For almost a century, column isolation pockets have been built using temporary wooden forms. Today, PFI offers a customized, environmentally friendly alternative that provides a clean, uniform finish every time. 

Pocket Form Isolator is a "leave-in-the-slab" isolation pocket engineered of high density polyethylene (HDPE) -a material that does not bond to concrete- creating the perfect isolation between inner and outer pours.

We offer thousands of shapes and sizes customized for virtually any shape or dimension you need.
