Conform Fibre Expansion Control Joint Filler from CAgroup uses a proprietary process that thoroughly mixes wood fibres in an asphaltic binder, then forms the fibres into a rigid board.

The result is an economical, environmentally safe compressible material that’s stronger yet easier to handle than other joint filler compounds.


Conform is ideal for use as a filler strip in expansion control joints for most types of concrete construction.

  • Meets or exceeds AASHTO and ASTM specifications – Approved by several state Departments of Transportation.
  • Cuts cleanly, and it is easily held in position during concrete pouring.
  • Will not extrude from joint under compression – recovers substantially to original thickness after release from compression.
  • Resists water infiltration.
  • Withstands freeze / thaw cycles.


Conform Fibre Expansion Joint Filler is suitable for use with expansion joints in a wide variety of concrete construction projects. Also ideal for medium to large concrete slab work and other flatwork applications.
