TerraFlow®
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.

Benefits
Superior performance when used with sulphide/sulphate-bearing materials commonly found in mine tailings
Potential binder reductions in some circumstances
Allows for more efficient and cost-effective backfilling in underground mines
Optimizes use/reuse of material, including cementitious materials
Elimination of tailing detention and/or disposal requirement
Pre-blended before arriving on site to promote maximum working efficiency and reduce site equipment
Blend proportions may be varied according to specific requirements as determined by preliminary testing
Saves energy and natural resources
Superior performance in clay-bearing soils
