Geomembrane Product Scope for International Projects
AQUA supplies geomembrane as a supporting procured product within its export supply process. It is not presented as output from AQUA’s injection-moulding lines, and controls used for moulded stormwater modules are not extended to geomembrane batches.
Material boundary
This page covers nonreinforced polyethylene sheet in the verified HDPE and LLDPE offer; where applicable, ASTM D5199 addresses nominal thickness rather than material or project approval. PVC, RPE, EPDM, bituminous liners and reinforced composite products are outside this product scope; a geotextile may protect or reinforce part of a designed system, but it is not the barrier sheet.
Primary material route
HDPE geomembrane liner
Start with HDPE when the project specification calls for a high-density polyethylene geomembrane. The review still needs chemical exposure, temperature, subgrade, slope, cover, seam and interface conditions before an order configuration is confirmed.
Working model example
ARW-GM-HDPE-1.0
The final code and description follow the ordered material, thickness, surface and dimensions.
Available alternative route
LLDPE geomembrane liner
Request LLDPE when the project calls for linear low-density polyethylene or when deformation and conformity are part of the engineering review. AQUA does not substitute LLDPE for HDPE without an agreed specification basis.
Working model example
ARW-GM-LLDPE-1.0
A model example is not a universal property sheet or approval.
Supply control without a false manufacturing claim
AQUA aligns the requested configuration, checks available order evidence, coordinates packing, reviews loading requirements and supports export documentation. Batch reports or certificates are provided only when applicable to the selected product and written into the order. Across both product routes, the order can state smooth, single-textured, or double-textured surfaces. Working model examples are ARW-GM-HDPE-1.0 and ARW-GM-LLDPE-1.0; each code remains bound to the quoted material and configuration.
HDPE-or-LLDPE and Smooth-or-Textured Selection Grid
Thickness or texture alone cannot select a lining system. Use the chart to make a shortlist and let the project engineer confirm chemistry, deformation, slope stability, subgrade, anchorage, cover and seam requirements.
HDPE and LLDPE are not interchangeable in an order. Texture is not a substitute for project-specific interface testing, and using the wrong material or surface can invalidate a comparison. Material and surface choices are project trade-offs, not an automatic ranking of smooth versus textured sheet performance.
Configuration
Reason to shortlist it
Inputs that can change the decision
Order checkpoint
Configuration
HDPE + smooth
Reason to shortlist it
Project documents already call for HDPE and the critical interface does not require a textured face.
Inputs that can change the decision
Chemical exposure, temperature, foundation condition, sheet stress, seam access and cover system.
Order checkpoint
Confirm material designation, thickness method, roll dimensions and required batch evidence.
Configuration
HDPE + textured
Reason to shortlist it
HDPE is specified and an interface may require a textured surface for project evaluation.
Inputs that can change the decision
Adjacent soil or geosynthetic, normal stress, slope, drainage, asperity requirement and direct-shear plan.
Order checkpoint
State single- or double-sided texture and the accepted textured-thickness method.
Configuration
LLDPE + smooth
Reason to shortlist it
LLDPE is specified or deformation/conformity is a stated design concern on a noncritical smooth interface.
Inputs that can change the decision
Strain demand, puncture environment, chemical exposure, temperature, cover and seam detail.
Order checkpoint
Confirm that LLDPE—not generic polyethylene—is named in the order.
Configuration
LLDPE + textured
Reason to shortlist it
LLDPE is specified and the system also needs a reviewed textured interface.
Inputs that can change the decision
Deformation, interface shear, adjacent layers, anchorage, drainage and construction sequence.
Order checkpoint
Keep material choice and surface choice as two separate approved fields.
More thickness is not automatically the better project answer, and a higher asperity does not automatically prove higher interface shear strength. For critical slopes or interfaces, use project-specific testing and qualified design review rather than a catalogue label.
Specification control note:
Freeze material, nominal thickness, surface, dimensions, colour and evidence scope together. If one field changes, reopen the comparison before approving the sample or bulk order.
