Water tank waterproofing in Al Majami, Jeddah

Al Majami is a new villa district in the Obhur Al Shamaliyah extension north of Jeddah, where every house has its own rooftop tank. Direct sun exposure and extreme heat cause repeated thermal expansion that cracks tank walls over time.

Why tank waterproofing protects your water supply

The district sits on open ground with no shade from neighbouring buildings, meaning tanks face direct sun all day and experience large temperature swings between night and day.

Seal before a leak develops

Large villa tanks need careful assessment of existing cracks before sealing begins, as thermal stress may have caused cumulative damage over years.
Repair an existing slow drip

If seeping appears at the tank base, this signals deep cracks and waterproofing may need additional measures to seal at depth.
Keep drinking water free of debris

Soil moisture from the garden may require external sealing as well in some cases, not only internal protection.
Reduce maintenance over time

After waterproofing, the tank stays protected for years if sealed properly, and annual checks are sufficient for maintenance.

What changes about water tank waterproofing in Al Majami

Tanks in Al Majami are usually large and deep, bearing heavy water loads on walls that may be comparatively thin. Extreme heat accelerates cracking in these oversized tanks. For the whole method, see our water tank waterproofing service.

The first reason
Intense heat causes repeated expansion that splits walls

In Al Majami, tanks have no shade whatsoever, and the temperature difference between tank interior and exterior reaches 20 degrees Celsius or more. This causes recurring stress on concrete walls that produces microscopic cracks that widen over time.
The second reason
Cool nights cause damp to seep into expansion cracks

Cool nights cause moisture to condense on the tank, and the cracks created by thermal stress become pathways for seeping. Without waterproofing this cycle repeats daily and widens the fissures.
The third reason
Garden watering and irrigation raise soil moisture around the tank

Villas have landscaped plots and irrigation systems, and moisture from the garden soil rises toward the rooftop. This increases outward pressure on tank walls, accelerating seeping if cracks are present.

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 Majami

Villa district: private plots, gardens and a boundary wall to every house

Villa housing means each tank is private and entirely your responsibility, with no shared arrangement with neighbours. This gives you flexibility in choosing when to seal, and you bear the consequences alone if a leak develops from delay.

Questions worth asking first

Does thermal stress create new cracks every hot season?

Yes. In Al Majami the daily temperature swings cause repeated stress on concrete. Small cracks widen, and new ones may appear each severe heat period.

Can seeping from the garden soil reach the tank?

Yes. Soil moisture from watering rises through the concrete structure to the rooftop. If the tank has cracks, moisture will seep in from outside.

When is the best time to seal a villa tank in Al Majami?

Late winter or early spring is ideal, before intense heat arrives. This allows waterproofing materials to cure before facing severe thermal stress.

Should I wait before waterproofing a new build tank?

It is wise to wait 3 to 6 months after construction so the concrete fully cures. Then waterproofing protects the tank from future cracking.

Do larger tanks need stronger waterproofing?

Yes. Larger tanks carry greater water weight and need robust sealing. The walls may be thinner relative to size, making protection more critical.

What should I prepare before the waterproofing team arrives?

Empty and completely dry the tank. Ensure the rooftop is easily accessible, and tell the team if there is a current leak or visible cracks.
