GEOBAG SYSTEMS / SUPPLY + DESIGN
GEOBAG SUPPLY + DESIGN · AUSTRALIA-WIDE
Geobag systems planned from slurry data to stacking layout and supply.
Kontain prepares the agreed civil specification, drawings, pad and drainage layout, bag sizing, stack planning and modelling, operating controls and material schedule—then supplies the geobags, liner and associated materials.

Project-specific technical documents
Geobag data and field procedures must match the material, filling system and containment controls. The correct document set is issued after the application review.
This page provides the public feasibility, selection and field-control basis. Kontain does not present one generic geobag TDS as suitable for every slurry or project.
COMMON PROJECT DRIVERS
Recover waterRemove pond sludgeManage dredged sedimentExpand tailings capacityReduce wet haulageTHE COMMERCIAL MODEL
Design and planning are included with the material supply.
Kontain does not add a separate design fee for the agreed geobag scope when appointed to supply the geobags, liner and associated materials. The technical work and supplied products are developed as one package so the specification, layout and order do not drift apart.
Review the transparent design-and-supply modelKontain does not guarantee dewatering rate, filtrate quality, final cake solids or programme. Outcomes remain dependent on representative testing, feed variability, chemical conditioning, pumping, weather, drainage and operator control.
The intent is to reduce avoidable design, product and operating risk and maximise the likelihood of a successful outcome using a clear technical basis and fit-for-purpose materials.01 · FEASIBILITY FIRST
Design the dewatering system before the bags are ordered.
The product is only one input. The commercial outcome is controlled by solids mass, filtration response, polymer demand, available area, water-management constraints, filling rate and the final cake-handling plan.
MINIMUM INPUT DATA
What we need for a useful first assessment
- 01Material definition
Slurry source, particle-size distribution, solids concentration, mineralogy, pH and contaminants.
- 02Hydraulic basis
Total wet volume, dredge or pump rate, operating hours and the water-return or discharge pathway.
- 03Site constraints
Usable footprint, levels, access, liner requirements and the final cake destination.
GO / DEVELOP / NO-GO SCREEN
Questions the proposal must answer
01
Can the solids be retained while producing a manageable filtrate?
02
Can the required dry tonnes fit within the available pad and programme?
03
Is a single layer sufficient, or is engineered stacking required?
04
What testing and regulatory evidence is needed before mobilisation?
05
Which dredging, pumping and polymer package can deliver the design basis?
02 · TECHNICAL DEVELOPMENT
Civil specification, drawings, layout and supply developed together.
Kontain works from concept and testing through to manufacture, delivery and filling support. We do not perform the dredging, pumping or day-to-day operation unless separately agreed; those delivery interfaces are defined so each party works to the same basis.
Mass balance & programme
Convert wet volume and solids concentration into dry tonnes, water release, container cycles, pump duty and operating duration.
Treatability & conditioning
Plan bench screening, candidate polymers, dose windows, make-down requirements, filtrate objectives and field verification.
Civil specification & drawings
Prepare the agreed plans, sections, material requirements, pad levels, drainage details and construction notes from the available project data.
Layout & stack planning
Optimise bag orientation, cells, access, headers, drainage, liner protection, lift geometry and filling sequence; model the stack where project conditions warrant it.
Bag configuration & manufacture
Set fabric, seam, port, dimensions and handling requirements around the slurry, geometry, load, programme and delivery constraints.
Operating basis & interfaces
Define fill controls, hold points and the interfaces between the operator, dredging, pumping, civil, polymer and material-supply scopes.
FOOTPRINT OPTIMISATION
Stack geometry is part of the civil layout—not an operator decision on the day.
Where horizontal area is limited, staged stacking can increase dry-solids capacity per square metre. It is not simply “bags on bags”: lower lifts must consolidate, drainage must remain open, foundation response and stability must be reviewed, and the filling sequence must be controlled.

