ECT's Expanding Bentonite Sleeve & Foam Bridge thread above the Prepacked Well Screen to provide a fast, low permeability annular seal below the water table. Bentonite Quick Sleeves and Foam Bridges are available individually or as a combo unit. Bentonite sleeves and foam bridges can be stacked in line for a superior level of protection. 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).
