I have a proposal for 3 wells, each about 275' deep....based on WF GeoLoop software. Some drillers are proposing grouting the entire bore, others are proposing grouting only the top 60 or so feet, since the rest of the way down the pipe will be in water. We do have a high water table, that is roughly 30-40' from finish grade, even during moderate drouts. Will only grouting down 60', with rest of pipe in standing water in the well provide sufficient conductivity? Seems like it would, but I'm wondering why everything I read it seems that grouting 100% of well is the standard operating procedure. Any insights on this would be appreciated.
