Water tank waterproofing in Namar, Riyadh

Namar is a long mixed district in the west running alongside Wadi Namar, where residents live between the dam lake and public gardens and parks. Tanks here face dampness from a nearby wadi and high lateral groundwater pressure, and pale limestone dust from the Tuwaiq plateau settles constantly on exposed surfaces.

Why a tank needs sealing, not patching

  • Water you store stays stored

    A lined tank keeps the water it holds instead of feeding a slow leak into the slab.

  • The damp stain has a cause

    The wet patch on the ceiling or wall below a tank is the symptom, and the tank is usually the cause.

  • Safe to hold drinking water

    The materials we apply are rated for potable water, so the tank is safe to drink from once it is back in use.

  • Proven before you rely on it

    We do not hand a tank back on trust.

Why the job is different in Namar

Tanks near the gardens and lake here seep from the base more because groundwater presses on tank walls from below and from the sides. The whole method is set out in the details of our water tank waterproofing service.

  • High groundwater pressure from below

    Namar lies near Wadi Namar and the lake, and groundwater here is very high. Pressure from water below the tank affects the foundation walls with force, and tiny cracks open because of this continuous lateral pressure.

  • Dampness from the wadi and nearby gardens

    Wadi Namar, the lake and gardens so close mean the soil around every tank stays damp most of the year. Moisture seeps slowly from the buried walls, and complete drying before sealing is hard in this environment.

  • Pale limestone dust and surface buildup

    Westerly winds from Tuwaiq carry pale limestone dust that settles on every surface in Namar. Exposed tanks accumulate thick layers of dust and debris, and cleaning before sealing takes extra care here.

What's Included

The district sits on the bank of Wadi Namar with the dam lake and public gardens very close by. Groundwater is high here and the ground slopes toward the wadi, meaning soil dampness surrounds all tanks.

  • Emptied and fully dried

    Draining may be difficult if groundwater is high, so we may need pumps to remove groundwater around the tank before complete drainage and preparation.

  • Cracks and leak points surveyed

    Cracks usually appear in buried walls where groundwater presses, so we inspect these carefully from both inside and outside.

  • Surface prepared before coating

    The surface may be covered in pale limestone dust and silt from seasonal dampness, so we clean it carefully and may need extra drying time.

  • Waterproofing applied in coats

    Hot weather and high humidity from the wadi require strong multi-layer sealing that protects against lateral pressure.

  • Full curing time

    Curing in a damp environment takes longer than in dry zones, so we recommend waiting three full days before the tank is refilled to capacity.

  • Fill test before handover

    Testing before handover confirms the tank can withstand groundwater pressure and seasonal dampness.

The character of Namar

Mixed district: shops at street level with homes above them

A mixed district near the wadi and gardens means tanks under high lateral groundwater pressure and seasonal dampness. Internal sealing protects against this pressure and stops water loss even when groundwater is high around the tank base.

What is different about West Riyadh

West Riyadh sits against the Tuwaiq escarpment, with Wadi Hanifah and Wadi Laban cutting through it. Irqah, Dhahrat Laban, Tuwaiq, Al Uraija and Al Suwaidi are mainly villas and low apartment buildings on sloping ground, while the Diplomatic Quarter keeps its mature landscaping and stone facades, and Dirab and the wadi floor still hold farms and rest houses. Westerly winds bring a pale limestone dust off the plateau that settles in courtyards, on window ledges and on outdoor furniture, and the farms and unpaved edges add soil and pollen through much of the year.

Questions before booking

Does high groundwater weaken the tank from underneath?
Yes, lateral groundwater pressure from below opens cracks in buried tank walls. Internal sealing stops pressure from inside the tank, and protecting the outer wall may need extra drainage channels around the base.

Does Al Shoaib Garden nearby affect water quality inside?
Gardens retain dampness around tanks, but full internal sealing protects the water from leakage and contamination. Stored water stays safe as long as the tank is fully sealed.

Should drainage be added around the tank before sealing?
In Namar, we may recommend extra drainage around the tank if groundwater is very high. This reduces pressure on tank walls and improves surface drying before sealing is applied.

How often should a tank near the wadi and lake be inspected?
Tanks beside wadis and lakes need inspection every six months at minimum. Seasonal dampness and groundwater pressure mean regular monitoring is necessary.

Does pale limestone dust from the plateau harm the seal after application?
Limestone dust may settle on the surface after sealing, but does not weaken the material itself. Regular cleaning of the tank exterior keeps it clear for easy inspection.

What if an old tank sits on sloping ground in this zone?
Old tanks on sloped ground may need thorough inspection before sealing. The slope means groundwater pressure is greater on one side, so we plan the sealing based on the survey.

How much does water tank waterproofing in Namar cost?
It is set after we have seen the job, because the price follows the size of the place, its condition and the time the work takes. Send a photo and a description on WhatsApp and we will give you an estimate before we reach Namar.