Orderable Dimensions, Thicknesses, Colors, and Standards
Quote comparison can fail because a material label may hide a different thickness method or evidence scope. AQUA binds the quotation to the Six-Field Specification-to-Order Matrix below; its 0.3–3.0 mm range and the cited ASTM and GRI boundaries make each accepted field auditable before price, lead time or documentation is compared.
A written evidence basis follows the ordered GB/T 17643-2025 profile, GRI-GM13 for HDPE, GRI-GM17 for LLDPE, or another expressly specified test standard. Product capability and standard applicability remain separate decisions.
Six-Field Specification-to-Order Matrix
| Field | AQUA working range | What to write in the enquiry | Release rule |
|---|---|---|---|
| 1. Material | HDPE primary; LLDPE available | Name HDPE or LLDPE and the governing project specification. | No silent material substitution. |
| 2. Nominal thickness | 0.3–3.0 mm; common 0.5–3.0 mm increments | State the nominal thickness and applicable measurement method. | GRI-GM13 starts at 0.75 mm; GRI-GM17 starts at 0.50 mm. |
| 3. Surface | Smooth; optional single- or double-sided texture | Name each required face and any project interface criterion. | Texture does not replace interface-shear evaluation. |
| 4. Roll dimensions | 1–6 m width; custom roll length | Give width, length, quantity or area, handling limits and joining layout. | The quotation confirms the actual roll plan. |
| 5. Colour | Black standard; white from virgin resin; blue via colour masterbatch, subject to order review | State colour, exposure and any formulation or evidence requirement. | Black-product evidence is not automatically transferred to white or blue formulations. |
| 6. Evidence basis | Order-selected standard, checks and documents | List each required standard, test, report, certificate or inspection record. | Only accepted written items enter the supply scope. |
Ordered-Standard Applicability and Evidence Map
| Reference | What it can support | Applicability checkpoint | What it does not prove |
|---|---|---|---|
| GB/T 17643-2025 | Current Chinese national specification route for polyethylene geomembrane when ordered. | Confirm material, class, thickness, surface and requested evidence against the order. | It is not an automatic certificate for every AQUA roll. |
| GRI-GM13 Rev. 19 | Optional HDPE specification for 0.75–3.0 mm smooth and textured geomembranes. | Below 0.75 mm is outside its thickness scope; purchaser-requested certification must be order-bound. | It does not cover the full AQUA 0.3–3.0 mm offer. |
| GRI-GM17 Rev. 17 | Optional LLDPE specification for 0.50–3.0 mm smooth and textured geomembranes. | Below 0.50 mm is outside its thickness scope; confirm formulation and report scope. | It does not cover 0.3 mm LLDPE sheet. |
| ASTM D5199-25 | Nominal-thickness measurement for applicable geosynthetics. | Use only where the presser foot can fully contact the surface. | It is not the general thickness route for textured sheet and is not product certification. |
| ASTM D5994/D5994M | Core-thickness measurement route for textured geomembranes when specified. | Confirm the project method and reporting basis before release. | It does not prove interface shear strength. |
| ASTM D6392-25 | Destructive peel and shear integrity testing for applicable nonreinforced thermo-fusion seams. | Confirm material, seam process, specimens and acceptance basis. | It is not a nondestructive seam check or sheet-property specification. |
| ASTM D4437/D4437M-16(2023) | Nondestructive integrity checks for applicable flexible polymeric sheet seams. | Confirm the seam type, technique, frequency and record required. | It is not applicable to destructive testing. |
Project Conditions for Each Liner Configuration
Geomembrane sheets function as part of a containment system only after their supporting and overlying systems are in place. Across containment applications, environmental protection depends on the barrier system as a whole and on contact with the actual liquid or contaminant, rather than the roll description alone.
Choosing by application name or an ASTM D4437/D4437M seam-check result alone risks placing the wrong 0.3–3.0 mm configuration into the project; use the condition cards to identify the inputs that still need review.
