nonwoven bontec® Protec for protection

Discover nonwoven bontec® Protec, an advanced needle-punched nonwoven geotextile designed to provide superior protection. This range is well-suited for applications where a strong protection layer is crucial.

bontec® protec finds typical use in protecting valuable pipeline coatings during backfilling, serving as an erosion control layer under rock armor in coastal defense projects, and acting as a protective layer for geomembrane in landfills and reservoirs.

Technical details include tensile strengths ranging from 22 kN/m to 80 kN/m, weights from 300 to 1200 g/m², fabric thicknesses up to 10 mm, and CBR puncture values up to 15 kN. Produced using 100% virgin polypropylene staple fibers, Protec also accommodates project-specific dimensions upon request. 

Functions include protection, separation, and filtration. Elevate your project’s performance with Bontec Protec, setting new standards in geotextile innovation. 

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

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
  • 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
  • Bontec Protec is needle-punched from 100% virgin polypropylene fibres
  • Bontec Protec offers 80% to 120% elongation at break to suitably cover voids and provide excellent puncture resistance


bontec® protec is needle-punched from 100% virgin polypropylene fibres permitting 75% to 85% elongation at break. For a mass per unit area of 1000 g/m2, its static pyramid puncture resistance is 5.5 kN, and its dynamic perforation 0mm.

bontec® protec 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, bontec® provides superior puncture resistance and are ideal for liner protection, basal geomembrane protection and coastal protection applications.

Installation technique

  • plan layout to limit cutting out
  • prepare a flat, graded, compacted base with no protruding elements or geomembrane support
  • unroll the product on the ground with a pole passed through the reel, or unwind by hand, or suspended from a lifting beam
  • the overlap depends on the supporting soil; on a stable, graded soil 30cm; on a soft soil 60cm to 1m
  • the textile can be stitched together or “welded” with a hot air / gas gun
  • cut out the product using a cutter or scissors, wearing gloves


bontec® protec is available in rolls 5.25m wide x 100m or 4m x 100m. Other sizes on request.
