Pocket Form Isolator is a ‘leave-in-the-slab’ isolation pocket, or diamond block-out engineered of high-density polyethylene (HDPE). Wood, Styrofoam, and other materials currently used to create block-outs all have a common flaw – they must be ‘wrecked-out’ after the slab in place! Using PFI does away with wrecking-out diamonds, eliminates unsupported and or chipped slab edges, as well as debris-filled pockets that could prevent the proper placement of the column base grout bed. Because HDPE does not bond to concrete and because PFI sits at finished floor elevation, it becomes the optimum separation and expansion joint between the inner and outer concrete pours, eliminating the need for grout lines, fiberboard, or other separation methods in use today.
PFI has been successfully used in the slabs of Super Target, Target, Wal-Mart, Super Wal-Marts, Sam’s Clubs, Home Depot Stores, public schools, supermarkets, the new Georgia International Convention Center and a variety of other commercial and industrial structures.