Identify stored-water chemistry, water level, exposed area, ultraviolet exposure, bank slope, anchorage, inlet/outlet penetrations and whether soil or another layer covers the liner.
State water quality, cleaning method, contact requirements, subgrade condition, expected movement, access for repair, exposed edges and the intended protective layer.
Provide the liquid composition, concentration, temperature, exposure duration, cleaning chemicals, foundation, penetrations and required regulatory or project specification.
For a heap-leach area, tailing pond or covered slope, define geometry, normal stress, ore or cover interface, drainage, anchorage, subgrade, construction traffic, seam access and the laboratory interface-test plan.
Separate basal, cap, secondary and temporary-cover duties. Each can carry different settlement, gas, drainage, interface, seam and quality-assurance requirements.
Submit the drawing and layer build-up rather than an application name alone. A channel, reservoir, lagoon, tank area or secondary-containment pad can impose different restraints and penetrations.
Specification control note:
These application notes order the enquiry; they are not project designs, installation instructions or guarantees of suitability.
Quote Inputs, Samples, Minimum Order, and Production Planning
A price per square metre is only comparable when specification and delivery bases are comparable. Where any field is different, quotes are not comparable. The result of this mismatch can easily cause a shift in roll use, evidence, packing or delivery. The Six-Input Quote Readiness Checklist allows these differences to be identified before a commercial negotiation.
The Six-Input Quote Readiness Checklist
1
Application and service conditions:
describe the contained liquid or material, chemistry, temperature, exposure duration, slope and cover condition.
2
Product configuration:
state HDPE or LLDPE, nominal thickness, smooth or textured faces, colour, width and roll length.
3
Quantity and layout:
include total area, roll plan when applicable, seam allowance, project drawings and any phased deliveries. Confirm the required roll plan and phased quantities. Add the latest acceptable shipment window.
4
Evidence package:
List the ordered standard, inspection, test, report, certificate, traceability, and witness requirements.
5
Packing and destination:
include the destination country, receiving constraints, container preference, handling equipment and requested trade term. Confirm the packing and loading requirements. These details help the products reach the destination in the specified condition.
6
Timing:
state the required delivery date, approval steps and latest acceptable sample window.
Commercial Execution Policies
The working MOQ is one small container. Mixed-product consolidation or another shipment approach can be reviewed, but the quotation confirms feasibility.
One sample can be supplied free of product charge after sample dimensions and freight responsibility are confirmed. Use the same material, thickness, surface and colour fields intended for the quote.
Approximately 7 days is a working reference after specification, commercial terms and material are confirmed. Order mix, formulation, dimensions, quantity and scheduling can change the written lead time.
A cost-effective comparison covers sheet configuration, roll utilization, packing, freight, site handling, subgrade work, seaming, quality assurance, leak investigation and repair access. Cost-effectiveness cannot be reduced to a context-free saving percentage, payback period or service-life figure, so AQUA publishes none of those numbers.
Product Inspection Checks and Order Documentation
The control plan must list the complete characteristics, methods, frequencies, acceptance basis and record for the supplied batch. One certificate cannot act as material identity, dimensions, seam checks, and project acceptance.
| Control point | What AQUA coordinates | What the order must define |
|---|---|---|
| Configuration review | Material, nominal thickness, surface, colour, roll dimensions, quantity and destination are checked against the quotation. | Approved drawing, specification revision and substitution rule. |
| Batch evidence | Available certificate of analysis, manufacturer test report or checklist can be coordinated when applicable. | Required values, method, frequency, lot traceability and acceptance criteria. |
| Thickness evidence | The requested method is matched to the smooth or textured surface. | D5199 for applicable surfaces or a confirmed textured-sheet method such as D5994/D5994M. |
| Seam evidence | Documents can be included when a weld seam scope is part of supply or project support. | Destructive or nondestructive route, technique, frequency, installer responsibility and acceptance basis. |
| Packing and loading | Roll identification, packing configuration and loading requirements are reviewed before shipment. | Labels, roll list, handling restrictions, container securing and photographic record if required. |
STATEMENT

Supply Scope Statement
Supply support can be mistaken for complete construction responsibility. AQUA can supply material and installation accessories when a project genuinely requires them, but remains a product and supporting-material supplier. AQUA will not be the contracted installer of a project.
