This three hour online course discusses guidelines and criteria for improving ground conditions by chemical and particulate grout injections. Grouting methods include permeation, compaction, slurry, jet grouting, deep soil mixing and mini-piles. Grouting can be used to modify soil properties in order to improve performance for slope stability, bearing capacity, seepage instability, groundwater control during construction, excavations in tight places, tunneling and to create subsurface groundwater barriers. Grouting can be used to stabilize sub-grade soil ranging from expansive clays to granular materials. A wide selection of processes and materials are available for the engineer. The course will describe the grouting methods and types of grouts used, suitability for the ground problems and degree of improvement attainable for different soils.
The primary uses for grouting ground formations are to: a) increase the strength and bearing capacity or the soil stability, b) reduce seepage and control groundwater during construction, c) form groundwater barriers and d) rehabilitate or reinforce structures. This course should be a guide for determining the types of grout and methods to use for improving a subgrade soil. The advantages and disadvantages of the commonly used grouts and additives are discussed along with various methods for application.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
