Geocomposite Materials Supplier:Integrated Solutions for Drainage, Reinforcement, and Sealing
Discover how geotextile, geonet, geomembrane, and geogrid can be combined into high-performance composite systems.
Composite Geomembrane (Geomembrane + Geotextile)
Landfill bases & caps, tailings/industrial ponds, reservoirs and canals, tunnel/basement waterproofing, roof garden drainage/waterproofing, dams and levees, highways/airports where reinforced anti-seepage is required.
A laminated geosynthetic that bonds a waterproof geomembrane (HDPE/LLDPE/PVC/EVA) with one or two layers of geotextile. The membrane delivers impermeability, while the geotextile provides mechanical protection, filtration, and separation—giving a single sheet that installs fast and performs in harsh conditions.
Key Features & Explanations
Reliable anti-seepage
The polymer film (typically HDPE or LLDPE) forms a continuous barrier against water and chemicals, making it suitable for reservoirs, canals, tailing ponds, and landfill liners.High puncture & tear resistance
The geotextile layer(s) cushion the membrane during placement/backfill and distribute point loads. This reduces installation damage and extends service life, especially on angular subgrades.Stable bonding under load
Thermal or adhesive lamination keeps layers integrated, preventing slip between fabric and film during settlement, traffic, or hydraulic uplift.Chemical & UV durability
Polymer selection plus anti-oxidant/UV stabilizers enable long-term exposure and resistance to acids, alkalis, and leachates—critical in waste and industrial water projects.Efficient construction
Wide rolls (3–6 m, standard 4–6 m) reduce seams. The membrane side is compatible with standard hot-wedge/hot-air welding; geotextile faces facilitate protection and soil contact.
Structures (by build-up)
One Fabric + One Film (1F-1M) – A nonwoven on one side of a membrane. Balanced performance for general anti-seepage with basic protection.
Two Fabrics + One Film (2F-1M) – Fabrics on both sides of the film. Higher tensile and puncture resistance for water conservancy and municipal works.
One Fabric + Two Films (1F-2M) or Multi-Fabric/Multi-Film – Increased stiffness, barrier redundancy, and protection for difficult subgrades or higher safety factors.
Materials (by membrane resin)
HDPE – Highest chemical/UV resistance; preferred for landfills and exposed reservoirs.
LLDPE – Better flexibility and settlement accommodation.
PVC – Very flexible; suitable for uneven foundations, wetlands, and landscape water.
EVA – Excellent low-temperature performance for cold regions.
Base Fabrics (by geotextile type)
Staple-fiber nonwoven (PP/PET) – Economical cushioning and filtration.
Filament nonwoven (PET/PP) – Higher tensile and creep resistance for demanding sites.
Woven/knitted reinforcement – Adds tear resistance and friction for steep slopes or high loads.
| Configuration | Fabric (g/m²) | Film Thickness (mm) | Notes |
|---|---|---|---|
| 1 Fabric + 2 Films | 100–1000 | Each film 0.10–1.50 | Dual-film build for higher barrier redundancy and stiffness. |
| 1 Fabric + 1 Film | 100–1000 | 0.10–1.50 | Balanced performance for general anti-seepage with protection. |
| 2 Fabrics + 1 Film | 80–600 (each side) | 0.20–1.50 | Higher tensile & puncture resistance; common in water/municipal works. |
| Multi-fabric / Multi-film | Custom | Custom | Built to order for demanding subgrades and safety factors. |
* Values are typical ranges and customizable (width 3–6 m, colors black/white, UV/antioxidant packages available). With stabilized polyethylene film ≈0.2 mm as a baseline, field experience indicates ~40–50 years in clean-water conditions and ~30–40 years in wastewater/leachate environments—meeting long-term dam/landfill service requirements when properly designed, welded, and protected.
Composite Geogrid (Geogrid + Geotextile)
Geogrid composites are widely applied in road and railway foundations, retaining wall backfills, embankment reinforcement, coastal and slope stabilization, and soft-soil improvement projects. They combine reinforcement and filtration in one step, making them highly efficient for large-scale civil works.