Application Gallery for Geomembrane Lining Projects
The following photographs show contextual lining examples. They do not identify a customer, location, supplied batch, installation contractor or verified AQUA project outcome.
Water-storage context
confirm bank slope, anchorage, water chemistry, exposure and inlet or outlet details.
Agriculture or aquaculture context
define water contact, cleaning, subgrade, edges and maintenance access.
Industrial or wastewater context
provide chemistry, temperature, penetrations, seams and containment duty.
Large-slope context
treat interface shear, drainage, anchorage, cover stability and construction sequence as design inputs.
Project Conditions That Need Additional Engineering Review
Pause product release until project conditions are specific enough to confirm material, surface or thickness. An undefined interface can create a significant containment and logistical issue and is best addressed through a defined review. Unresolved inputs can create significant logistical problems.
Provide the chemical name, concentration, temperature, exposure pattern and cleaning regime. A generic “industrial wastewater” label cannot establish compatibility or service life, so request a specific input review before order release.
Ask the project engineer whether subliner drainage, venting, monitoring or uplift resistance is needed. Sheet thickness alone does not resolve pressure below the geomembrane.
Define every interface, adjacent material, normal stress, moisture, cover geometry and drainage condition. Project-specific direct shear testing may be required.
Identify angular particles, irregular surfaces, settlement, voids, cushion layers, penetrations and construction traffic. The layer build-up and deformation demand can change the material or protection plan.
White and blue options require formulation and evidence confirmation. Do not assume a black GRI formulation, including its carbon-black requirements, applies unchanged to another colour.
Submit the exact contractual requirement and exposure conditions. AQUA does not publish one fixed warranty or design life for all geomembrane products and projects.

FAQ: Geomembrane Product Questions
What is the difference between a geomembrane and a geotextile?
A geomembrane is selected as a low-permeability barrier, while a geotextile is generally permeable and used for functions such as separation, filtration, drainage or protection. “Impermeable” should not be read as a universal zero-leak guarantee; a lining system may use both products, but they do not replace each other automatically.
What information is needed when gas or groundwater pressure may build below the liner?
Provide the subgrade profile, groundwater level, expected gas source, cover load, slope, drainage concept and monitoring requirements. The project engineer should determine whether venting, drainage, uplift resistance or another system measure is required.
Does a thicker geomembrane always give better project performance?
No. Use the project specification and engineering review; thickness alone cannot establish suitability.
When should I request smooth or textured geomembrane?
Smooth sheet can be shortlisted where the critical interface does not require texture. For a slope or covered system, state each adjacent material and let the design and test plan determine whether single- or double-sided texture is appropriate.
Can AQUA quote 0.3 mm geomembrane to GRI-GM13 or GRI-GM17?
The 0.3 mm option is within AQUA’s owner-confirmed orderable range, but it is below the verified thickness scope of both GRI-GM13 and GRI-GM17. The quotation must use another agreed specification and evidence basis for that thickness.
Can I get a sample before placing an order?
Yes. One sample can be supplied free of product charge after dimensions and freight responsibility are confirmed; state the material, thickness, surface and colour you want evaluated.
What is the minimum order and production-planning time?
The working MOQ is one small container, and approximately 7 days is the current planning reference after specification, commercial terms and material are confirmed. Your quotation sets the final order quantity, production timing and shipment basis.
Does AQUA install the complete geomembrane system?
No. AQUA supplies products, supporting materials and product-related documentation; remote guidance, accessories and one or two technicians may be arranged when genuinely needed, but the project contractor remains responsible for all field construction and installation work.
