What is Benefil?


  • A unique, pre-expanded structural resin that becomes super-light in weight.
    It is produced on site form a liquid base-slowly or at much higher volumes dependent on the need.
    It can be poured, pumped or injected into holes, voids and interstitial spaces-or laterally over long distances.
    Pre-expanded before placement and whit a short gel time, Benefil will displace residual liquids and can be applied underwater.
    Not a liquid, not a solid, it flows only under applied pressure-unit it gels and begins to set hard. The slump characteristics are controllable and the material does not run away.
    Benefil is environmentally neutral, inert, solvent free, non-toxic and non-flammable. It can be recycled for agricultural purposes and can be disposed of in landfill.
