How the job runs
Call or WhatsApp
Describe the tank type, size and when it was last cleaned
Camera inspection
Internal camera records sediment, cracks and wall condition before work
Drain and clean
Pressure wash and full vacuum until surfaces are completely dry
Seal or repair
Epoxy lining, fibreglass laminate or welding applied as the condition requires
Final check and handover
Second camera shown beside the opening footage so you see the result
Materials and methods used
Drinking-water epoxy coating
Epoxy rated for potable water contact, sealing pores and protecting concrete from scale and rust
Fibreglass laminate resin
Glass-fibre mat layers saturated with resin, restoring rigidity to a cracked or degraded tank wall
Internal inspection camera
Films the tank floor and walls before and after work so the customer sees the result directly on screen
High-pressure flush and vacuum
Pressure wash lifts compacted sediment and algae; full vacuum extraction before any coating is applied
Common mistakes in tank cleaning and waterproofing
Coating a wet surface
Applying sealant before the tank is fully dry prevents adhesion and causes the coat to peel within months
Skipping surface preparation
Painting over mineral scale or rust traps the contaminant inside the wall instead of removing it
Using non-rated materials
General construction sealants release compounds into drinking water and are not rated for potable contact
No post-work inspection
Without a camera check after completion, hairline cracks stay hidden and the problem returns by the next hot season
How tank cleaning and waterproofing is done correctly
Work begins with an internal camera recording before the tank is emptied, identifying sediment zones, cracks and the mineral scale that Kuwait's hard water builds on concrete and fibreglass surfaces. After full drainage the walls are pressure-washed and vacuumed, then allowed to dry completely. This preparation stage is not a formality: any coating applied to a damp or scaled surface will fail regardless of its quality.
The choice of waterproofing material depends on the tank type and its condition. Cracked concrete tanks receive a two-coat drinking-water epoxy lining. Degraded fibreglass tanks need resin-and-mat laminate repair before any surface coat. Steel or polyethylene tanks with structural fractures are welded first. Full replacement is a last resort used only when the tank structure itself is no longer sound, not as a default recommendation for any visible crack or stain.
Work closes with a second camera inspection shown on screen alongside the opening footage, giving the owner a direct visual comparison. Roof tanks in Kuwait face extreme summer heat that accelerates coating breakdown and opens hairline cracks faster than in cooler climates, making periodic inspection a practical necessity rather than an overcaution. Transfer and pressure pumps connected to the tank fall outside this service and are handled separately under pump installation and servicing.

What decides the price
No fixed rate applies; these factors shape every quote for this service
Tank size and type
A large underground tank needs more cleaning and coating time than a small roof unit
Type of work required
Cleaning alone differs in scope from cleaning combined with full epoxy lining or structural repair
Wall and floor condition
Heavy scale or multiple cracks increase preparation time and the volume of material needed
Access difficulty
Tanks with a narrow hatch or awkward location need extra effort to enter and work inside
Visit timing
Emergency call-outs outside normal hours are priced differently from pre-scheduled visits

How do I know the tank needs cleaning before taste or colour changes appear in the water?
A faint odour when you first open a tap in the morning or a light sediment at the bottom of a glass are early signs. An internal camera check reveals buildup and algae before they reach a level that affects the water at the tap.
Can an underground tank be waterproofed without breaking the surrounding floor?
Yes. The lining is applied from inside through the existing access hatch. External breaking is a last resort used only when the tank structure has a fracture that cannot be addressed from the inside.
What is the difference between cleaning a tank and waterproofing it, and do they always need to be done together?
Cleaning removes sediment and algae but does not close cracks. Waterproofing closes cracks and protects the walls but fails if applied to an unprepared surface. Both are needed when cracks are present; a structurally sound tank due for routine maintenance may need cleaning alone.
My fibreglass tank has hairline cracks; is repair possible or does it need to be replaced?
Hairline cracks in fibreglass are treated with resin-and-mat laminate from the inside, followed by an epoxy coat. Replacement is recommended only when the structure has deteriorated across too large an area to hold a repair patch.
Is the epoxy coating used genuinely safe for drinking water or is it a general-purpose surface paint?
The material used in drinking-water tanks must be rated for potable water contact, not a general construction paint. The distinction matters because a non-rated coating leaches compounds into stored water, which is exactly what the lining is meant to prevent.
Do you clean tanks in residential complexes and commercial buildings or only in homes?
The service covers homes, apartments, residential complexes, offices, restaurants and commercial kitchens. Larger buildings with multiple tanks can be scheduled for an extended visit to cover all units in one organised call-out.
