Fluidized thermal backfill specification
WebWhen the calculated soil thermal values are not adequate, a fluidized material, consisting of raw materials used in the production of ready-mix concrete, referred to as Fluidized Thermal Backfill, is engineered to aide in this heat transfer. Foam Fill Mix for Pressure Grout Rock Solid was contacted to design a mix for a Pressure Grouting company.
