Needle punched nonwoven geotextile for protection
Bontec Protec is a range of needle punched nonwoven geotextiles optimally designed to offer greater thickness and elongations compared to standard needle-punched nonwovens. This makes them well suited for protection and drainage applications where a thick cushioning layer and high elongation are key requirements for the design.
Typical areas of use include the protection of valuable pipeline coatings during backfilling, as an erosion control layer under rock armour in coastal defence projects, and as a protective cushion layer in landfills and reservoirs. Due to its high thicknesses, Protec nonwoven geotextile will provide higher water flow in the plane values compared to standard needle-punched nonwoven geotextile, allowing it to also function as a drainage layer in some applications.
- Tensile strengths ranging from 20 kN/m to 100 kN/m combined with elongations of 80% or higher
- Available in weights from 300 to 1500 g/m²
- Fabric thicknesses up to 10 mm
- CBR puncture values up to 20 kN
- Produced using 100% virgin polypropylene staple fibres
- Project specific dimensions are available on request
- Coastal engineering
Features and benefits
- Minimal 100 year durability
- Maximum performance to cost ratios
- High elongation
- High damage resistance even for the most demanding fill types
- Excellent resistance to acids and alkalis at ambient temperatures
- High UV resistance for requested product types
- High biological resistance
- High puncture resistance and tensile strength
- Outstanding protection to membranes and liners (for landfills, reservoirs)
- High permeability and fine pore size
- Ideal for more demanding applications – for example coastal engineering
- Significant reduction of carbon footprint and costs compared to traditional methods
Also available: a flame-retardant version, very well suited for use in protection and drainage applications where there is a high risk of exposure to flames, such as tunnels.
