Advantages

EASY TO INTEGRATE INTO YOUR PROJECT

  • The material used in the manufacturing of our lightweight fill blocks is specifically selected to accommodate your jobsite and its conditions.
  • Blocks and panels are custom-sized and ordered to facilitate field installation and to optimize handling time.
  • To meet project requirements, densities and compressive strengths up to 60 psi (414 kPa) are available.

 

HIGH STRENGTH

  • Highly resistant to bending, shearing and compression.
  • Allows for an even distribution of loads and tensions.
  • Prevents soil subsidence and protects infrastructure.

 

A SUSTAINABLE AND ECONOMIC CHOICE

  • Stable and permanent insulation value.
  • Excellent water and moisture resistance, without loss of efficiency over time.
  • Lightweight, easy to handle and creates no additional load that can affect layout or surrounding structures.
  • An efficient and economic solution.
