Grouting The Casing


Having 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.


At 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.
