Prepacked water wells ensure a positive screen placement that blocks unwanted water from entering the well. Prepacked Screen Monitoring Wells are designed to be installed through most direct push casings or can be installed in an open hole. Each section is flush threaded with an O-ring seal for assembly to additional Pre-Pak Screens, Foam Bridges, Bentonite Sleeves (Quick-Seals) or flush threaded casings. The use of the Prepacked Well Screens, Combination Bentonite Quick Seal Sleeves and Expanding Foam Bridges can make well installations go smoother by taking the guesswork out of gravel pack and annular seal placement, which can be a problem when working with heaving sands or with limited annular space such as with Direct Push Installations. 2" Slim Prepacks are in stock. Custom projects are our specialty.
