Water tank waterproofing in Al Murjan, Jeddah

Al Murjan is a small coastal district on the north corniche west of Al Basatin, with villas and low-rise apartments facing the sea, where sea breeze and salt spray blow constantly. Water tanks here corrode from outside as salt deposits etch the concrete, while high humidity inside accelerates algae blooms. The combination is lethal to unprotected tanks.

Why tank waterproofing protects your water supply

A small coastal district on the north corniche between King Abdulaziz Road and the sea, low density with villas, apartment buildings and gated compounds facing the waterfront, served by Al Murjan Street and north corniche road, with Al Murjan Mall at its centre.

Seal before a leak develops

In coastal zones, thorough inspection for salt corrosion damage on tank walls is essential before work, and existing cracks require special assessment for salt penetration depth.
Repair an existing slow drip

Tank cleaning in coastal areas must remove salt deposits as well as algae, and final rinsing must ensure all salt residue is gone before the tank is dried for coating application.
Keep drinking water free of debris

Salt and moisture together accelerate expansion and contraction cycles in tank concrete, so waterproofing prevents water and salt ions from penetrating stress cracks created by these cycles.
Reduce maintenance over time

Renewing a coastal tank with professional sealing extends its life substantially and protects against salt and moisture damage, avoiding the high cost of premature replacement.

What changes about water tank waterproofing in Al Murjan

In coastal areas, high humidity and salt air together accelerate external corrosion of tank walls and internal algae growth simultaneously, a double attack. For the whole method, see the full water tank waterproofing page.

The first reason
Sea wind and salt spray corrode tanks from the outside

Al Murjan sits on the corniche, and salt spray from waves blows constantly year-round. Salt deposits on the tank surface and penetrates small cracks, accelerating concrete deterioration from both outside and inside simultaneously. Corrosion spreads rapidly in this environment.
The second reason
Constant high humidity accelerates algae growth

In Al Murjan, humidity never drops below 70% even in the driest summers. This coastal climate creates ideal conditions for algae to bloom on tank interior walls rapidly, staining water green and creating odours within weeks of minor cracks appearing.
The third reason
Drinking water needs extra protection from coastal exposure

Households in Al Murjan use tanks for drinking, cooking and bathing, and salt spray plus high humidity can impart taste and odour to water even before visible algae forms. Professional waterproofing keeps internal surfaces pristine and water quality excellent.

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 West Jeddah

West Jeddah is the Corniche and the districts immediately behind it: a front line of glass towers and hotels on the waterfront, then older apartment streets and villa blocks inland. The building stock is a mix of ages, from concrete flats of the earlier expansion to new high rise on reclaimed ground. The sea wind is the constant here, carrying salt spray onto facades in every season and leaving a white bloom on rendered walls and a fog on glass. In humid summer months that film turns sticky and holds dust from the busy coastal road.

Questions worth asking first

Does sea salt from the water enter Al Murjan tank supplies?

Yes, salt deposits accumulate on the tank and enter through cracks, imparting a salty taste to water and accelerating concrete deterioration from inside and outside at once.

Does high humidity in Al Murjan cause algae blooms faster than inland?

Yes, far faster. Coastal humidity is relentless, creating perfect conditions for algae. Tanks here need algae cleaning far more frequently without waterproofing and may show visible growth in weeks.

What should be prepared before tank sealing in a coastal location?

Ensure safe rooftop access, drain the tank completely, and provide water for final rinsing after cleaning to remove all salt residue before the coating is applied.

Are metal tanks better than concrete in coastal areas?

Metal tanks may rust from salt and humidity. Concrete with professional waterproofing is superior because the coating protects against both salt penetration and moisture equally.

How often should a coastal tank be inspected after waterproofing?

Every six months is recommended for coastal locations, as salt spray and humidity may cause new damage to emerge faster than in sheltered districts.

Can a tank be sealed when exposed directly to ocean wind?

Yes, waterproofing protects against salt and humidity even with direct sea exposure. However, more frequent inspection is essential in this extreme environment to catch any damage early.
