Home/FlowTex Dewatering Technology • Manufactured in South Africa
Manufacturing & QA/QC
South African fabrication of dewatering bags and tubes, with project-specific materials, seams, ports and inspection requirements.
Manufacturing & QA/QC
Selected for your slurry. Manufactured for your project.
Manufactured in South Africa for dewatering projects across Africa. FlowTex converts selected technical textiles into project-specific bags and tubes. Stock supply and custom fabrication are supported by an agreed specification for fabric, seams, dimensions, ports and inspection.
Product selection
Specifications that inform the right choice
Compare the published grades, then confirm the supplied construction and project requirements in the technical submission.
| FlowTex grade | Tensile MD/CD (kN/m) | O90 (µm) | Normal permeability (mm/s) | Mass (g/m²) |
|---|---|---|---|---|
| HF45 | 45 / 45 | 600 | 40 | 210 |
| HF60 | 60 / 60 | 600 | 27 | 280 |
| HF105 | 105 / 105 | 300 | 25 | 500 |
Technical notes and test basis
Nominal reference fabric values, subject to stated tolerances and the current project submission. Tensile: EN ISO 10319; O90: EN ISO 12956; normal permeability: EN ISO 11058; mass: EN ISO 9864. Fabric strength is not seam strength or allowable filling pressure.
| Dimension | How to specify it |
|---|---|
| Maximum stated fabrication size | Up to 15 m circumference × 30 m finished length |
| Lay-flat width at 15 m circumference | Approximately 7.5 m before seam allowances; not filled width |
| Circular-equivalent diameter at 15 m circumference | Approximately 4.77 m; a geometric reference, not operating height |
| Working capacity | Determined from filled geometry, allowable height, slurry density and consolidation |
| Ports and connections | Specify diameter, quantity, spacing, hose connection and filling sequence |
| Handling | State pad-based emptying or a separately designed and validated lifting duty |
Technical notes and test basis
Capability confirmed by FlowTex management. Availability of any size/fabric combination is subject to fabrication review. The maximum dimensions are not a guaranteed working volume, pump rating or approval to stack or lift.
From specification to site
Fabrication, QA/QC & African project supply
Material control
Specify polymer and construction, directional tensile properties, hydraulic properties and required durability evidence. Link fabric batches and thread identification to the manufacturing record; supplier sourcing details remain confidential.
Cutting and assembly
Control panel orientation, dimensions, seam allowances, stitch pattern, thread specification and port reinforcement using the approved fabrication drawing.
Seam qualification
Qualify the actual fabric/thread/stitch assembly and agree production sampling and acceptance criteria. ASTM D4884/D4884M addresses short-term geotextile seam strength; it is not a whole-bag lifting certificate.
Finished-container release
Agree visual inspection, dimensional checks, port and seam checks, identification, packing and release records. For lifting-duty products, include the separately defined lifting design and validation records.
A project QA dossier
Request the agreed material conformance documents, fabrication drawing, batch traceability, inspection records, applicable test reports, operating limits and installation/handling guidance. The exact dossier scope is stated in the proposal.
Release the correct product
Stock allocation must match the specified grade, dimensions and port configuration. For custom fabrication, confirm the drawing and inspection scope before production. Dispatch documentation should identify the supplied assembly and the applicable operating and handling instructions.
FAQ
Frequently asked questions
Are FlowTex dewatering bags and tubes available from stock?
FlowTex holds stock for immediate supply. Ask for the available grade, dimensions and quantity; allocation is confirmed for the order. Custom dimensions or a different construction require a fabrication programme. Dispatch readiness and delivery time are confirmed separately.
Is the fabric tensile value also the seam strength?
No. Seam strength depends on the actual fabric, thread, stitch and seam geometry. Request the applicable assembly test evidence and acceptance basis.
Which quality documents should be included in my order?
Agree the required fabric conformance evidence, fabrication drawing, batch identification, dimensional and visual checks, applicable seam or other test reports, and operating/handling instructions. The exact dossier is defined in the quoted scope.
