Grout

In Plain English

A cement-based material used to fill gaps — between tiles, masonry joints, or under equipment base plates.

Definition

A cementitious mixture of cement, water, and sometimes sand, used to fill joints in masonry, anchor bolts, and post-installed hardware, or to create a bearing surface under base plates and equipment. Non-shrink grout is used where dimensional stability is critical, such as under structural column base plates. In tile work, grout fills the joints between tiles.

Example

Non-shrink grout was pumped under all structural steel column base plates after the steel was plumbed and aligned.
