An Introduction to Chemicals for Grouting of Soils

COURSE NO: G03-006
An Introduction to Chemicals for Grouting of Soils
Course Highlights

This online engineering PDH course provides information and guidance for the investigation and selection of materials, equipment and methods to be used in chemical grouting in connection with construction projects. Elements discussed include types of chemical grout materials, grouting equipment and methods, planning of chemical grouting operations, and specifications. Emphasis is placed on the unique characteristics of chemical grouts that benefit hydraulic structures.


Chemical grouts were developed in response to a need to develop strength and control water flow in geologic units where the pore sizes in the rock or soil units were too small to allow the introduction of conventional portland-cement suspensions. The first grouts used were two-stage grouts that depended on the reaction between solutions of metal salts and sodium silicate. The technology has expanded with the addition of organic polymer solutions and additives that can control the strength and setting characteristics of the injected liquid.


Chemical grouting has become a major activity in remediation and repair work under and around damaged or deteriorated structures. Much of the technology for large-scale grouting of rock or soil can and has been adapted into equipment for repairing concrete structures such as pond liners, drains, or sewers. In the selection of a grout for a particular application, certain chemical and mechanical properties, such as viscosity, durability and strength should be evaluated.


This 3 PDH online course is intended for civil and geotechnical engineers and other design and construction professionals seeking an introduction to the use of chemical grouts to improve the structural properties of soil.
