  • Tensile strenght MD/CMD
  • Elongation
  • Resistance to static breakdown (CBR-test)
  • Protection

ADVANTAGES OF GEOCOMPOSITE
  • Good mechanical features which provides excelent mechanical separation
  • Provides efficient protection of HDPE membrane
  • Low waterpermeability
  • Exceptional resistance to damage during installation
  • Increases stability
  • Easy handling and instalation
  • Environmentally neutral
  • Extend elongation
GEOCOMPOSITE APPLICATION:
Geocomposite Martin MAT sandwich PP 450 with special membrane for tunnels, cannals and landfills has direct application on the wall and base of tunnel (pneumatic riveting). Prevent water dripping from walls of tunnel. High CBR provides protection of HDPE membrane.
 WARNING at installing GEOCOMPOSITE:
  • Rolls (tapes) must not be longer than 50 yards in setting
  • Implemented geocomposite must not have wrinkles during installaion
  • Overlapp must be min 30 cm
  • On geocomposite joints must be riveted with noncorrosive nails ( 1 n/m) or by sewing of compounds
  • Resistante in alcaline environment
