Using Grout Valve
1
Clear drilling mud and debris from borehole. Attach grout valve to bottom section of casing.
2
Install casing in borehole, adding casing sections as necessary until casing reaches specified depth. In
water-filled boreholes, fill casing with water to counter buoyancy. In dry boreholes, install dry casing.
Fill casing with water to counter buoyancy when grouting begins. Keep water at same level as grout to
avoid disturbing sealed couplings.
3
Lower grout pipe into casing to connect with grout valve. Start pumping grout. Water level in borehole
should rise if grout pipe is properly connected to grout valve.
4
Halt pump when grout appears at top of borehole. Hold casing down and disconnect grout pipe. Flush
casing with clean water. With quick-connect grout valves, retrieve grout pipe, then flush casing. Lower
steel bar or drill pipe to bottom of casing to counter buoyancy while grout sets. Top off borehole with
grout and install protective cover. Later, take initial readings, then hand over to client.
