What is grouting in construction?
Grouting in civil engineering refers to the injection of pumpable materials into a soil or rock formation to change its physical characteristics. It is one of the ways ground water can be controlled during civil engineering works.
How does compaction grouting work?
Compaction grouting involves the injection of a low slump, mortar grout to densify loose, granular soils and stabilise subsurface voids or sinkholes.
Which material is used in grouting?
Cementitious grouts have as their main component Portland cement, plus filler particles of different sizes, a water-retentive additive, and colored pigments.

How many types of grout are there?
There are four basic types of grout: unsanded, fine sanded, quarry type, and epoxy. Unsanded grout : This is used for wall tiles where the grout joint is less than 1/8” wide. Finely sanded grout: This is used for floor tiles where the joints are 1/8” to 3/8” wide.
Why grouting is used?
Grout offers a number of valuable benefits: It gives your floor or wall a crisp finished appearance. it helps keep dirt and debris from getting in between and under your tile. It adds rigidity and strength to the tile installation.
Which grout is best for bathrooms?

What is compensation grouting?
Compensation or fracture grouting is the injection of a cement slurry grout into the soil creating and filling fractures that then lift the overlying soil and structures.
What is fracture grouting?
Compensation grouting, also known as fracture grouting, is the injection of a cement slurry grout, hydrofracturing soil, creating lenses. The lenses compact surrounding soil and then lift the overlying soil and structures.
Is grout a cement?
Grout is generally a mixture of water, cement, and sand and is employed in pressure grouting, embedding rebar in masonry walls, connecting sections of pre-cast concrete, filling voids, and sealing joints such as those between tiles.
