About TerraFlow

TerraFlow is a specialized engineered blend of cementitious and other construction materials that allows for a more efficient and cost-effective solution for backfilling in underground mines. It has also been successfully used in a number of soil mixing applications to improve the geotechnical requirements of native soils.

 

TerraFlow is also specifically designed for paste or rock backfill of underground slopes and can reduce total binder consumption when compared to Portland cement. Its formulation has also been found to be ideal for deep soil mixing operations, particularly where highly plastic, clay-bearing soils are encountered.
