Terrex NW Geotextile is a range of staple fibre, needle punched and thermally bonded non-woven geotextiles designed specifically to offer optimum performance per unit weight.
Terrex NW geotextiles perform the functions of separation and filtration in the construction of subbase granular layers. This separator / filter function prevents the intermixing of granular subbase layers and the passage of stone particles which could cause the failure of the surface or pavement structure.
Terrex NW geotextiles are non-woven, needle punched, heat treated fabrics designed to offer optimum performance per unit weight, with high mechanical and hydraulic properties making them the ideal choice for separation and filtration applications.
The resulting mechanical robustness and excellent hydraulic properties make Terrex NW geotextiles an ideal choice for filtration and separation applications, including as a general purpose separator under site access roads and hard-standing areas, as a separation and strengthening layer under new roads and as a filter medium in the construction of French drains or granular drainage blankets.
Terrex NW geotextiles offer many advantages; including uniform tensile strength in all planes through the geotextile fabric, a wide range of CBR puncture strengths, excellent water flows normal to the plane, consistent pore opening sizes for use with a wide range of soil types and hydraulic properties suited to the demands of everyday filter separators.
The use of ABG Terrex NW geotextile may offer cost savings on the project by helping reduce the requirement for fill materials and by minimising future maintenance.
