To fix the expansion joint, slots in the building use a rod backer rod to insert into the slot and then to fill. Backer Rod inserts are made of PE foam, with round cross section and multiple diameters to match all expansion joints. Backer rod slot inserts adjust the depth between the expansion joints and keep the retention of grout, minimizing the amount of glue to use when filling.
The backer rod insert must be compacted at the insertion site to ensure that it does not move during application, to ensure this requires a Backer Rod insert 25% larger than the insertion slot.