Geogrid composite is a high-performance reinforcement material made by bonding or sewing a geotextile layer onto a biaxial or uniaxial geogrid base. The geogrid provides tensile strength and soil confinement, while the geotextile delivers filtration and separation, forming a multifunctional system that reinforces soil while maintaining proper drainage.
Key Features & Explanations
Reinforcement & Load Distribution – The geogrid’s high tensile strength efficiently transfers and distributes loads, improving bearing capacity and reducing deformation.
Filtration & Separation – The attached geotextile prevents soil migration while allowing water flow, maintaining the integrity of the subgrade.
Improved Construction Efficiency – Combined in a single product, it reduces installation steps compared to placing grid and textile separately.
High Durability & Chemical Resistance – Made from PP, PET, or HDPE materials, suitable for long-term use in road and embankment environments.
Adaptable Design – Available in various tensile strengths (20–200 kN/m) and grid apertures to fit different soil conditions.
Main type
Steel-Plastic Geogrid Composite
Reinforced with steel wires encased in high-density polyethylene (HDPE).
Exceptional tensile strength and creep resistance; ideal for heavy-load roads and embankments.
Performs well under repeated traffic loads and long-term settlement.
HDPE Biaxial Geogrid Composite
Made from stretched HDPE sheets forming a uniform grid.
Offers balanced strength in both directions, high rigidity, and resistance to chemical and biological degradation.
Commonly used in roadbeds, parking areas, and foundation reinforcement.
Warp-Knitted Polyester Geogrid Composite
Constructed from high-tenacity PET yarns coated with bitumen or PVC, bonded with a geotextile.
Provides excellent tensile strength, low elongation, and flexibility to fit uneven ground surfaces.
Suitable for slopes, retaining walls, and soft-soil reinforcement.
Fiberglass Geogrid Composite
Composed of alkali-resistant glass fiber strands coated with bitumen or polymer resin, combined with a nonwoven geotextile.
It offers superior tensile modulus, dimensional stability, and excellent thermal resistance, effectively reducing reflective cracking in asphalt pavements.
Mainly applied in road surface reinforcement, asphalt overlays, and highway rehabilitation projects.
Composite Geonet (Geonet + Geotextile)
Three-dimensional composite geonets are widely used in landfill drainage and leachate collection systems, highway and railway subgrade drainage, tunnel and basement waterproofing, and retaining wall or slope drainage layers.
Three-dimensional composite geonet is a new generation of drainage geosynthetic composed of a three-layer geonet core bonded with needle-punched nonwoven geotextiles on both sides.
The geonet core consists of one thick vertical rib and two inclined ribs on the top and bottom, forming a high-flow drainage channel that can quickly discharge groundwater from subgrades or retaining structures.
The structure maintains void stability under heavy loads, blocks capillary water, and provides drainage, isolation, and reinforcement functions in one product.
Key Features & Explanations
Excellent Drainage Capacity – Multi-directional channels allow rapid discharge of water, even under long-term compressive loads exceeding 2000 kPa.
High Tensile & Shear Strength – The triplanar core structure ensures stability and resists deformation under high stress.
Long-Term Flow Stability – The geotextile layers protect the core from soil intrusion, maintaining consistent permeability.
High Compressive Resistance – Withstands much higher loads than conventional geonets while maintaining over 60% thickness after 10,000 hours of creep test at 1200 kPa.
Integrated Filtration & Separation – Nonwoven geotextiles prevent soil clogging while allowing water flow.
Performance Characteristics
At 720 kPa load and 2% gradient, permeability is 2500 m/day, flow rate 13 lpm/m.
Under 1200 kPa load for 10,000 hours, retains > 60% thickness.
Geonet core: carbon black ≥ 2%, density 0.94 g/cm³, tensile ≥ 36.5 kN/m, melt index 1.0 g/10 min, thickness 7.6 mm.
