The specialist nonwoven geotextiles offered by TCS Geotechnics are specifically designed to provide separation, filtration, and protection functions. The geotextiles are manufactured by mechanical bonding (needle punched) and/or thermal bonding or treatment. The excellent combination of high elongation and tensile strength -exhibited in particular by the needle-punched materials – provide these nonwoven geotextiles with excellent resilience and make them highly resistant to installation damage. Manufactured to the highest quality, these nonwoven geotextiles attain excellent standards of mechanical performance and durability and products are readily available from stock which comply with the requirements of BS8661:2019 – Geotextiles – Guidance for specification for basic separation and filtration functions.
The TCS Geotechnics Non Woven Geotextile range (TNW1000T to TNW3000F) are high quality polypropylene mechanically bonded (needle punched) geotextiles. As indicated above, these mechanically bonded materials are particularly robust with respect to potential installation damage as the combination of tensile strength and extensibility allows the material to flex and accommodate stress and strain whilst inhibiting puncture. These materials have CBR puncture resistance ranging from approximately 1400N to 3600N. These needle punched non woven geotextiles are typically applied to provide separation and filtration, for example beneath road sub-base or encapsulating drainage blankets or trench infill. The 3000F is also regularly used for lighter duty puncture protection to impermeable barriers, for example in attenuation SUDS systems.
TCS also offer heavier duty mechanically bonded (needle punched) non woven geotextiles with CBR puncture values up to 14000N. These materials provide efficient protection or filtration in even the most demanding situations, for example protecting impermeable landfill lining to prevent contaminant leakage or as part of coastal defence works beneath rip-rap to avoid washout.
TERRAM NON WOVEN GEOTEXTILE
Terram non-woven geotextiles are manufactured from UV stabilised, high-tenacity, virgin polypropylene fibres that have been both mechanically and thermally calendared to provide high strength and excellent abrasion characteristics. These geotextiles are engineered to provide high strength and high elongation at break to ensure excellent resistance to damage during construction. Terram standard geotextiles are manufactured to performance properties, not weight, sufficient fibre will be added to achieve these properties. Manufactured from high tenacity UV stabilised virgin polypropylene fibres which have been heavily drawn to ensure excellent long-term durability in all soil types. Manufactured using a randomly orientated web to provide completely isotropic properties, ensuring that high strength is not limited to a single direction. Excellent uniformity with high permeability and low pore size for optimised soil filtration.
