Isoflex™ is a closed-cell polyethylene foam isolation joint and expansion joint filler used in concrete construction.
The convenient, pre-perforated tear-off strip incorporated into the product makes it easy to create a void when using cold-applied sealants. Isoflex is particularly ideal for isolation joints accomodating different horizontal and vertical movement between the pavement and a structure.
