Nonwoven needle-punched geotextiles designed to provide superior protection and drainage capabilities. This range is optimised for increased thickness and elongation compared to standard needle-punched nonwovens, making it well-suited for applications where a thick cushioning layer and high elongation are crucial. 

Its typical use is as an erosion control layer under rock armor in coastal defense projects, and acting as a protective cushion layer in landfills and reservoirs. Due to its elevated thickness the range offers higher water flow in the plane values compared to standard needle-punched nonwovens, allowing it to function as a drainage layer in specific applications. 

Technical details include tensile strengths ranging from 20 kN/m to 100 kN/m, elongations of 80% or higher, weights from 300 to 1500 g/m², fabric thicknesses up to 10 mm, and CBR puncture values up to 20 kN. Produced using 100% virgin polypropylene staple fibers, Protec also accommodates project-specific dimensions upon request.

Functions include protection, separation, and filtration. Additionally, a flame-retardant version is available, well-suited for protection and drainage applications where there is a high risk of exposure to flames, such as tunnels. 

The nonwoven protection geotextiles are engineered to provide unrivalled CBR puncture resistance and tensile strength, offering maximum protection at optimum cost levels.


  • landfills, reservoirs, groundworks, and coastal engineering
  • protection of geomembranes
  • filtration separation under rockfills

Terrex SNW protection geotextiles

Needle punched geotextile engineered to provide maximum CBR, puncture resistance and tensile strength at optimum cost.


  • minimal 100-year durability
  • optimal performance-to-cost ratios
  • high elongation, damage resistance for demanding fill types
  • excellent resistance to acids and alkalis at ambient temperatures
  • high UV resistance, biological resistance, high puncture resistance, tensile strength
  • outstanding protection to membranes and liners (for landfills, reservoirs), high permeability, fine pore size
  • suitability for more demanding applications like coastal engineering
  • needle-punched from 100% virgin polypropylene fibres
  • 80% to 120% elongation at break to suitably cover voids and provide excellent puncture resistance


Needle-punched product manufactured from 100% virgin polypropylene fibres permitting 80% to 120% elongation at break. For a mass per unit area of 700 g/m2, its static pyramid puncture resistance is 3 kN, and its dynamic perforation 0mm.

The geotextiles are used in many civil engineering and construction applications including the construction of highways, rail permanent way, landfill, coastal defences and sustainable urban drainage systems. The geotextiles provide a thick filter / protection fabric that offers outstanding performance at minimum weight. When compared to other needle punched geotextiles of similar weight, the superior puncture resistance provides an ideal option for liner protection, basal geomembrane protection and coastal protection applications.
