Abstract:
Whether you call them spoils, backflow, returns or waste, the by-product of jet grouting is a very important part of the process. This paper explains why this is true and what effects can be seen when the proper fluid returns are impeded. It shall cover spoils basics, the insights into the jet grouting process they provide, and quantities that should be anticipated. This paper will also explore options for conveying and managing spoils on a work site with the use of various pumping equipment or through gravity flow techniques. Spoils reduction with the use of processing plants is also covered.
