Water tank waterproofing in Al Ajaweed, Jeddah

In Al Ajaweed, water tanks sit above mixed buildings where shops and flats share the same structure, and the tanks face a double burden: sea humidity from the nearby port and heavy diesel dust from port operations. A leak does not damage one home; it damages the shared walls, the ceiling of the shop below, and the flats simultaneously. Waterproofing protects the entire building frame from collapse.

Why tank waterproofing protects your water supply

Al Ajaweed sits on higher ground overlooking the Islamic Port and the industrial zone. Sea humidity keeps tanks perpetually damp, and diesel dust settles heavily on all exposed surfaces and into any opening.

Seal before a leak develops

In Al Ajaweed, tanks top mixed buildings, so a leak damages the shop and residential units together; waterproofing protects the entire structure from deterioration and protects all the business and homes that depend on it.
Repair an existing slow drip

Slow drips turn the tank into a breeding ground for algae and bacteria because sea humidity is constant. Deep cleaning before sealing removes all the contaminated surfaces down to bare concrete.
Keep drinking water free of debris

Heat expansion in Al Ajaweed is harshest in summer because humidity puts extra pressure on materials. Flexible waterproofing layers distribute that pressure and prevent new cracks from forming.
Reduce maintenance over time

An old tank serving mixed uses in Al Ajaweed may be weaker than those in villa districts. Resealing stops further decay and extends the tank's life by several more years before replacement becomes necessary.

What changes about water tank waterproofing in Al Ajaweed

Tanks in Al Ajaweed retain persistent moisture from the port's proximity and the sea. Cracks appear far faster here than in inland districts because the damp never fully releases from the concrete. For the whole method, see water tank waterproofing in detail.

The first reason
Shared structural load across mixed uses

A single tank in a mixed building serves commercial space below and residential units above. A leak immediately damages shared ceilings, internal walls of the shop, and the flats. Waterproofing protects the entire structure because it is one building with one ceiling, not separate homes. The cost of a leak is multiplied across all the units it serves.
The second reason
Constant sea humidity holds moisture

Al Ajaweed is close to the port and the sea, so humidity never dries completely from tank walls even in summer heat. Standard repair materials weaken quickly under this constant exposure. Composite waterproofing layers stop the leak and protect against the steady dampness that will return.
The third reason
Heavy diesel and metal dust settles fast

Port and factory dust settles thickly on all exposed surfaces including tank tops. This dust carries diesel residue and metal filings that work into small cracks and carry contamination into stored water. Deep cleaning before sealing removes this layer entirely so no pollutants remain trapped inside.

The character of Al Ajaweed

Mixed district: shops at street level with homes above them

Mixed district means one tank may serve a shop, a flat and possibly an office on different levels. A leak does not affect one home; it damages multiple investments, so waterproofing protects the asset value of the entire building from deterioration.

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 a leak in my tank damage the shop below me?

Yes, directly. Mixed buildings in Al Ajaweed share the same structure. A leak comes down through the ceiling and damages stock, equipment and fittings in the shop. The waterproofing protects both the shop and the residential units from loss and business interruption.

Why does my tank stay damp every single day?

Al Ajaweed has very high sea humidity because of the port's closeness. Damp air enters through any crack and keeps tank walls wet all the time. Waterproofing seals these cracks so humid air cannot reach the interior surface.

Does port dust actually contaminate drinking water?

Yes. Diesel dust and metal filings enter through cracks and settle inside as a thick grey silt. Moisture turns this into a paste that coats the bottom. Deep cleaning and sealing remove this contamination and prevent it from returning.

How often do tanks need resealing in a busy district like this?

High humidity and heavy dust mean tanks here need inspection every year. Good waterproofing lasts for years, but annual checks confirm that no moisture is entering again and that the seal is holding.

Can you waterproof the tank without emptying it completely?

No. Deep cleaning is essential. Tank walls must dry completely before waterproofing can bond. Draining, cleaning and thorough drying takes time, but it stops algae and bacteria from growing inside.

Does waterproofing stop moisture entering from the base?

Interior waterproofing protects against moisture entering through walls and roof. Moisture rising from the ground needs separate drainage. The team inspects the tank base and treats it if needed before sealing the walls.
