Our geotextiles used for industrial, civil engineering and construction are manufactured according to ISO 9001 quality standards to meet the strict mechanical and hydraulic requirements necessary to solve geotechnical and hydraulic engineering challenges. Each batch is tested and certified by the factory's modern textile testing laboratory. Production samples are regularly tested by independent laboratories.
Non-woven Geotextiles
We supply a range of both polypropylene and polyester geotextiles used for separation, filtration and reinforcement applications. These include: needle punched staple fibre geotextiles; continuous filament spunbonded geotextiles; stitch reinforced non woven fabrics and thermal embossed fabrics suitable for reusable carry bags with an exceptional degree of uniformity.
The company's modern equipment, ISO9001 accreditation, continuous development and investment programme delivers geotextiles manufactured to the highest international standards. Each batch laboratory tested and certified.
Our highly uniform non-woven fabrics are used in Australian coating factories to manufacture termite barriers, waterproof liners and high performance petrolatum wax tapes.
Continuous filament, spunbond polyester geotextiles
Produced according to ISO 9001 quality standards on Italian looms using all new polyester resin this continuous filament needle punched geotextile is used in separation, filtration and reinforcement applications. Heat bonding can be applied to further strengthen the fabric.

Staple fibre, needle-punched geotextiles
Our polyester and polypropylene staple fibre geotextiles are manufactured according to ISO 9001 quality standards needle punched from the top/bottom/top and heat bonded to achieve a strong and stable matrix.
These non wovens have excellent physical and hydraulic properties and offer a cost effective alternative for separation, filtration and protection applications. The abrasion resistance of staple fibre, non woven geotextiles is particularly beneficial when only gravel fills are available. A staple fibre geotextile delivers high through flow rates and excellent drainage performance while preventing fines migration. Their high elongation properties withstand severe installation damage and they are chemically resistant to naturally occurring soil environments.
Paving Fabrics
Polyester, non woven, continuous filament, fibre-fired paving fabrics significantly reduce reflective cracking when used in pavements on concrete roads, for repairing existing road surfaces and for the construction of new roads. When saturated with bitumen these geotextiles provide stress relief, waterproofing and reduce reflective cracking in new and existing paved roads.

Advantages :
- Manufactured to ISO9001 standards using new polyester spun bonded continuous fibres, mechanically bonded by needle punching and fibre-fired.
- High melt temperatures. These pavement fabrics do not melt at temperatures below 250oC.
- The fibre-firing process enhances the stability of the fabric when hot bitumens/asphalt are applied. When exposed to hydrocarbons present in bitumen, the fabric is very stable and does not shrink or distort.
- Very strong with high tear and puncture resistance. Spunbonded, needle punched technology results in higher tensile strengths for the same weight of fabric.
- Minimal surface variation allows the paving fabric to rapidly absorb the applied bitumen and form a tight barrier with the road surface.
- Ease of use. Having one side of the material fibre-fired ensures that the paving fabric will not be lifted by vehicle tyres. Yuan Da's own manufacturing process guarantees the quality of the material when it is laid.
Reinforced Stitched Non-woven Polyester Geotextile
High strength reinforced stitched non-woven polyester fabrics are both lightweight and offer exceptional strength. They are custom manufactured to meet specialist requirements such as stabilising coastal areas.

Heavy Duty Reinforced Stitched Non-woven Polyester Underlay
This heavy-duty, high tensile reinforced stitched non-woven polyester offers superior protection for liners from abrasion and prevents long term damage caused by indentation from stony soils under high static loads. The underlay consists of two layers of non-woven polyester fabric, needle-punched to an inner layer of reinforced stitched polyester fibres.
Traditionally subgrades had to be well compacted and offer an even grade, free from sticks, stones and protrusions to prevent any damage to the liner. This heavy duty reinforced stitched non-woven polyester underlay is an ideal rock armour underlays for stormwater outfalls, marine scour pads, pond and dam geo-textile underlays, woodchip underlay pads and separation layers. It also delivers improved performance when welding HDPE on undulating surfaces.
