Pillar B Borewell & groundwater infrastructure
Borewell &
groundwater.
Tube wells drilled through overburden and rock, cased, gravel-packed, developed and yield-tested — Ø 5″ to 12″ bores, delivered to department and EPC specifications.

What happens
underground.
Surface Depth
Through the soil
ODEX drilling advances casing through pebbles, boulders and collapsible formations that stop a conventional bore.
- ODEX method
- Unconsolidated ground
- Ø 5″ – 12″
Piles that carry load
Bored and micro-piling for buildings, plants and structures — 200 mm to 2000 mm diameter, reinforcement cages made to suit.
- Micro / DTH / ODEX
- Auger · DMC · Rotary
- Cage making
Casing & lowering
MS ERW casing and slotted strainer pipe lowered to depth, welded, plumbed and capped to specification.
- MS casing
- Slotted screen
- Steel fabrication
Into hard rock
DTH hammer and rotary drilling take the bore through rock — the depth where most contractors stop.
- DTH hammer
- DC / RC rotary
- Deep bores
Water, proven
Gravel packing, compressor development and yield testing until the bore delivers clear, sand-free water — then pump and electrical installation.
- Gravel pack
- Compressor development
- Yield test
Counter runs to 275 m — the drilling depth in one of our supplied work orders (Kanpur Dehat, U.P.). Schematic, not to scale.
Borewell / tube well Execution process
Seven steps.
One measured result.
Rig, casing and crew mobilised to the marked point. Access, water and safety barriers set up before drilling starts.
Plant & equipment Rigs by method
Machines that
