Grouting The Casing
a properly grouted casing is very important. If the casing is not
grouted, it may be vulnerable to surface water containing harmful
bacteria like Ecoli and other contaminants such as Nitrates.
Manderson Well Drilling, we use a grouting method with borehole air
packers (see below). These packers expand under air pressure inside the
bottom of the casing. The bentonite slurry is then pumped through the
middle of the packer. Forcing the grout up, and around the outside of
the casing to the top of the ground. Filling any cavities in the rock or
till on the way. This creates a perfectly grouted casing seal.
