Jet Grouting Systems: Advantages and Disadvantages
The process of jet grouting has become a worldwide system of ground treatment. Specialized equipment vendors abound, each focusing on a niche of the jet grouting market. Specialty contractors build their experience using certain equipment and procedures so that they may be better apt to understand the risks that they assume. This paper will compare the jet grouting systems available today, and bracket the parameters most often utilized. The author discusses three primary systems of jet grouting: the single fluid system, which entails the injection of cementitious grout slurry at high velocity to erode and mix with the soil; the double fluid system, which features the injection of cementitious grout slurry at high velocity, sheathed in a cone of air at an equally high velocity, to erode and mix with the soil; and the triple fluid system, which is the injection of water at high velocity, sheathed in a cone of air at an equally high velocity, to erode the soil while simultaneously tremie injecting a cementitious grout slurry from beneath the erosion jets. A discussion on the advantages and disadvantages of each system will be presented as well as how they may influence performance for a variety of applications. This evaluation should offer a guide for a better understanding of this often misunderstood technology. The author concludes that, of all the ground treatment systems, jet grouting is the most complex, requiring experience in order to predict product quality, as well as to determine the method to achieve it. Soil type and stratigraphy evaluation are critical to this determination. The author recommends that specifications developed for this work should be performance-based, with a method of considering experience as well as cost in the selection process.
