Water tank waterproofing in Al Sahl, Jeddah

Al Sahl is a low density locality in south eastern Jeddah beside the wider Bahrah area, reached via Al Rakb Street off the Jeddah Makkah Expressway. The area mixes villas, chalets and flats, and tanks here sit away from industrial zones but close to a high water table. Constant groundwater pressure and slow seepage damage tanks steadily. Early waterproofing stops this pressure before the tank fails.

Why tank waterproofing protects your water supply

Al Sahl sits within the wider Bahrah locality of south eastern Jeddah. Building is light density with gardens and space between homes, and the groundwater table here is relatively high and affects underground cisterns.

Seal before a leak develops

Al Sahl tanks seep slowly from all directions due to groundwater pressure, and moisture gradually enters the concrete walls from the outside.
Repair an existing slow drip

Seepage from outward hydrostatic pressure happens slowly but constantly, and waterproofing stops it from day one.
Keep drinking water free of debris

Summer heat dries the tank interior while winter groundwater pressure increases, and the seal handles this endless cycle of stress and seasonal change.
Reduce maintenance over time

The tank in Al Sahl could become unusable if seepage continues unchecked, and early waterproofing preserves it for many more decades of service.

What changes about water tank waterproofing in Al Sahl

Al Sahl tanks hold moisture longer than other districts because of high groundwater. Slow seeping occurs even in tanks that show no visible cracks from inside. For the whole method, see water tank waterproofing in detail.

The first reason
High groundwater exerts pressure on all tank walls

Al Sahl sits in a relatively low area, and the water table is close to the surface. Outward water pressure squeezes groundwater into the tank through tiny cracks invisible from inside, and waterproofing stops this ingress completely.
The second reason
Underground tanks stay permanently damp on the outside

Garden tanks in Al Sahl are surrounded by persistent soil moisture. This damp weakens concrete and speeds deterioration, and waterproofing protects the walls from outside moisture and constant hydrostatic pressure.
The third reason
Mineral deposits accumulate in water from groundwater seepage

Groundwater carries dissolved minerals, calcium and iron which settle in the tank and cloud the water. Cracks allow groundwater to seep directly in, and waterproofing stops this contamination at the source.

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.

Questions worth asking first

Does groundwater affect the tank even after waterproofing is finished?

Groundwater cannot enter the tank after waterproofing. The outward pressure from groundwater remains, but the seal stops water and minerals entering the tank interior.

Does an underground tank in an Al Sahl garden need different sealing?

Yes, underground tanks face constant groundwater pressure from every direction. Waterproofing must be very strong to stop water entering through cracks and micropores on all sides.

After waterproofing, does the water need less frequent cleaning from mineral deposits?

Yes, new groundwater cannot enter after sealing. Old deposits remain but no new minerals seep in, so the water becomes cleaner quickly and stays clean.

Do winter rains and seasonal floods affect the waterproofing seal here?

Winter rains are rare in Al Sahl, but seasonal groundwater rise may increase hydrostatic pressure. Good waterproofing withstands this extra pressure and remains unaffected.

Should waterproofing be delayed while the locality continues to develop?

No, delay only allows more seepage and deterioration. Early waterproofing protects the tank now and extends its lifespan, and postponement only increases damage.

After the job is done, how long before the tank needs routine inspection?

The seal lasts many years without renewal if the tank remains sound. Inspection one year after completion is standard, and the coating needs checking again every two years after that.

How much does water tank waterproofing in Al Sahl 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 Al Sahl.
