Using Tremied Grout
Clear drilling mud and debris from borehole. Attach bottom cap to bottom section of casing.
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.
Lower steel bar or pipe to bottom of casing to counteract buoyancy while grout sets. Then lower grout
pipe to bottom of borehole and pump in grout.
Top off borehole with grout and install protective cover. Take initial readings, then hand over to client.
