Marilyn Barrier

Marilyn Barrier – AS is a high performance liquid foaming agent based on special biodegradable anionic surfactants, studitied to treat clayed and sandy grounds in tunnels dug with full-section mechanical cutter.


  • Reduced permeability
  • Higher stability during excavation
  • Lower cohesion (for clayed ground)
  • Lower friction and internal abrasivity, with less power consumption, easier waste transport operations, lower wear of mechanical components
  • Better plastic deformation


(at +20 °C)

Appearance : uniform, clear liquid
Specific Gravity : 1.04 ± 0.02 kg/l
Solubility : completely soluble in water
