Water tank waterproofing in Al Corniche, Jeddah

Al Corniche is a northern seafront stretch overlooking resorts and hotels, where high humidity and salt air penetrate tank walls throughout the year. Waterproofing seals the cracks before moisture turns into a continuous corrosion cycle in the reinforcement and concrete structure.

Why tank waterproofing protects your water supply

Direct location on the Red Sea coast means constant humidity and concentrated salt in the air, with the strongest effect on the water tanks that sit high on roofs above the sea.

Seal before a leak develops

In Al Corniche leaks develop rapidly from the daily salt and humidity cycle, so waterproofing protects foundations from saline moisture that causes extremely fast corrosion of concrete and reinforcement.
Repair an existing slow drip

Old tanks in Al Corniche need very deep cleaning to remove crystallised salt before waterproofing, to prevent corrosion continuing beneath the new seal.
Keep drinking water free of debris

Thermal expansion combined with salt causes faster cracking in Al Corniche, so waterproofing provides dual protection against both salt penetration and thermal stress.
Reduce maintenance over time

Even an older tank can last several more years after quality waterproofing in Al Corniche, rather than full replacement which is extremely expensive in a beachfront location.

What changes about water tank waterproofing in Al Corniche

On Al Corniche night humidity stays on tanks until mid-morning, and salt crystallises and eats concrete three times faster than in inland neighbourhoods, requiring more frequent maintenance. For the whole method, see the full water tank waterproofing page.

The first reason
The salt and humidity cycle works every night and every day

At night salt-laden humidity condenses on both the outer and inner surfaces of the tank walls, penetrating hairline cracks. During the day summer heat dries only the outside surface, but salt leaves crystals inside the concrete that push outward. This cycle repeats daily without waterproofing.
The second reason
Salt accelerates reinforcement rust through multiple pathways

Salt penetrates cracks and reaches the embedded steel where it catalyses corrosion. Simultaneously, salt draws water from inside the concrete, widening pores and allowing more salt to enter. This chemical reaction causes extremely rapid rusting that spreads deeper each year.
The third reason
Concentrated moisture dries only partially even in summer

Extreme summer heat dries only the outer surface. The interior stays damp from humidity that condensed at night, keeping the reinforcement in a permanently wet environment. This accelerates rust even on the hottest days, unlike inland areas where moisture evaporates fully.

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.

The character of Al Corniche

Coastal area: high humidity and salt air through the year

The coastal location means salt and humidity work together every day and every night. Waterproofing creates a barrier between salt and concrete, stopping the daily corrosion cycle and protecting the reinforcement and pipes from extremely rapid rust.

Questions worth asking first

Does sea salt from coastal air actually enter tanks through cracks?

Yes. Salt evaporates from sea spray and crystallises inside tank cracks. This accelerates concrete and steel corrosion. Waterproofing seals the cracks so salt cannot enter from even the smallest opening.

Does salt affect the taste of the drinking water in Al Corniche?

If salt enters, water salinity may increase slightly. But the bigger problem is rust caused by salt, not taste. Waterproofing stops salt entering before it affects taste or safety.

Does salt from the tank corrode pipes and fittings very quickly?

Yes. Salt corrodes copper, bronze and mild steel rapidly. This can halve or worse the service life of piping. Waterproofing protects pipes by sealing the tank against salt entry.

Does night humidity combined with sea air cause extremely rapid rust in Al Corniche?

Yes, very much so. Salt and moisture together accelerate rust five times or more. In Al Corniche rust happens visibly fast even in new tanks without waterproofing.

How often should a tank in Al Corniche be inspected after waterproofing?

We recommend annual inspection in Al Corniche. Concentrated salt and humidity accelerate wear even after sealing. Regular checks prevent new problems developing.

Do new tanks in Al Corniche need waterproofing immediately or can it wait?

New tanks in Al Corniche should be waterproofed quickly. Salt and humidity begin affecting concrete and steel from year one. Waiting makes problems larger and more costly to solve later.

How much does water tank waterproofing in Al Corniche cost?
