Looking for advanced waterproofing and soil separation performance in a single material?
The Geomembrane Geotextile Composite Sandwich structure offers superior barrier protection, reinforcement, and filtration—ideal for landfills, ponds, tunnels, mining sites, and more.
By combining HDPE/LDPE geomembrane layers with nonwoven geotextile fabrics, this composite sandwich provides multi-layer durability with a unified solution that saves time, labor, and cost.
? What Is a Geomembrane Geotextile Composite Sandwich?
A Geomembrane Geotextile Composite Sandwich is a multi-layer geosynthetic product made by thermally bonding one or both sides of a polyethylene geomembrane with high-strength nonwoven geotextiles.
This creates a hybrid material with:
Impermeability (via the geomembrane core)
Drainage & filtration (via the geotextile layers)
Tear resistance & flexibility (via the layered structure)
Think of it as a “sandwich” where the geomembrane acts as the waterproof filling, and geotextiles as the protective bread layers.
? Typical Structure Options
1 Layer Geotextile + 1 Layer Geomembrane (Single-sided composite)
1 Geomembrane + 2 Geotextile Layers (Double-sided composite sandwich)
Customized thicknesses from 0.3mm to 2.0mm, fabric weights from 100g–600g/m²
Note: We offer both needle-punched polyester and polypropylene geotextiles, bonded with HDPE, LDPE, or EVA membranes depending on your project.
?️ Key Features & Benefits
? 1. Superior Waterproofing
The central geomembrane layer provides exceptional impermeability—ideal for preventing seepage and protecting groundwater.
? 2. High Strength & Flexibility
The nonwoven geotextile layers increase puncture resistance, tensile strength, and allow for easier installation even on uneven terrain.
? 3. Enhanced Drainage & Filtration
The geotextile sandwich structure facilitates drainage while also acting as a filter—perfect for containment systems with fluctuating hydrostatic pressure.
⛰️ 4. Slope Stability
Ideal for use on steep embankments or leachate slopes, the textured surface (optional) adds friction and anchoring performance.

? Real Customer Reviews
⭐⭐⭐⭐⭐
“We used the geomembrane geotextile composite sandwich for a mining leach pad project in South Africa—no leaks, easy to install, and zero material failures even under harsh chemical exposure.”
— James K., Site Engineer, GeoShield Projects Ltd.
⭐⭐⭐⭐☆
“Much better performance than traditional HDPE liner alone. The sandwich composite handled both waterproofing and filtration in a single layer—saved us time and money.”
— Elena W., Project Manager, Aquatech Environmental
⭐⭐⭐⭐⭐
“High-strength and incredibly tough! We had a steep slope retention application, and this product held up beautifully during monsoon rains.”
— Naveen R., Civil Contractor, GreenEarth Infra
