  • Tensile strenght MD/CMD
  • Elongation
  • Resistance to static breakdown (CBR-test)
  • Hole size
  • Waterpermeability
  • Durability

ADVANTAGES OF GEOCOMPOSITE
  • Good mechanical features which provide efficient separation
  • Excellent filtering properties
  • Ideal waterproof
  • Exceptional resistance to damage during implementation
  • Increases the stability of soil
  • Easy handling and instalation
  • Environmentally neutral
  • Minimum elongation
GEOCOMPOSITE APPLICATION:
Martin M-A-T sandwich GRID 40x40 100/100 has direct implementation, on the muddy soil, and on the soil which has high moisture concentration. It also reducing the usage of filling material up to 30%.
 WARNING at installing GEOCOMPOSITE:
  • Rolls must not be longer than 50 m at installation
  • Implemented geocomposite must not have wrinkles during installation
  • Overlapp must be min 30 cm, for installing on the muddy soil or in the water min 100cm
  • On slopes and curves it is mandatory to rivet geocomposite ( 1 rivet/m) or sewing compounds
  • Durability > 50 years.
