Pre-Pak Screens are installed in small diameter open boreholes or through direct push drive rod, at the bottom of the riser pipe to create a filter packed well in one step without adding sand around the screen separately. Pre-Paked screen sections have flush threads so they screw on to compatible riser to save time and aid in producing a less turbid monitoring well.
The filter pack material is clean, silica sand contained evenly around the outside of PVC slotted well screen with a mesh or filter sock. The diameter is controlled so that a uniform filter thickness is achieved so the screen fits in the space available. A variety of filter sand gradations is available to best match natural formation conditions.
