Water tank waterproofing in Al Mahjar, Jeddah

Al Mahjar is a mixed-use district in South Jeddah near the port and industrial city where grey diesel-laden dust and metal filings constantly settle on rooftops. Waterproofing here prevents metal shavings, diesel residue and port pollutants from entering drinking water and corroding the tank structure and pipework.

Why tank waterproofing protects your water supply

A working industrial district adjacent to the Islamic Port and the industrial city, where lorry traffic runs through the day and night. Dust settling here is grey with diesel and metal particles rather than pale sand, and sea humidity keeps surfaces perpetually damp.

Seal before a leak develops

Heavy pollutants from the port enter the tank quickly, so early waterproofing protects both concrete and metal components from concurrent oxidation and structural failure.
Repair an existing slow drip

Slow seepage allows metal particles to accumulate at the tank bottom, whilst waterproofing prevents these contaminants entering from the beginning and keeps water clean.
Keep drinking water free of debris

Intense summer heat deepens cracks through thermal expansion cycles, and night humidity from the port accelerates corrosion, making waterproofing a practical necessity.
Reduce maintenance over time

An older tank in Al Mahjar may continue serving safely after waterproofing instead of replacement, provided the cracks remain surface-level and the concrete has not lost structural strength.

What changes about water tank waterproofing in Al Mahjar

Tanks here accumulate metal deposits and diesel residue much faster than quiet neighbourhoods, and the stored water needs additional filtration to remain safe for drinking. For the whole method, see water tank waterproofing in detail.

The first reason
Port and factory dust reaches the tank daily

The port and adjacent factories release grey dust containing metal shavings and diesel particles. This dust settles on the roof and enters the tank through cracks and gaps in the lid. Waterproofing seals these pathways and stops heavy industrial pollutants from contaminating the water supply and storage vessel.
The second reason
Port humidity accelerates cracks and seepage

Sea moisture from the port direction penetrates the concrete and deepens existing micro-fractures. Buildings here are mostly older concrete with flat open roofs, so humidity keeps them perpetually damp. Interior waterproofing cuts this pathway and shields the tank walls from progressive weakening and structural failure.
The third reason
Metals corrode from airborne port pollutants

Metal shavings and salts from the port enter the tank and cause rapid rust on pipes and reinforcement steel. The waterproofing coating creates a barrier that stops these particles before they reach the metal structures, extending equipment lifespan significantly.

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

Do port pollutants and transport dust actually enter water tanks in Al Mahjar?

Yes, metal shavings, diesel particles and industrial salts enter through fine cracks. Residents sometimes notice metallic deposits settling at the tank bottom. Waterproofing stops these pollutants at source before they contaminate the water supply.

Does port humidity make old tanks deteriorate much faster here?

Definitely. The high humidity from the port direction deepens existing cracks rapidly. A tank that might last ten years in a quiet area may fail in five years here due to continuous damp conditions and industrial pollutants.

When should I start worrying about water quality in Al Mahjar?

If you notice grey discolouration or a metallic smell, pollutants are definitely entering. Regular inspection catches the problem before contamination reaches unsafe levels.

Can the tank be sealed while port and factory activity continues nearby?

Yes, the team works efficiently even with continuous transport activity around the area. Coordination with the building owner ensures the team arrives at a suitable time to complete the work.

Does waterproofing protect pipes and steel reinforcement from rust?

Waterproofing stops pollutants and salt from entering, significantly reducing metal corrosion. However, if pipes have already rusted heavily, they may need replacement as sealing will not reverse existing damage.

How often should a tank in an industrial port area be inspected?

Annual inspection is sensible in Al Mahjar because pollutant levels are high. Regular checks catch any early damage to the waterproofing layer before it becomes a water quality problem.

How much does water tank waterproofing in Al Mahjar cost?

It is set after we see the job, because the price follows the kind of work, the size of the space, its condition and the time and materials it needs. Send a photo and a short description on WhatsApp and we will give you an estimate before we reach Al Mahjar.
