Description
Polyester filament nonwoven for separation, filtration, drainage and protection layers. BRELVO can coordinate available constructions against drawings and project requirements; a final grade must be confirmed for each enquiry.
Applications
- Road and rail subgrade separation
- Filtration and drainage beneath granular layers
- Cushioning next to a designed liner system
