Where Fine grout is used

A high-slump cement–sand grout (no coarse aggregate) for pouring into narrow grout spaces and small block cavities. Placed wet enough to flow around reinforcing bar.

Grout is placed at a high slump so it flows fully around reinforcement and fills the cavity without voids. It is not the same as mortar, and it is not the same as tile grout.

Need quantities? The volume calculators give the cubic yards, cubic metres and bag counts for the pour this mix goes into.
