Purpose and Background

Jet grouting is defined as the injection of a fluid grout at high pressure to erode the soil partially replacing it and creating a soil-crete. This method is often used to for structural support, creating low permeability barriers, shoring, and underpinning. Applications are many, including liquefaction mitigation, controlling structure settlement, roof support for tunnels, mitigating karst subsidence, slope reinforcement, structural support, and more.

This webinar includes an introduction to jet grouting and the critical factors associated with its application. It includes an overview of materials and equipment for grout injections and considerations for applying the method. This webinar discusses behavior of the grout in the subsurface and provides understanding of the various factors affecting the control, verification, and effectiveness of jet grouting. It presents examples of some of the key applications.

How to Earn your CEUs/PDHs and Receive Your Certificate of Completion

To receive your certificate of completion, you will need to complete a short on-line post-test and receive a passing score of 70% or higher within 1 year of purchasing the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
