grouting
Quick Summary
Grout is a type of thin mortar used to fill spaces, particularly the joints in masonry. It is also used for similar purposes with other materials, such as a mixture of cement and water or chemicals that solidify. Mortar, in general, is a building material that bonds elements like brick, stone, or concrete blocks together. It is made from sandy material mixed with cement and water, creating a plastic substance that can be applied with a trowel. Mortar hardens to distribute structural load and create weathertight joints.12
