Water tank waterproofing in Al Marsa, Jeddah
Al Marsa is a subdivision at far south Jeddah near the coast, in its earliest development stages. New tanks in this district face construction dust from ongoing building on one side and sea salt and moisture from the coastal location on the other.
- Interior surfaces fully sealed
- Food-safe coating materials
- Cracks and gaps filled first
- Inspected before handover
Why tank waterproofing protects your water supply
A subdivision at far south Jeddah toward the coast within an outlying cluster of new districts, with no mosques, schools or named local roads yet shown on maps as development continues.
-
Seal before a leak develops
Construction dust from the active subdivision enters tanks through uncovered roofs, and waterproofing stops this inflow and protects against years of accumulated building pollution.
-
Repair an existing slow drip
Cleaning existing building dust, salt and coastal moisture is necessary before waterproofing because these contaminants can reduce how well sealing material adheres to tank walls.
-
Keep drinking water free of debris
Thermal expansion from summer sun may be limited because coastal moisture keeps concrete damp year round, but ground movement in the emerging subdivision requires flexible waterproofing.
-
Reduce maintenance over time
Resealing may be necessary every six to eight years in Al Marsa due to continuous salt, coastal humidity and ongoing construction stress around the tanks.

What changes about water tank waterproofing in Al Marsa
New tanks in Al Marsa face both construction dust from active building and sea salt and moisture from close proximity to the coast. For the whole method, see how we approach water tank waterproofing.
-
The first reason
Construction dust and sea salt together contaminate water
Al Marsa is new and under active construction near the coast. Fine construction dust from exposed roofs enters tanks, whilst sea salt and moisture seep in from outside simultaneously.
-
The second reason
Building continues for years in an emerging subdivision
The subdivision is in its early stages and construction will continue for many years. Your tank will be exposed to building dust for a long time, and early waterproofing protects against this sustained exposure.
-
The third reason
Coastal location multiplies humidity and salt stress
Nearness to the coast means high humidity and salt laden winds. These conditions weaken new concrete from outside and increase the need for tank waterproofing from the start.

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.

Questions worth asking first
Yes, active building releases fine dust that enters tanks from exposed roofs, and sea salt penetrates from outside. Waterproofing protects against both types of contamination simultaneously.
Before moving in, even before the tank's first fill with water. An emerging subdivision means construction dust will continue entering for years, and early sealing prevents prolonged exposure.
No, delaying means construction dust will accumulate inside the tank. The sooner you seal it, the fewer years of contamination exposure your water faces.
Modern waterproofing materials resist salt and high humidity. However, salt weakens concrete externally, and waterproofing stops salt from penetrating the tank interior.
The method is identical, but the need is more urgent and immediate in new locations. A new tank may need very early waterproofing before any contamination enters.
Fully drain the tank and clean construction dust and sea salt from inside with a dry brush and water. Ventilation for several hours is essential because coastal humidity is very high.
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 Al Marsa.
The duration depends on the tank size and how long the interior needs to dry before coating.
No special preparation is needed on the household's side.
