Permeation Grouting

In permeation grouting, sandy soil is densified by injecting it with a special liquid material. This material permeates the space between the granular soils and thus locking them together. In some cases, certain depth zones of the strata are targeted. Cementious ultra fine grouts and chemical solutions are designed for the application.

Typical uses of permeation grouting include:

• Adding bearing capacity to soils to achieve higher loads
• Earth retention during excavation along a structure or pit
• Obstructing water movement through soil
