There's a lot of excitement in the Environmental Industry about Geoprobe® Prepacked Well Screens designed for setting Small Diameter Monitoring Wells. Prepacked screens consist of a standard, slotted PVC well screen pipe surrounded by a stainless steel mesh. 20/40 silica sand is packed between the slotted PVC and the stainless steel mesh. Since the sand is packed around the slotted PVC before the well screen is installed, using prepacks guarantees that sand will be located directly around the well screen. This makes well installation quicker, more efficient and does not generate cuttings associated with traditional auger methods. Direct Push monitoring well sizes include 0.5”, 0.75”, 1.0”, 1.5”, and 2.0” diameter wells.
If your needs include larger diameter wells, GeoTek also has the ability to install up to 4” diameter wells using Hollow Stem Auger (HSA).
