Specification of MasterFlow 815 Cementitous Grouting MBS
MATERIAL DESCRIPTION
MasterFlow 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. MasterFlow 815 contains specially graded
natural aggregate and provides high early and ultimate
compressive strengths. MasterFlow 815 is generally
used for deep pour applications between 50mm and
500mm.
AREAS OF APPLICATION
MasterFlow 815 is used for all precision, non-shrink
grouting applications with thick layers and clearances of
50mm or more including:
• Equipment baseplates, sole plates & 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
CHARACTERISTICS AND BENEFITS
• 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
