Water tank waterproofing in Al Mahamid, Jeddah

Al Mahamid is an unplanned low-rise district on the eastern edge of Jeddah beside Old Makkah Road, with informal construction, unpaved streets and ageing drainage. Tanks here face unique challenges from soil moisture and contamination from old sewerage and dust from earth roads.

Why tank waterproofing protects your water supply

The district sits between Harazat Road and Old Makkah Road, with damp ground from old drainage networks and unplanned development. House foundations are shallow and moisture rises easily to rooftops.

Seal before a leak develops

Tanks in Al Mahamid may need structural assessment first because the building itself may need foundation repair.
Repair an existing slow drip

If basal seeping is severe, rising damp treatment from the soil may be needed before tank waterproofing.
Keep drinking water free of debris

Tank cleaning to remove clay and organic pollutants must be thorough before sealing application.
Reduce maintenance over time

After waterproofing, the tank is protected from rising moisture and external pollutants, and water becomes clean and safe.

What changes about water tank waterproofing in Al Mahamid

Tanks in Al Mahamid are old and installed on weak buildings, and most seeping originates from below, not above. Rising moisture from soil and ancient drainage is the primary problem. For the whole method, see the full water tank waterproofing page.

The first reason
Rising moisture from old unsealed drainage causes basal seeping

Old and unsealed drainage networks allow moisture to seep into soil around foundations. This moisture rises through old concrete structures to the rooftop. Tanks sit under constant upward moisture pressure.
The second reason
Unpaved earth roads deposit wet clay and heavy dust

Unpaved streets in Al Mahamid send wet clay when damp and heavy dust when dry. This wet clay settles on roofs and enters cracks easily, contaminating water with organic matter and silt.
The third reason
Weak old buildings with shallow foundations cannot resist rising damp

Informal construction and old weak buildings with shallow foundations cannot resist rising moisture pressure. Tanks on these structures seep even without visible cracks.

The character of Al Mahamid

Mixed district: shops at street level with homes above them

Mixed unplanned housing means shops and homes together, but the core problem here is weak structure and old drainage. This affects the tank from below, not from above.

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 East Jeddah

East Jeddah sits against the foothills, beyond the Haramain expressway and the ring roads, and it is where the city meets the desert edge. Apartment districts such as Al Safa and Al Naseem give way to villa areas and to new schemes still being graded out of bare ground. Dust here is the main story: fine desert sand on the spring and autumn winds, and grit from plots under construction. Some districts lie on the wadi lines that drain the hills, so a winter storm leaves mud on the streets that dries to powder.

Questions worth asking first

Why does seeping in Al Mahamid always originate from the tank base?

Rising moisture from soil and old drainage pressurises the tank base. Shallow foundations cannot stop it, and seeping comes from below.

Does clay from unpaved roads contaminate the tank quickly?

Yes. Wet clay settles on the roof and enters cracks. Organic pollutants from clay discolour water and cause unusual odour.

Is tank cleaning alone sufficient against rising ground moisture?

Cleaning alone does not solve the problem. Moisture from below will return immediately. Waterproofing is the only way to stop rising damp.

Should a tank in a reorganisation zone undergo structural survey first?

Yes. If the building is very weak, foundation repair may be needed before tank waterproofing. A quick assessment is important.

Do shared drainage networks affect tank water quality?

Yes. Old shared drainage leaks to the soil and raises moisture under all homes. All tanks here face the same problem equally.

What should I arrange before the waterproofing team arrives?

Empty and completely dry the tank. Alert the team to seeping from the base and any structural problems you have noticed in the building.
