Project Description

Drill Rig Grout Inlets

Grout inlets allow pressurized grout to be injected into the center of the drill string allowing grout or cement to flow through Holte’s patented hammer and bit.  Air and Hydraulic Valves can be installed above grout inlets to prevent grout from traveling through the system incorrectly.