Concept only. Final geometry requires project-specific assessment.03 · PRODUCT PLATFORM
Three technical starting points. Final selection follows the slurry.
Indicative attributes are shown for portfolio comparison. Project dimensions, port layout and the final fabric specification are confirmed after application review and, where warranted, treatability testing.
KGB 300HIGH-FLOW
Organic sludge, biosolids and difficult colloidal streams
- O95 0.425 mm
- Permeability ≈50 L/m²/s
- Seam strength >90 kN/m
KGB 500BALANCED RETENTION
Fine mine tailings and controlled industrial slurries
- O95 0.30 mm
- Permeability ≈40 L/m²/s
- Strength 90–130 kN/m
KGB 1000HIGH-STRENGTH
Stacked, high-load, coarse-sediment and long-term applications
- O95 ≈0.45 mm
- Tensile ≈200 kN/m MD/CD
- Seam strength >170 kN/m
O95, permeability and strength values are nominal portfolio descriptors—not a design specification or a guarantee of dewatering performance. Seam and fabric data must be reviewed with container geometry, fill height, stacking and operating controls.
04 · INSTALLATION & FILLING GUIDE
A designed system still depends on disciplined operation.
Pad preparation, alignment, flow, conditioning and permitted fill geometry materially affect results. The procedure sets measurable limits and nominates who can stop filling, but the operator remains responsible for following the agreed controls.
STAGEMINIMUM CONTROLHOLD / RESPONSE TRIGGER
01 · Pad releaseLevel survey, compaction, liner protection, drainage and sump ready.Soft spots, sharp objects, ponding or incomplete containment.
02 · DeploymentCentreline set-out, port orientation, spacing, seams and serial numbers checked.Twist, fold, misalignment, damaged fabric or blocked drainage path.
03 · PrimingLow initial flow, restrained hose, polymer response and filtrate observed.Poor floc, jetting, local hump, cloudy filtrate or unstable hose.
04 · Production fillApproved rate and height, perimeter inspections and balanced filling.Rapid local rise, rolling, seam distress, scour, leakage or height limit.
05 · Consolidation / stackingDrain-down period, geometry survey, lower-lift condition and access verified.Ongoing movement, trapped water, blocked drainage or foundation distress.
PRACTICAL FIELD SEQUENCE
Installation guidance included here
The project procedure should turn the design basis into a short, measurable field sequence used at pre-starts, hold points and shift handovers.
- 01Prepare and release the pad
Confirm formation, liner protection, fall, drainage paths, sump capacity, access and exclusion zones before any container is unloaded.
- 02Unload, identify and deploy
Lift from approved points, record container serial numbers, set centreline and port orientation, remove folds and inspect fabric and seams.
- 03Connect the filling system
Restrain the hose, use compatible fittings, establish isolation and diversion controls, and position personnel clear of pressurised lines.
- 04Prime at low flow
Confirm polymer response, filtrate clarity, even container rise and drainage performance before increasing toward the approved operating rate.
- 05Fill, inspect and record
Log flow, pressure or fill-height controls, polymer dose, filtrate observations and perimeter condition. Stop for movement, seam distress or abnormal leakage.
- 06Consolidate before the next cycle
Allow drain-down, survey geometry and confirm lower-lift stability and open drainage before refilling, stacking or commencing cake removal.

Start with the technical basis. Bring the dredging contractor in against a defined scope.
Kontain can connect asset owners with experienced dredging, pumping and dewatering companies from our project network. Our commercial interest in supplying the geobags and associated materials is stated clearly; each party can then price and plan against the same mass balance, layout, trial evidence and operating controls.
- Performance-based scope suitable for competitive contractor pricing
- Clear interfaces between civil, dredging, polymer, operation and material supply
- On-site support during set-up, trials and production filling where agreed
PRELIMINARY PROJECT REVIEW
Send the site and slurry data—not a finished specification.
A short discussion around the material, wet volume, site area, programme and water pathway is enough to identify the next useful step: desktop assessment, sample testing or a site visit.
