Needle punched nonwoven geotextile for protection
Tipptex H-Protec & BNT nonwoven are 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, the non-treated 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.
