Grouting Fundamentals & Current Practice 2019

The 4-day course (16.–19.9.2019, Munich) covers pressure grouting as a method to improve geotechnical properties of soils and rock masses, with special focus on mechanisms, theories, and practical applications of grouting to ground densification and strengthening, permeability reduction and groundwater cutoffs.

Major course topics include:

grout rheology
cementitious and chemical grouting procedures
overburden and rock drilling methods
optimizing grouting during construction
jet grouting
deep soil mixing
composite seepage barriers
compaction grouting
rock anchors and SBMA design
micropiles
compensation grouting
permeation grouting
GIN and RTGC in rock grouting
amenability theory
pre-excavation grouting for rock tunnels
concrete repair

The course also includes a half-day “hands-on” field demonstration focusing on grouting materials, procedures and equipment.

The curriculum has been developed specifically for Owners, Regulators, Consultants and Contractors having interest in the applications of pressure grouting to a broad array of geo-structural construction and remediation techniques.

Field Demonstration

A key component of the course is the 1/2-day practical field demonstration (Demo). Contractors, manufacturers and suppliers will converge on the UniBw campus to provide hands-on instruction concerning grouting equipment, materials and procedures. The 2019 Demo participants and their planned activities include:

ChemGrout: compact grout plant technology/colloidal mixers
