Product Overview
Nonwoven Geotextile Fabric Solutions
Nonwoven Geotextile is an essential synthetic material for modern civil, hydraulic, and environmental engineering. We produce it using a needle-punching process from 100% virgin polyester (PET) or polypropylene (PP) fibers. This creates a robust, permeable fabric designed to solve soil stability and drainage challenges.
Key Engineering Functions
Tianyuan’s nonwoven geotextiles provide four critical functions for your projects:
- Filtration: It allows water to pass through while retaining soil particles. This prevents the internal erosion of soil structures.
- Separation: It prevents the mixing of different soil layers, such as subgrade and aggregate. This maintains the structural integrity of roads and railways.
- Drainage: The fabric collects and transports excess water within its plane. This ensures effective relief of hydrostatic pressure.
- Protection: It acts as a cushion to protect geomembranes and other liners from mechanical damage and puncture.
Why Choose Tianyuan Geotextile>=
As a dedicated manufacturer in China, Tianyuan offers high-performance geosynthetics for global projects:
Seamless Large Widths
We provide geotextile rolls with a seamless width of up to 8.0 meters. This significantly reduces the number of overlaps and material waste in large-scale engineering projects.
High Puncture Resistance
Our needle-punching technology ensures the fabric can withstand the rigors of heavy machinery and sharp-edged aggregates during construction.
Chemical & Biological Stability
Our fabrics resist naturally occurring soil chemicals, acids, and alkalis. This ensures a design life that matches the infrastructure it protects.
Tianyuan Waterproof supports international engineering firms and distributors with technical documentation, including product-specific TDS and MSDS. Applicable certificates and test reports depend on the product configuration and destination market; confirm the required documentation before specification.
Applications
Transport Infrastructure
Essential for soft ground stabilization in roads, railways, and airport runways to improve subgrade bearing capacity.
Drainage Systems
Acts as a filter layer for subsoil drainage, landscape projects, and sports fields to maintain water flow.
Environmental Projects
Protective layer for geomembranes in landfills, tailings treatment, and hazardous waste containment.
Tunnel & Subway Works
Provides drainage and structural protection for underground tunnels, stations, and culverts.
Key Benefits
Superior Filtration
Effectively allows water to pass through while trapping fine particles, maintaining the stability of soil structures.
High Tensile Strength
Needle-punched nonwoven technology provides exceptional strength in both longitudinal and transverse directions.
Aging & Corrosion Resistance
Specially formulated to withstand UV radiation and chemical exposure, ensuring a long engineering service life.
Excellent Puncture Resistance
Protects geomembranes and other liners from sharp objects in the subgrade during and after construction.

Installation Guide
Surface Preparation
Clear the subgrade of sharp objects, large stones, and debris. Level the surface to ensure uniform support.
Fabric Deployment
Unroll the geotextile flat on the prepared surface. Avoid dragging and ensure the fabric is free of wrinkles.
Overlap Management
Overlap adjacent rolls by at least 30-50cm. For critical applications, thermal bonding or sewing is recommended.
Placement of Overlays
Carefully place the next layer (soil, stone, or geomembrane) over the geotextile to avoid displacement or tearing.
Packaging & OEM
Durable Roll Packing
Each roll is wrapped in a heavy-duty, UV-stabilized woven bag to protect against moisture and handling damage.
Optimized Roll Sizes
Standard widths of 5.8m and 7.0m are optimized for 40ft container loading to reduce shipping costs.
Clear Identification
Rolls are labeled with type, weight, width, and batch number for easy on-site traceability.
OEM & Branding
Custom labels and branding options are available for project orders and long-term distribution partners.

Frequently Asked Questions
What is the difference between PET and PP nonwoven geotextile?
PET (Polyester) has a higher melting point and better UV resistance, making it suitable for exposed or high-temperature environments. PP (Polypropylene) has superior chemical resistance, especially in highly alkaline soils, and is generally more cost-effective for underground drainage.
How do I choose the right weight (GSM) for my project?
The choice depends on the application. 100-200g is common for filtration and light separation; 300-500g is used for geomembrane protection and road subgrade; 600-800g is for heavy-duty hydraulic and landfill engineering.
Is this fabric UV resistant?
Yes, our geotextiles are treated with UV stabilizers to ensure they maintain their strength during the construction phase when exposed to sunlight. However, long-term performance is best achieved when covered by soil or a liner.
Can nonwoven geotextile be used for drainage?
Absolutely. Its needle-punched structure creates a three-dimensional pore network that allows water to flow freely while preventing fine soil particles from clogging the drainage system.
Does Tianyuan provide testing reports?
Yes, every batch undergoes strict internal QC testing. We also provide test reports based on ASTM or ISO standards upon request for project compliance.
