Drill Additives
HDD drill additives for horizontal directional drilling fluid systems. Choose products for clay control, cuttings suspension, hole cleaning, fluid loss support, and light-duty HDD ground conditions.
HDD Fluid Systems
Pick drill additives by soil condition
Choose the ground condition first. The recommended liquids will appear below and the product grid will narrow to the best match for that type of bore.
Filter by soil or drilling problem
Tap a condition to show only the additives that make sense for that job.
All drill additives
See the full fluid additive line, then select per unit or box on each product card.
- Use this view when the bore has mixed ground or you already know the product name.
- For uncertain jobs, call before ordering so mix rate and soil condition can be checked.
Sticky clay, gumbo, or reactive shale
Focus on reducing clay stickiness, swelling, and buildup on rods, tooling, and the bore path.
- Start with HydroForce for clay-control support.
- Use HydroDET when the tooling needs detergent / surfactant help.
- Add viscosity support if the hole also needs more carrying capacity.
Sand, gravel, cobble, or loose ground
Prioritize suspension, hole cleaning, and carrying cuttings out of the bore.
- LiftGuard helps support heavy or loose material.
- PolyGuardXP supports suspension and fluid control.
- RheoBore can help build a stable base mix.
Porous ground or fluid loss
Use products aimed at keeping drilling fluid in the bore and supporting unstable formations.
- PolyGuardXP is the primary pick for fluid loss support.
- RheonicHV helps when quick viscosity is needed.
- LiftGuard can help when the ground also needs suspension support.
Base mix, viscosity, and hole cleaning
Use this when the crew needs a general drilling fluid base for cuttings transport and bore stability.
- RheoBore is the base viscosity pick.
- RheonicHV is useful when fast viscosity build is needed.
- LiftGuard supports suspension when carrying capacity matters.
Recommendations depend on soil condition, water quality, bore length, tooling, and contractor requirements. Follow the product technical sheet and jobsite safety requirements.
