Intrusion-Aid FG+ is a water reducing and stabilizing admixture for high strength neat grout (non-sanded). It is a Grout Fluidifier meeting the requirements of ASTM C937. Intrusion-Aid FG+ improves fluidity at low water-to-cement ratios, reduces or eliminates bleed water and provides plastic expansion to compensate for shrinkage prior to hardening. FG+ is commonly used at low water-to-cement ratios between .39 and .45 for high compressive strength. Treated grout is fluid, stable and easy to pump. Shrinkage compensation and bleed reduction ensures voids are filled completely.
