Site and depth planning
Position and depth chosen to suit the transfer pump and surface loads
Water tank installation
Built solid, sealed and ready to serve
Concrete block or cast walls, a tested waterproof coat and correct pipe entries, not a tank that weeps from day one due to poor construction
- 24-hour emergency
- Camera first, every job
- Leak detection without breaking
- All six governorates
What the job covers
From ground-level planning and excavation through to final connection and testing
Walls and base construction
Base and walls built to carry soil pressure and full water load
Full waterproof lining
Internal and external coating layers that block water movement in both directions
Pipe entry points
Inlet and outlet openings sealed with rubber collars to prevent pipe-joint leaks
Pump and float connection
Transfer pump and water-level float wired and adjusted for correct operation
Tightness test
Tank filled and water level watched to confirm zero leakage before backfilling
How the job runs
Call or WhatsApp
Describe the site and required capacity to arrange an assessment visit
Site assessment
Soil checked, dimensions set, depth and pipe route confirmed on site
Excavation and build
Pit dug, base poured, walls built and pipe penetrations prepared
Coating and connection
Waterproof coats applied inside and out, then pipes and pump connected
Test and handover
Tank filled, water level monitored, backfilled and handed over after passing test
Materials and methods used
Reinforced concrete or dense block
Carries sustained soil and water pressure without cracking over time
Crystalline waterproof coating
Penetrates concrete pores and self-seals hairline cracks when water contacts it
Rubber pipe collars
Seals each pipe at the tank wall and stops leaks at every penetration point
PPR pipework for internal runs
Unaffected by Kuwait's hard alkaline water and will not corrode inside the tank
Common mistakes in tank construction
Backfilling before testing
Buries leaks underground and the fault only shows after significant water loss
Skipping the external coat
Groundwater seeps inward and contaminates the stored water supply
Unsealed pipe opening
Every opening without a rubber collar becomes a guaranteed leak path over time
Insufficient cover depth
A thin slab cracks under vehicle movement or loads placed above the tank

What decides the price
No fixed rate applies; these are the factors that shape the final quote
Tank capacity
Larger volume means more materials, wider excavation and higher cost
Soil type and depth
Hard or wet soil increases excavation time and may need extra shoring
Wall thickness and reinforcement
Heavy loads above require thicker reinforcement and greater concrete volume
Pipe run length
Distance between tank and building directly affects pipe quantity and trenching
Cover slab type
A vehicle-rated lid differs in reinforcement and depth from a pedestrian cover

Common questions
Questions about underground tank construction

+965 9668 4964
Can an underground tank be built in a home garden without harming the foundations?
Yes, provided the tank is positioned far enough from the foundation line. The site assessment confirms the safe clearance before any excavation begins.
Why does an underground tank sometimes get contaminated by groundwater?
The cause is almost always a missing external waterproof coat or an unsealed pipe entry. Groundwater finds any unprotected gap and seeps inward.
Is an underground tank suitable for a residential building with more than 10 apartments?
Yes, and many Kuwaiti buildings use it as the primary collection tank from which water is pumped to upper floors. Capacity and structural design scale to the building size.
How can I tell whether an existing underground tank is leaking and not the pump causing the issue?
Stop the pump and close all inlet valves, then watch the water level for several hours. If the level drops with pumping halted, the tank is leaking, not the pump.
Can an old underground tank be rehabilitated with waterproofing instead of demolishing and rebuilding it?
It depends on wall condition. If walls are sound with no structural cracking, the tank can be cleaned and recoated. If the structure itself is cracked, rebuilding is the more practical choice.
