MasterFlux 815
Cementitious High-Strength Non-Shrink Precision Grout for Deep Pour Applications (formerly MasterFlow 815)
How Does MasterFlux 815 Work?
MasterFlux 815 is a non-shrink, natural aggregate precision grout for deep pours, formulated to provide ample working time when mixed and placed at a flowable consistency.

MasterFlux 815 is used for all precision, non-shrink grouting applications with thick layers and clearances of 50mm, including:
Equipment baseplates, soleplates, and columns
Precast concrete panels, beams, and columns
Grouting thick pour applications up to 500mm thick
Concrete repair applications where a form and pour material is required
Applications requiring high early compressive strengths and high ultimate compressive strengths
What Are the Unique Features of MasterFlux 815?
MasterFlux 815 contains specially graded natural aggregate and provides high early and ultimate compressive strengths. MasterFlux 815 is generally used for deep pour applications between 50mm and 500mm.
What Are the Benefits of MasterFlux 815?
High strength – provides good early and ultimate strengths, which ensure quick return to service and long-term durability
Non-shrink – hardens free of bleeding, settlement, and drying shrinkage when placed at flowable consistency
Ample working time – remains placeable even at high ambient temperatures
Flowable consistency - able to be pumped with grout pump
Non-staining – free of metallic aggregate
Complies with codes – meets requirements of AS1478.2-2005 and the non-shrink requirements of ASTM C1090 and CRD-C 621, Corps of Engineers Specification for Non-Shrink Grout
Provides complete non-shrink performance when tested in accordance with a simulated bedplate technique
