|Overview Drilling & Grouting|
Grouting, as applied to civil and geotechnical construction, involves the injection under pressure of a liquid or suspension into the voids of a soil or rock mass or into voids between the soil or rock mass and an existing structure. The injected grout must eventually form either a solid or gel within the injected voids.
The purpose of pressure grouting a soil or rock mass is to improve the strength and durability of the grouted mass and/or to reduce its permeability.
Grouting applications relating to permeability reduction include:
Improvement of Mechanical Properties
Types of grouting done, and specifically by the Judy Company, include:
Grouting is a valuable tool in geotechnical construction and the type of grouting chosen should be determined by an evaluation of the pertinent aspects of a problem including engineering needs, subsurface conditions, materials and access available, and economic considerations.
