Water tank waterproofing in Wadi Mareekh, Jeddah

Wadi Mareekh is an eastern district undergoing rapid expansion amid vacant plots and new schemes. Tanks here face double pressure from sea humidity reaching inland from the Islamic Port and industrial dust mixed with diesel and metal filings, which accelerates internal wall cracking. The weight of ongoing construction and transport activity adds vibration stress that existing concrete cannot absorb.

Why tank waterproofing protects your water supply

The area stretches along King Abdullah Feeder Road and Palestine Street, lying close to the Islamic Port and industrial city. Grey-toned dust heavy with diesel and metal residue settles rapidly on exposed surfaces and rooftops.

Seal before a leak develops

Moisture mixed with salt and industrial dust seeps into the building below the tank, particularly into older foundations and open ledges where concrete meets the rooftop structure.
Repair an existing slow drip

Slow leaks in new tanks begin from hairline cracks opened by heavy lorry vibrations and by the seasonal expansion and contraction cycle of exposed concrete.
Keep drinking water free of debris

Dust mixed with diesel and metal filings accumulates with water and forms a grey sediment that contaminates drinking water even without visible seepage, requiring filtration or tank cleaning.
Reduce maintenance over time

An older tank in an industrial area benefits more from waterproofing than replacement, because new pollutants will affect a replacement tank equally, so extending the life of the existing one is more practical.

What changes about water tank waterproofing in Wadi Mareekh

New tanks here often show their first cracks during the first year of operation due to the density of airborne pollutants and the frequency of moisture absorption and drying cycles. For the whole method, see what water tank waterproofing involves.

The first reason
Industrial dust speeds concrete fracturing

Dust mixed with diesel and metal filings settles on the tank and absorbs moisture. This wet mixture hardens on edges and cladding in summer, creating repeated pressure that deepens existing cracks and generates new ones. The cycle repeats with each humid dawn and dry afternoon.
The second reason
Ongoing construction shakes foundations

New residential and commercial schemes around the area mean continuous heavy lorries and building machinery. These vibrations travel through the ground and place additional stress on rooftop surfaces and the tanks standing on them, opening micro-fractures that widen with time.
The third reason
Coastal humidity causes continuous expansion and contraction

Sea air brings dampness at dawn and night, and dry summer heat draws it out. This repeated expansion and contraction fractures both new and older concrete, especially on exposed vacant plots. The effect accelerates when dust particles lodge in the pores and lock moisture inside.

The character of Wadi Mareekh

New development: ongoing construction and vacant plots between the homes

A neighbourhood in active development means both new and existing tanks under pressure from construction vibrations and airborne industrial contaminants. Waterproofing protects new tanks from early leaks and prevents old ones from deteriorating faster in this high-pollution environment.

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 industrial dust from the port area enter the tank before waterproofing starts?

Yes, dust mixed with diesel and metal filings settles on the surface and around the tank opening. Before sealing, the tank interior must be thoroughly cleaned of these heavy pollutants that accumulate with moisture and form a dense residue.

Can the tank be waterproofed while construction machinery and heavy traffic continues around it?

Yes, but vibrations from heavy equipment may affect the curing of waterproofing layers. It is better to schedule work during a quieter period, or to delay the first inspection until activity around the area decreases.

How often should a new tank be inspected in an industrial pollution setting?

New tanks in industrial areas should be inspected after the first year of waterproofing to confirm coating integrity, then every two years instead of the usual intervals.

Does salt from the port air penetrate through new waterproofing layers?

Salt alone does not penetrate a strong waterproofing coat, but moisture mixed with sea salts causes decay in microscopic voids if the seal is not completely watertight throughout.

Do rare rainfall and port pollutants mix inside the tank water?

Yes, rain sweeps dust and pollutants from the roof surface. If the tank collects roof runoff, the inlet and filter must be cleaned thoroughly before waterproofing begins.

Should an older tank in this newly developing area be replaced or can waterproofing work?

If concrete is sound and cracks are surface-level, waterproofing will work. However, in an industrial setting, the foundation and interior edges must first be inspected to rule out deep internal seepage.

How much does water tank waterproofing in Wadi Mareekh cost?

It is set after we see the job, because the price follows the kind of work, the size of the space, its condition and the time and materials it needs. Send a photo and a short description on WhatsApp and we will give you an estimate before we reach Wadi Mareekh.
