What fibreglass tank lining includes
- Inspecting the inner wall and base after the tank is emptied
- Locating the cracks and assessing how far the surface layer is damaged
- Treating the cracks with a flexible resin material that tolerates fibreglass wall movement
- Preparing and cleaning the inner surface before the new lining is applied
- Applying the inner lining to the full walls and base of the tank
- Checking that joints, edges and any weak point on the surface are fully covered
From your call to a re-lined tank

Tell us what you notice
Call or message us on WhatsApp and describe the tank, whether the water level drops, whether you see discolouration or damp below it.

Inspecting the inner wall
We empty the tank and inspect the inner wall and base, locating the cracks and assessing how far the surface layer is damaged.
- 3
Treating the cracks and preparing the surface
The cracks are treated with a flexible resin material that tolerates movement in the fibreglass wall, then the surface is cleaned and prepared before lining.
- 4
Re-lining the inside
The new lining is applied to the full inner surface once it is ready, covering the walls and the base of the tank.
The tank is repaired, not replaced
- We treat cracks with a material that matches fibreglass flexibility
- We inspect the inner wall and base before any lining
- We re-line the full surface, not the crack alone
- We take your request by phone call or WhatsApp message

The service in Ash Shi’bah
Fibreglass tanks are common in homes and buildings in a district like Ash Shi'bah, and their walls move slightly with pressure and heat, so small cracks and joints may widen over time. Leaks often appear at the tank base or where pipes join it, and you may notice damp under the tank or slow water seepage. The first inspection pinpoints the leak, then the tank's inner surface is prepared and cracks are treated with material suited to fibreglass. The material bonds firmly to the flexible wall without stopping its movement.
Ash Shi'bah is a district in Al-Ahsa governorate in the Eastern Province, close to Al Qurayn, Julayjilah and Ash Shuqayq.
An internal inspection of the tank reveals a crack even if it is fine, because the leak source is seen directly from inside.

Questions about Fibreglass tank lining in Ash Shi’bah
The clearest signs are a falling water level without use, or damp and a stain below or around the tank. Sometimes the water changes colour or a thin cracked layer peels from the inner wall. Any of these signs calls for an inspection before the damage spreads.
Because a fibreglass wall moves slightly under the weight of water and changes in temperature. If the lining is applied over an open crack, the new layer will crack at that point. The crack is treated with a flexible material that absorbs movement before the full surface is covered.
In many cases yes. A full inner lining covers wide surface damage after the cracks are treated and the wall prepared. This depends on the extent of the damage and the condition of the wall itself, which is why the work always starts with inspecting the inner surface to see what the tank actually needs.
Yes. Concrete is rigid and thick-walled, and its cracks are usually treated with cement-based or rigid resin materials. Fibreglass is thin and flexible, so a rigid filler will separate from the surface at the first movement. Fibreglass cracks need a flexible resin material that suits the nature of the wall.
Tell us the size and position of the tank, whether it is overhead or at ground level, and describe what you see: whether the water level drops, whether there is damp below, whether you can see a crack or peeling on the inner wall. The clearer your description, the better we can judge what the tank needs before we arrive.
If you see damp below the tank, slow dripping water, or the water level dropping without clear reason, the tank may be leaking. Call Al Raya to inspect the tank inside and out.
We inspect the tank to locate the leak precisely, then prepare the inner surface by cleaning it thoroughly and assess the type of crack or joint. A thorough first inspection determines which material suits the fibreglass wall.
