Annular Bentonite Seals

ECT's Expanding Bentonite Sleeve & Foam Bridge Combo threads above the Prepacked Well Screen to provide fast, low permeability annular seal below the water table. Use of Prepacked Well Screens, Combination Bentonite Quick Seal Sleeves and Expanding Foam Bridges take the guesswork out of gravel pack and annular seal placement (a common problem when working with heaving sands or limited annular space such as Direct Push Installations).
