Intrusion-Aid FG is a Mid-Range Water Reducing Grout Fluidifier, per ASTM C937. Intrusion-Aid FG is ideal for a standard augercast grout in favorable soil conditions. It provides the necessary water reduction (fluidity) at typical water-to-cement ratios. The balanced formula minimizes bleed and segregation, while improving workability. It is ideal for augercast grout with a moderate-to-high compressive strength requirement. Intrusion-Aid FG meets the requirements of a Type D, water reducing and retarding admixture according to ASTM C 494.
