Construction, Foundation & Geotechnical Drilling

Start with the engineering function of the hole

Construction and geotechnical drilling can support site investigation, anchoring, grouting, foundation work, slope stabilization and underground construction. Diameter control, inclination, borehole stability, access and spoil removal may be as important as penetration.

Record site constraints

Restricted headroom, urban access, platform capacity, noise controls, water management and the need to work close to existing structures can affect rig size and drilling method. Send site photographs and working-envelope dimensions when space is limited.

Match the tool system

• PDC bits: discuss geometry, cleaning and connection for suitable ground and rock intervals.
• DTH systems: review hard-rock drilling with the compressor, hammer, bit and casing plan.
• Tricone bits: compare cutting structures for rotary drilling after formation and operating inputs are known.
• Rods and accessories: confirm thread, length and handling limits for the rig and site.
• Rigs: compare footprint, mast, feed, pullback, rotary head, mobility and support-equipment needs.

Send these project details

• Hole purpose, diameter, depth, inclination and tolerance
• Soil and rock sequence, groundwater and unstable intervals
• Site access, headroom and working-platform conditions
• Rig or proposed drilling method
• Flushing, casing and spoil-handling requirements
• Project schedule, quantity and delivery destination

Confirm engineering responsibility

Product selection does not replace the project design, site investigation or safe operating procedure. Use technical sales to confirm product compatibility after the project engineer has defined the drilling requirement.
