Firth Flowable Fill Engineered Concrete

Firth Flowable Fill is a flowable mix that can be used as a substitute for conventional granular hardfill materials. It can be delivered by chute or pump, making it ideal for spaces with restricted access.

  • a low-strength mix of sand, cement, flyash and water
  • can be placed into large areas directly by chute or pump
  • ideal for backfilling utility trenches, for structural fill under foundations or floor slabs, or filling disused storage tanks
  • mix can be adjusted to suit your requirements
  • compressive strengths of 1 - 2.5 MPa after 28 days

Thermal Bedding

Thermal Bedding is a specialty solution for filling around heavy electrical conduiting. It shares the benefits of Flowable Fill™ but its higher strength and improved thermal conductivity gives greater protection to key services.
