Customers wanted a machine with similar features as the GP300 Injection Machine, but without the GP350’s weight ( 5 lb.). Weighing less than 150 lb., the GP350 can be loaded for transport by two people, and can be easily maneuvered around a project site by one field person. The machine was designed to inject remediation materials or for bottom-up grouting through small diameter probe holes. The GP350 is also capable of delivering standard ASTM grout mixes, and, based on the power source, provides operating pressures up to 1,300 psi with a maximum flow rate of 5 gpm. The machine is powered using auxiliary hydraulics on the Geoprobe® machine, so it’s adaptable for use in the field with multiple machines.
