Drilling fluids
A fluid for every ground
Polymer drilling fluids and additives from ProAction Fluids, from sticky clay to sand, gravel and rock. Six products that work together — start from one base fluid and add what the ground calls for.
Synthetic polymer HDD fluid
TurboBore
A one-product drilling fluid: no recipe and no other additives needed. Best suited to sand and rocky soil.
View drilling fluids→
Soil stabiliser and viscosifier
ProDrill
Multi-polymer blend that builds viscosity and binds clay and other low-density solids, so the cuttings leave the bore cleanly. The base of the ProBore series.
View drilling fluids→
Water-based, hydrocarbon-free
ProDrill ECO
The water-based version of ProDrill, with no oil or hydrocarbons — for jobs where oil-based carrier fluids are not allowed.
View drilling fluids→
Drilling detergent and water conditioner
ProDyne
Non-foaming detergent that softens hard water and keeps sticky clay from clinging to the bit, the rods and the tooling.
View drilling fluids→
Clay control additive
ClayLock
Clay inhibitor that stops reactive clays from swelling and grabbing the pipe and the tooling.
View drilling fluids→
Liquid viscosifier, lubricant and filtration control
GeoSweep LQ
Liquid multi-polymer blend for dense, permeable ground from sand to rock: disperses quickly, carries coarse cuttings out and seals the bore wall.

Why HDD Gear
Built to outlast the rig it runs in
Certified steel
Every drill pipe and backreamer is built from certified alloy steel — armed with tungsten-carbide cutters where the ground turns hard. The ratings and dimensions you need are published for every part number.
Guaranteed fit
Drill-pipe tool joints and reamer connections are machined to the exact thread of every Ditch Witch, Vermeer and TT Technologies rig — IF and Reg, pin to box — so every tool is a true drop-in fit.
Fast delivery
We keep a broad inventory of drill pipe, tooling and drilling fluids, so standard orders ship fast — with express freight available when the job can't wait.
Tell us the job — we'll match the tools.
