Water tank waterproofing in Al Qawzain, Jeddah

Al Qawzain is a small coastal strip at the southernmost edge of Jeddah on the Southern Corniche, in a harsh marine environment. High salt content and moisture accelerate tank deterioration, and waterproofing protects against leaks and metal corrosion from coastal exposure.

Why tank waterproofing protects your water supply

An exposed coastal location on the Southern Corniche near Al Seef Beach, with a sewage treatment works and an iron factory nearby, in direct exposure to sea wind and salt spray.

Seal before a leak develops

Salt and coastal humidity cause accelerated crack formation, and waterproofing prevents leaks that damage the ceiling and building structure.
Repair an existing slow drip

Addressing tank leaks is urgent before salt penetration damages the water supply.
Keep drinking water free of debris

Salt contaminates water very rapidly, and sealing preserves water quality despite the harsh coastal environment.
Reduce maintenance over time

Renewing an old tank with waterproofing rather than replacing it makes sense in a coastal zone, since a new tank would face identical salt and humidity exposure.

What changes about water tank waterproofing in Al Qawzain

Sea salt deposits on all metal and concrete surfaces rapidly, and heavy night humidity prevents surfaces from drying, accelerating ongoing corrosion. For the whole method, see our water tank waterproofing service.

The first reason
Sea salt penetrates tank walls with accelerating speed

In this harsh coastal environment, fine salt particles penetrate cracks and small openings very rapidly. This contaminates the water with a saline taste, and accelerates decay of concrete and metal components.
The second reason
High night humidity keeps corrosion working continuously

Damp marine air and heavy night dew prevent concrete surfaces from drying out. This continuous corrosion creates new cracks that allow salt water and moisture to enter.
The third reason
Proximity to factory and treatment works adds additional pollutants

The nearby treatment facility and foundry add extra pollutants on top of salt and humidity. Waterproofing protects the tank against all of these contaminants combined.

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 sea salt and road dust affect the tank together?

Yes, salt penetrates cracks while dust settles on surfaces. Together they accelerate deterioration rapidly. Waterproofing protects against both.

Does seawater actually enter the tank through small cracks?

Yes, fine salt-water particles penetrate cracks easily. Waterproofing seals these pathways completely and prevents salt ingress.

How much protection does waterproofing offer in this harsh coastal environment?

The protection is very substantial. Materials are specifically tested in harsh coastal environments and withstand salt spray and high humidity.

Does a tank in a coastal area need different waterproofing than inland?

Yes, materials here must withstand salt and high humidity together. The sealing is specifically chosen for marine environments.

Do residents notice the difference in water quality after waterproofing?

Yes, the difference is very clear. Water becomes noticeably clearer and free from saline taste and musty smells.

How often must the tank be re-waterproofed in this coastal location?

Inspection every six months is strongly recommended. Complete re-waterproofing is typically needed every three to four years due to the harsh environment.
