Water tank waterproofing

Water tank waterproofing in Wadi Qaws, Jeddah

Wadi Qaws is a valley running down from the Jabal Khashash range east of Jeddah towards the coast, whose name is borne by the neighbouring area with resthouses and open plots rather than dense building. The Wadi Qaws dam protects eastern districts from flood. Tanks here sit on scattered homes amid open space. Seasonal moisture from the dam and winter rains affect the tanks. Waterproofing guards against moisture entry and light dust from the wadi.

Why tank waterproofing protects your water supply

An open rural area on the Wadi Qaws valley draining down from Jabal Khashash, with scattered homes, resthouses and flat open ground. A dam on the wadi. Seasonal moisture from potential flood and winter rainfall.

  • Seal before a leak develops

    Tanks in Wadi Qaws close to the dam and wadi endure high seasonal moisture and possible flood, so cracks develop quickly in the rainy season.

  • Repair an existing slow drip

    A leak from a tank in a damp rural area enters the foundation and soil and causes permanent house dampness.

  • Keep drinking water free of debris

    Water from an unsealed tank in Wadi Qaws carries moisture and dust, but not industrial pollutants. Basic cleanliness is protection against moisture.

  • Reduce maintenance over time

    Renewing an old tank in Wadi Qaws with comprehensive waterproofing ensures the tank survives seasonal cycles and potential floods, better than replacement.

What changes about water tank waterproofing in Wadi Qaws

Tanks in Wadi Qaws endure high seasonal humidity from rain and flood water, and remain damp because the area sits close to the wadi bed. For the whole method, see our water tank waterproofing service.

  • The first reason

    High seasonal moisture from rain, flood and the dam

    The dam on the wadi provides protection but traps water and moisture. Rainy season brings heavy water into the wadi and humidity rises in the air. Tanks beside the wadi stay damp almost year round. Moisture penetrates concrete and opens cracks quickly. Waterproofing seals walls and protects against relentless dampness.

  • The second reason

    Clay wet ground beneath houses and tanks

    Land around the wadi is clay soil, wet especially after rain. This moisture rises into house foundations and tank bases. Weak foundations cause uneven subsidence and the tank cracks under pressure. Waterproofing protects the tank body but the foundation may need support.

  • The third reason

    Light fine dust from the wadi and earth roads

    Wadi Qaws is a rural zone with earth roads. Dust here is light and fine and easy to clean. But moisture makes dust stick to the tank body. A tank in a rural district like this does not need protection from heavy industrial dust, but it does need protection from constant moisture.

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

Possibly, if the ground is very wet and the foundation is weak. Water from beneath the tank may enter the foundation and cause uneven settling. Foundation inspection is essential before waterproofing.

At least twice. The first cleaning removes light dust and moisture. The second dries the tank completely before waterproofing begins.

Yes, at least every six months. Seasonal moisture means we monitor the tank condition.

Yes, completely. The rural area is far from industrial pollutants. Water after waterproofing is safe and healthy.

If the foundation is sound, no correction is needed. But if there is obvious settling or cracks in the foundation, it should be reinforced before waterproofing.

We work in any season but dry season is better. High moisture from rain affects drying and waterproofing times.

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 Qaws.

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.
