—— COLUMN ISOLATION BLOCKOUTS · SLAB-ON-GRADE
THE CONCRETE
Pocket Form Isolator is a leave-in-place HDPE blockout for column isolation pockets. Set it on the footing, pour the slab, and it stays. Nothing to strip, nothing to wreck out, no chipped slab edges.

01 / THE PROBLEM
FOR NEARLY A CENTURY, COLUMN POCKETS WERE FORMED IN WOOD. THEN SOMEBODY HAD TO RIP THEM OUT.
THE OLD WAY
WOOD & FOAM BLOCKOUTS
✕
Built on site, then stripped or wrecked out after the pour
✕
Removal leaves unsupported or chipped slab edges
✕
Debris fills the pocket and fouls the column grout bed
✕
Needs fiberboard or a grout line to separate the pours
✕
Foam is often dissolved out with petrochemicals
THE PFI WAY
POCKET FORM ISOLATOR
✓
Ships on pallets with every part marked
✓
Stays in the slab for the life of the structure
✓
Clean, uniform edge, flush with finished floor elevation
✓
HDPE won't bond to concrete, so the form is the isolation joint
✓
Drill or cut it in the field for pipe, conduit and wiring
02 / WHY PFI
GREEN. CLEAN. CUSTOM.
GREEN
Engineered from high-density polyethylene that is over 50% recycled plastic. Recycled content can contribute to LEED credits.
CLEAN
HDPE resists bonding to concrete, so the joint stays clean and sealed. A fit for cold storage and sanitary food processing floors.
CUSTOM
Round and square forms in thousands of shapes and sizes, plus custom shapes for any plan with straight sides.
03 / SHAPES
PICK THE SHAPE. WE MATCH THE PLAN.
Every PFI is sized three ways: plan dimensions, shape, and depth, usually from the top of the footing to finished floor.
SQUARE &
RECTANGLE
Square and rectangular pockets: the SQ line.
ROUND
Round pockets, customized to the plan.
RACETRACK
Straight sides, rounded ends.
