Foundation Drilling Fluids for Bored Piles, Barrettes and Diaphragm Walls
Engineered bentonite and polymer support-fluid systems selected from ground conditions, groundwater, excavation method, slurry behaviour and field QC requirements.
Start with the excavation
Support-fluid selection, formation behaviour, field QC, bottom cleaning and concrete readiness.
Open bored-pile decision guide → 02 / PANELS & BARRETTESDiaphragm Walls & BarrettesBentonite, polymer and engineered support-fluid systems for deep panels and rectangular foundation elements.
Open diaphragm-wall guide →Three starting routes
Select the support-fluid architecture first; use secondary additives only for a diagnosed missing function.
MINERAL SYSTEMALKABEN — BentoniteControlled rheology, filtration and mineral interface formation for suitable granular and mixed ground.
POWDER POLYMERPOLYWELLLow-mineral-solids polymer route for qualified foundation support-fluid systems.
LIQUID POLYMERDRILL-WELLRapid liquid-polymer preparation and controlled field adjustment.
Let the formation define the problem
Diagnose before adding chemical
Separate filtration from whole-fluid loss.
QCDensity increasingSeparate sand from fine silt/clay contamination.
BASEBottom sedimentClean the toe and final slurry separately.
FRICTIONCasing torque / extractionCheck mechanical causes before lubrication.
SOLIDSDirty slurry before concreteDesand, exchange or replace by contamination type.
TESTField QCRead density, Marsh, pH and sand together.
Calculate, check and record
Use project-approved inputs; the tools calculate and organize data but do not invent the required dosage or acceptance limits.
Add only the missing function
Filtration control with limited rheological contribution.
MUDOPAC HVFiltration control with additional rheology.
MUDOZANRheology and suspension where genuine carrying capacity is required.
MUDOCLAY-OFFDedicated reactive-clay inhibition and stabilization.
MUDOLUBEConditional friction/torque support after stability and solids causes are excluded.
