To stabilise coastal structures, protect landfill lining systems, and reinforce ground in the road, water, coastal, and waste sectors, Terrafix Geo Textile 2m Wide (Texcel R) provides a high-elongation barrier that minimises installation damage and maintains close soil contact. This non-woven staple fibre geotextile is manufactured in Australia from 100% virgin polyester fibre to deliver consistent mechanical and hydraulic performance under demanding site conditions.
Protection for impermeable lining systems
When used in landfill lining systems, the geotextile cushions the barrier by significantly reducing the physical forces placed on impermeable liners. This cushioning effect protects the liners from puncture and stress in both the short term during construction and over the long term under high waste loads. The high elongation properties allow the fabric to conform closely to uneven ground profiles, securing effective soil contact and interface stability without tearing.
Tested durability in harsh environments
Texcel R is engineered to retain its mechanical and hydraulic properties when exposed to environmental stresses, chemicals, and construction wear. The 100% virgin polyester fibres are tested under Australian Standards (AS 3706) to verify performance against physical degradation. The material resists abrasion from moving aggregates, retains more than 90% of its strength when exposed to hydrocarbons such as diesel, and maintains its filtration and permeability paths under high pressure.
Numbers that matter
- 100% Virgin Polyester Fibre: Provides consistent chemical resistance and physical stability without recycled contaminants.
- >90% Hydrocarbon Resistance (AS 3706.12): Retains almost all structural strength when exposed to diesel, making it suitable for waste sectors and roadside environments.
- CBR Burst Strength (AS 3706.4): Ranges from 2,750 N (400R) up to 8,850 N (1200R) to resist puncture from sharp aggregates during backfilling.
- Pore Size O₉₅ (AS 3706.7): Standardised at ≤75 µm across all grades to prevent fine soil migration while allowing water to pass.
- Flow Rate @ 100mm Head (AS 3706.9): Ranges from 141 L/m²/s (400R) to 30 L/m²/s (1200R) to match the drainage requirements of the specific site design.
Limitations
Site-specific environmental conditions can affect the required mechanical and hydraulic specifications. Contractors and engineers must verify the correct Texcel R grade (400R, 600R, 900R, or 1200R) to ensure the tensile strength, CBR toughness, and flow rates match the project design. Standard engineering assessments should be completed prior to installation to account for local soil chemistry, slope stability, and hydraulic loads.
Are all Texcel R grades hydraulically and mechanically identical?
No. The current manufacturer TDS lists different strength, permeability and flow values for 400R, 600R, 900R and 1200R. Select the grade specified by the project design.
