Water tank waterproofing in Al Wisham, Riyadh

Al Wisham is an older residential quarter in central Riyadh, mid-rise apartments with shops along its main streets. It sits south of Al Namudhajiyah and north of Umm Sulaim within Al Shumaisi municipality. Tanks here seep and seepage damages both the apartments and the shops. Drainage from the old building may be limited, and moisture pools around underground tanks. Waterproofing must stop the seepage before it spreads through old dense building.

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 Al Wisham

Tanks in Al Wisham seep from age and pressure. Seepage spreads fast through the dense old building. The whole method is set out in our water tank waterproofing guide.

  • Old tanks in dense building

    Al Wisham is dense and the tanks are old. Seepage from one tank may reach many flats and shops. Shared walls carry damp easily. Waterproofing must stop the leak at the source before it spreads.

  • Shops and apartments sharing the tank

    Shops and flats in Al Wisham may share one tank. Seepage damages the shop during trading and the flat at the same time. Pressure from heavy constant use opens cracks fast.

  • Old building and poor drainage

    Old building may not have enough drainage around foundations. Moisture pools around underground tanks. Inside sealing protects the tank from outside pressure and pooled water.

What's Included

Al Wisham is an older residential quarter in central Riyadh south of Al Namudhajiyah. Apartments with shops on main streets. Building is dense and underground tanks are surrounded by old foundations.

  • Emptied and fully dried

    Draining an old tank in dense building may be slow and access is limited.

  • Cracks and leak points surveyed

    Cracks in an old tank are numerous and may be deep; inspection must be close.

  • Surface prepared before coating

    The interior surface is fouled from years and hard water; cleaning takes real effort.

  • Waterproofing applied in coats

    Coats go on old walls that may be damp, so complete drying before application is essential.

  • Full curing time

    Curing may take longer because of surrounding moisture and dense building.

  • Fill test before handover

    Fill testing is cautious because the old tank may not handle full pressure fast.

Questions before booking

The tank is old and apartment and shop share it: who pays for sealing?
This is agreed between shop owner and flat owners. Both benefit. Many split costs. Check ownership papers to clarify responsibility.

The old building has poor drainage: does pooled water affect the waterproofing?
Pooled water outside does not affect inside sealing. But draining water around the tank is also important. Waterproofing protects against seepage from inside the tank only.

Flat and shop both have damp: how do I know it is from the tank?
Inspection shows. If damp comes from above and below, it is from the tank. If it comes from the side, it may be from another leak.

How often must I inspect the tank after waterproofing in an old district?
First inspection one year after sealing. Old tanks may develop new cracks. Annual inspections afterwards help catch problems early.

Dense building with many flats and shops: does one tank serve all?
It may. A large shared tank may serve several flats and shops. Inspection shows which tanks and which users they serve.

After sealing, will the flat and shop return to normal?
New seepage stops at once. Old damp takes time to dry. Good ventilation and drying help the space recover fast.
