Water tank waterproofing in Al Sahel, Jeddah

Al Sahel sits on the Red Sea coast where high humidity and salty air attack the tank throughout the year. The tank's inner walls face constant sea moisture and salt-laden air that seeps in and accumulates, speeding deterioration and leaks far faster than inland districts experience.

Why tank waterproofing protects your water supply

The location near Al Saif Corniche and Jeddah Islamic Port means persistent sea humidity and salt-saturated air affecting the tank throughout the calendar year without seasonal relief.

Seal before a leak develops

In this coastal location, salt and humidity penetrate concrete faster, so closing fine cracks becomes urgent before damage spreads and reaches the structural steel beneath.
Repair an existing slow drip

Persistent sea humidity slows tank drying after cleaning, and waterproofing must be applied to a completely dry surface or the seal will not bond properly to the walls.
Keep drinking water free of debris

Salt clouds the water and makes it unfit to drink, and waterproofing stops new salt entering while keeping the water supply clean and safe throughout the year.
Reduce maintenance over time

Coastal tanks need more frequent inspection and maintenance, but a strong waterproofing seal cuts the need for repeat cleaning and repairs during the years ahead.

What changes about water tank waterproofing in Al Sahel

Tanks here face moisture pressure far stronger than inland areas, and salt deposits build up on walls rapidly even during the dry season when other districts see minimal change. For the whole method, see the full water tank waterproofing page.

The first reason
Salt and humidity accelerate concrete breakdown

Salty air from the sea penetrates concrete pores and exposed metals, while constant high humidity prevents the natural drying that slows damage elsewhere. The result is leaking years sooner and interior corrosion that inland tanks do not experience at the same rate.
The second reason
Salt crust forms on the interior walls

When salty water evaporates inside the tank, it leaves white salt deposits coating the walls. This makes the water taste brackish and appear cloudy. Waterproofing stops new salt from entering and keeps the water clean and clear.
The third reason
Protection from sea winds and salt spray

Coastal winds carry salt spray that settles on roof surfaces and openings, and waterproofing protects the tank from salt entering through fine cracks and gaps in the walls and lid that sea mist would otherwise penetrate.

The character of Al Sahel

Coastal area: high humidity and salt air through the year

Constant high humidity and salty air mean the tank walls need robust waterproofing protection. Salt deposits build rapidly on wet concrete surfaces, and waterproofing stops that accumulation and preserves drinking water that remains clean and safe.

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 salty water enter the tank from seawater below ground or from salt air above?

Salt enters mainly from the air through fine cracks and gaps in the tank walls and lid. Coastal winds carry salt spray year round, and the high humidity accelerates salt penetration. Groundwater does not reach the tank unless the building foundation is severely damaged.

How often should a coastal tank be inspected after waterproofing is complete?

Inland tanks need annual inspection, but here in Al Sahel we recommend inspection every six months to ensure the waterproofing coat continues to shield the walls from constant salt and moisture exposure.

Can waterproofing be applied when the tank sits directly exposed to ocean winds?

Yes, but after waterproofing the openings and lid must be checked regularly, as strong winds can stress seals if they are not perfectly tight. A well-sealed tank resists salt air even under direct wind exposure.

Does green algae in a coastal tank mean salt water has already contaminated it?

Algae grows from high humidity and sunlight, not directly from salt. However, algae is a sign the tank walls are unprotected, and salt may well be present alongside it and entering at the same rate.

After waterproofing, does salt deposition on the walls stop completely?

Yes, waterproofing blocks salt entry through cracks. Water that is already salty requires drainage and cleaning before sealing, and after that, fresh water stays salt free from new deposits.

Does high sea humidity mean the waterproofing coating will fail faster here?

Properly applied waterproofing resists high humidity for years, but regular inspection matters more here than inland. Humidity does not degrade the seal if it is tight and installed correctly on a completely dry surface.
