To pump cement slurry into a well and place it in the annulus between the casing and the formation, or at the desired depth, at least 3 h is required for normal wells (≈ 10,000 ft), and for deep wells additional time is needed. Therefore the slurry should remain as low-viscosity fluid during that time and should harden rapidly when placed in …

Grouting with Neat Cement – Water Well Journal

Sealing casing: Note: In sealing casing, make sure that a "casing shoe shut-off" has been established between the bottom of the casing and the hole. This ensures that the sealing slurry remains in the annulus. Refer to typical mixing procedure steps 1-3. 1.) Pump the prepared BENSEAL® and EZ-MUD® slurry through a 1.0–1.25 inch (25-32

The progressive cavity Rotor – Stator type pump is a perfect solution when pumping viscous, abrasive or solid laden materials, to pump neat cement, bentonite, cement / bentonites, ultra fine cements and some smooth, creamy, lightly sanded packaged grout mixes, cement / sand mortar and plaster coats.

Drill rods or casing may be washed into place and used to inject the compaction grout. This method is effective where the limestone lies deep beneath the surface or when soil conditions cause the drill hole to collapse or cave prior to installing the steel casing. ^Back to Top.
