Crack welding
direct thermal weld along each fracture line in the tank wall
What the service covers
welding cracks, failed joints and damaged fittings in plastic and fibreglass water tanks
Joint repair
re-welding inlet and outlet fittings where the flange joint has failed
Fibreglass patching
resin-and-mat layer over the damaged zone before the final weld seal
Seal verification
internal camera after welding reveals any weak point before refilling
Hatch replacement
replacing the tank lid when the leak source is the cover seal
Post-work report
written record of weld locations and camera inspection result
How the job runs
Call or WhatsApp
describe the leak location and tank type; a visit is scheduled
Camera inspection
internal camera maps every crack point before any welding starts
Surface preparation
weld zone cleaned, dried and cleared of any adhering deposits
Welding and patching
thermal weld or resin-and-mat applied according to material and damage severity
Post-work check
second camera pass confirms the seal and a report is handed to the customer
Signs your tank needs welding
Persistent damp patch
dampness that does not dry under the tank despite no visible pipe running there
Paint lifting beneath the tank
cracking or bubbling paint on the surface directly under the tank signals a slow cumulative drip
Unexplained level drop
the tank level drops beyond normal consumption even when no tap or fixture is running
Visible wall crack
a visible fracture or gap in the plastic or fibreglass tank wall spotted during an internal check
Materials and methods used
Thermoplastic welding
controlled heat fuses both crack edges without filler, suited to polyethylene tanks
Compatible welding rod
rod matching the tank material fills deep gaps and ensures matched thermal expansion
Epoxy filler for surface prep
applied to fibreglass before welding to level the damaged surface and improve layer adhesion
Fibreglass woven mat
resin-soaked mat wrapped around the repair zone distributes stress and stops the crack extending

What decides the price
no fixed price list applies; the quote is shaped by these factors
Number of weld points
each crack or failed joint is counted separately when estimating the work
Tank material type
polyethylene and fibreglass differ in welding tools and time required
Location and access
roof or ground position affects setup time and the lighting equipment needed
Tank capacity
larger tanks take longer to drain and inspect before work begins
Pre-weld cleaning need
scale or algae deposits must be removed before welding, adding time to the visit

+965 9668 4964
Can a plastic tank be welded without replacing the whole unit?
Yes. If the wall is sound overall and the crack is localised, a thermal weld restores the seal permanently. Full replacement is only recommended when damage is spread across a large section of the wall.
Does Kuwait's hard water affect how long a welded repair lasts?
Hard water deposits scale on the tank wall rather than on the weld itself, so the repair is not weakened. Periodic cleaning is still recommended to stop scale hiding any new cracks that may develop.
How do you locate the exact crack position before welding?
The tank is drained and an internal camera films every wall and the floor. Cracks and corroded joints appear clearly on the screen; the customer sees the same view before any work begins.
Is tank welding safe for drinking-water tanks?
Thermal welding uses a rod of the same base material as the tank with no foreign additives, making it suitable for drinking-water tanks. The tank is flushed before being returned to service.
Can a roof tank be welded in place without dismantling it?
In most cases yes. As long as the access opening allows tools through, welding is done from inside or outside depending on where the crack sits. Dismantling is only used when the position prevents adequate access.
