal before a leak develops

Hairline cracks in Prince Fawaz South tanks trap heavy oily dust that prevents them drying; waterproofing seals them and stops ongoing concrete degradation.
Repair an existing slow drip

Algae and fungi colonise tanks rapidly in high humidity and accumulated pollution; waterproofing blocks moisture ingress that these organisms depend on.
Keep drinking water free of debris

Extreme summer heat and winter moisture create stress in aged concrete structures; waterproofing protects against new cracks forming at weakened points.
Reduce maintenance over time

Older tanks in this district serve for additional years after strong waterproofing rather than requiring replacement.

What changes about water tank waterproofing in Prince Fawaz South

Tanks here coat themselves with oily grey dust far faster than districts distant from the port, a residue that differs completely from the dust accumulated elsewhere in Jeddah. For the whole method, see how we approach water tank waterproofing.

The first reason
Industrial dust is heavy, oily and adhesive

Diesel exhaust and metal filings from lorries and workshops settle on the roof as a thick, greasy layer. This dust enters hairline cracks and leaves the tank walls perpetually damp. Waterproofing seals the cracks and prevents dust accumulation inside.
The second reason
Persistent port humidity weakens concrete throughout the day

Sea air from the Islamic Port maintains high humidity on all rooftop surfaces in this sector. This keeps tank walls damp around the clock. Sustained moisture accelerates concrete decay and feeds algae and fungal colonies.
The third reason
Older concrete buildings here have accumulated stress cracks

Most structures in this district are aged concrete with flat roofs and open stairwells that collect dust. Decades of loadbearing and environmental exposure have created networks of hairline fractures. These routes allow water, humidity and pollutants to enter together.

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

Does diesel soot cause health risks in drinking water?

Diesel exhaust residue and metal particulates do change the taste of water and may carry contaminants. Waterproofing prevents these pollutants from entering the tank in the first place.

Will port humidity damage the waterproofing after completion?

No. The materials used are engineered for high humidity and coastal industrial environments. All coatings dry completely inside the sealed tank before refilling begins.

Can microscopic metal particles enter an unsealed tank?

Yes. Minute metal dust particles from factories and heavy vehicles enter through hairline cracks, accumulating inside. Waterproofing stops this contamination at the source.

Do older buildings in this district need stronger waterproofing?

Older tanks usually carry more stress cracks from age. The team assesses the tank condition first and selects materials suited to its state and location.

Does heavy lorry traffic affect how the seal hardens?

No. Vibrations from passing traffic do not affect the dried seal inside the closed tank after it has cured completely.

When can the tank be refilled after sealing in this humid area?

The tank is refilled after complete curing of the seal, following the same timeline as any district. High humidity does not accelerate drying.
