Overhead tank waterproofing in Al Ahsa: An elevated concrete tank on columns with a damp patch at its base

Overhead tank waterproofing in Al Ahsa

In Al Ahsa, overhead tanks on roofs face heat and water all year, and damp patches often appear around their base or on the ceiling below. Al Raya treats the concrete tank walls and base inside and out to stop leaks and dampness.

What the service includes

What overhead tank waterproofing includes

  • Inspecting the inner concrete walls of the tank and identifying cracks and weak joints
  • Inspecting the tank base and the concrete stand and tracing the water's path to the roof or ceiling
  • Treating cracks and preparing the surface before any waterproofing coat is applied
  • Waterproofing the inner walls with a material suited to concrete in contact with water
  • Waterproofing the outer walls and the base to stop damp reaching the roof slab and ceiling
  • Treating the tank stand where it is a path for damp to travel downward
How we work

From your call to the treated tank

  1. 1

    Describe what you see

    Call or message us on WhatsApp and tell us where the damp appears: on the ceiling below the tank, around the base on the roof, or on the outer walls of the tank.

  2. 2

    Checking the tank and the base

    We inspect the inner and outer walls of the tank, the base and the stand, to trace the water and find where cracks form or a joint has weakened.

  3. 3

    Preparing the surface and treating it

    Preparing the surface is a core part of the job: the walls are cleaned and cracks are treated before the waterproofing coat goes on, because a coat on an unprepared surface will not hold.

  4. 4

    Waterproofing inside and out

    The walls are waterproofed inside to stop water passing through the concrete, and the base and outer walls are waterproofed to protect the roof and the ceiling below from accumulated damp.

About the area

The service in Al Ahsa

Overhead tanks are common on homes in a city like Al Ahsa, standing on flat roofs exposed to sun and rain. Water enters through cracks in the tank walls or around the base, especially if the concrete is old or weak. Work starts by checking the tank, the area around it, and the ceiling below to trace the leak path. Then surfaces are prepared and treated with waterproofing materials such as epoxy and bitumen to ensure dampness does not return.

Al Ahsa is a city in Al-Ahsa governorate in the Eastern Province, close to As Saifa District, Ayn Najm District and Al Muhammadiyah District.

A leak from the overhead tank is first noticed as a damp patch on the ceiling of the room directly below it.

Questions

Questions about Overhead tank waterproofing in Al Ahsa

In most cases no, because damp that builds up on the outer wall of the tank or under its base reaches the roof and the ceiling below without passing through the inside. So the work usually covers the outer walls and the base as well as the inner treatment.

Water travels horizontally under the concrete before it appears on the ceiling surface, so the stain's position does not have to match the source. The source is often the tank base or an expansion joint, and the mark shows elsewhere. That is why the work starts by tracing the source.

The tank stand receives water leaking from the base and the lower walls, and over time cracks form in it and the concrete deteriorates from repeated damp. Treating the stand is part of treating the overhead tank when it is the water's path to the roof.

An expansion joint is a deliberate gap left in the concrete to absorb movement with heat and cold changes; it is relatively wide with regular edges. A shrinkage crack forms from unexpected settlement or contraction and has an irregular shape. Both are possible leak paths and need treatment before waterproofing.

Tell us exactly where the damp shows: on the ceiling below the tank, around its base on the roof, or on its outer walls. Tell us whether it is a concrete tank and whether the damp appears constantly or only after the tank is filled. These details help us gauge the scope of the work.

The damp patch is usually directly below the tank's position on the roof, and it gets worse after the tank is filled with water. Inspecting the tank, base and pipes identifies the exact source.

Treatment usually requires both inside and outside work, especially if cracks are deep or the base is weak. The initial inspection decides whether one-sided treatment is enough.
