Sixteen products.
One quality system.

HDPE geomembrane, geotextile, GCL, drainage and waterproofing for mining, landfill, road and water projects — with the test reports your engineer asks for.

Product range

Six families, one mill. Custom width and roll length on every line.

Geomembranes

HDPE liner for containment

  • Smooth HDPE — 0.2–3.0 mm, width 1–8 m, roll 50–100 m
  • Textured HDPE — 1.0–3.0 mm, roughness height ≥0.25 mm
  • Column-point HDPE — 0.8–3.0 mm, width 1–8 m
  • Aquaculture liner — 0.2–3.0 mm, width 1–8 m

Used for: Landfill, tailings, ponds, reservoirs, wastewater

Geotextiles

Separation, filtration, drainage, reinforcement

  • Short-staple nonwoven — 100–1,000 g/m², width 1–8 m; nominal strength 3–40 kN/m
  • Continuous filament — 100–800 g/m², width 1–6 m; tensile 6–54 kN/m
  • PP needle-punched — SNGPP100–SNGPP1200, width 1–8 m
  • Hot-rolled nonwoven — 100–1,000 g/m², width 1–6 m
  • Woven PP — 90–400 g/m², width 1–6 m; MD 20–100 kN/m

Used for: Road, rail, drainage, embankment, slope works

Clay liners

GCL — sodium bentonite barrier

  • 3000–6000 g/m², width 3–6 m, roll 30–50 m
  • Bentonite mass ≥4000 g/m²
  • Swell index ≥24 mL/2g
  • Permeability ≤5.0×10⁻¹¹ / ≤5.0×10⁻¹² m/s, by type

Used for: Landfill, canal, lagoon, mining containment

Composites

Two functions in one roll

  • Composite geomembrane — 200–1000 g/m², width 1–6 m; membrane 0.30–1.00 mm, peel ≥6 N/cm
  • Composite drainage geonet — 4–8 mm, width 3 m, roll 30–50 m; in-plane flow ≥3.0×10⁻⁴ m²/s

Used for: Canal, tunnel, landfill drainage

Waterproofing

Tunnel and underground

  • EVA tunnel waterproof plate — 1.0–1.5 mm, width 2–6 m; tensile ≥16 MPa at 23 °C, ≥6 MPa at 60 °C
  • Plastic drainage plate — protrusion 8–50 mm, width 2–3 m; tensile ≥350 N/100 mm

Used for: Tunnel, basement, retaining wall

Erosion control

Slope and channel protection

  • Cement blanket — 6 / 8 / 10 / 12 / 15 kg/m², specification to be agreed per project
  • Slope protection eco-bag — 800×400×400 mm, 600×400×400 mm, custom sizes available

Used for: Channel, embankment, restoration

On specifications: the figures on this page are the range produced for each product family. The binding values for your order — thickness, mass per unit area, tensile, tear, puncture, OIT — are stated in the technical data sheet (TDS) issued against that order. Ask for it before you design, and we will send the exact grades available.

The standard your engineer will ask about

Our landfill liner is made to CJ/T 234-2006, which is equivalent to US GRI-GM13 — so the specification maps onto the ASTM language already in your design.

Property (HDPE, 1.5 mm)ValueWhy it matters
Tensile yield≥22 N/mmResists installation damage
Tensile break≥40 N/mmSurvives differential settlement
Elongation at break≥700%Stretches over uneven subgrade
Tear resistance≥190 NTears do not run
Puncture resistance≥480 NStones and rubble do not perforate
Carbon black2.0–3.0%UV protection in exposed service
OIT≥100 minOxidation life in the ground
What we will not do: claim full GM13 compliance without a test. Third-party ASTM / SGS testing can be arranged on the batch — tell us the specification and we quote it separately.

Where it goes

Mining and tailings

Textured and column-point HDPE, GCL and drainage geonet. Heat, UV and steep slopes.

Landfill

Smooth HDPE 1.5 mm, GCL and drainage geonet. Leachate containment and gas venting.

Road and rail

Filament, PP needle-punched and hot-rolled geotextile. Separation, filtration, subgrade reinforcement.

Water storage

Smooth HDPE 1.0–2.0 mm for reservoirs and process ponds in evaporative climates.

Aquaculture

HDPE liner 0.75–1.5 mm. Water saving and a clean pond bottom.

Tunnel and underground

EVA waterproof plate and drainage plate. Waterproofing plus drainage behind the lining.

What ships with the roll

TDS

Technical data sheet for the exact grade and thickness supplied.

COA

Batch certificate: density, tensile, tear, puncture, carbon black, OIT.

Roll list

Every roll with batch number, matched to the packing list.

Loading plan

Container count calculated before freight is quoted.

Application, area, destination port.

Three things is enough for a specification recommendation and a price — usually within 48 hours.
