Drilling a Commercial Well

Drilling a Commercial Well requires special grouting requirements, water testing, and engineered plans…it really isn’t that much different than a residential well.  We centralize our casing to get a more uniform grout.  We widen the hole to achieve a 2″ annulus between the earth and casing…this ensures a complete and unpenitrable grout.  We grout to 100′ on most commercial wells in the Lowcountry….
The pictures below are from a Dollar General store that needed a well for public supply.
This is what the casing is set into.  Locally known as Marl, it has properties similar to clay.
  

This is a picture of the centralizers for the casing…we custom made those.

This is our drill rig cutting the casing hole…

This is the mess it makes!
