Needle punched nonwoven geotextile for separation, filtration and protection
Bontec SNW are needle punched specially bonded geotextile designed to offer outstanding performance at a lower thickness compared to traditional protection geotextiles. The principal functions of SNW are protection, separation and filtration.
Through the optimum combination of polymer and our unique production technology, our SNW product range is the lower thickness alternative to standard geotextiles for protection of impermeable membranes in landfill and reservoir construction as well as for coastal protection from erosion below rock and concrete defences.
Specially engineered SNW product types with UV additives are available for geobags for coastal or riverbank protection and other applications.
