TERRAM Robust - nonwoven geotextiles to protect, separate and filter

TERRAM Robust non-woven, needle-punched geotextiles are used to provide protection, separation and filtration functions in a variety of applications. They are manufactured from UV-stabilised, high-tenacity virgin polypropylene fibres that have been mechanically entangled to provide high-strength, high-extensibility, high-loft and excellent abrasion characteristics.

Applications

Robust geotextiles are typically used for the protection of impermeable membranes in landfill basal areas, side walls and caps, tailing lagoons, reservoirs, balancing ponds, reed beds, artificial lakes to prevent soil erosion from beneath rock armour and pre-cast concrete revetments, sea shores, rivers and water channels, lakes and reservoirs.

Application areas include environmental engineering, SuDS, coastal sites, waterways, pipeline and utilities.

Key features and benefits

• Manufactured from inert high-tenacity virgin polypropylene fibres to give excellent long-term durability in all soil types

• High static and dynamic puncture resistance ensures a low risk of damage during and post construction

• Random orientated web with isotropic properties provide the same strength, permeability and filtration in all directions

• High elongation at break maintains separation and filtration functions under load, particularly in soft and variable ground conditions.

• High loft gives excellent cushioning, protecting underlying geomembranes from puncture

• Mechanical entanglement of the fibres produces an extremely flexible material, ensuring full contact with highly undulating ground contours maintaining the protection, filtration and separation function
