Asphalt Crack Backer Rod

Asphalt Crack Backer Rod is designed for the purpose of "Pre-Filling" cracks in asphalt that are deeper than 1/2" in depth.

This Foam Backer expands and seals the crack prior to the Crack Sealing process so that the new rubber material won't bottom out in the crack, this also saves you a great deal of material.

Some Asphalt Crack Filling professionals use fine sand for this purpose. Using sand works well in most applications and is usually easy to come by. On the down side, the problem you may encounter using sand is that when the crack expands (and it will) due to heat or cold temperature changes, the sand has a tendency to fall deeper into the crack or as the crack widens the sand will not support new sealer.

Asphalt Crack Backer Rod is installed so it "Pushes" against the side of the crack and as the crack widens, the Backer Rod widens with it because it is constructed from foam rubber.

Asphalt crack backer rod is very easy to install and as the pictures to the right show, simply push the Rod material down into the asphalt crack so you have approximately 1/2" of depth from the rod to the asphalt surface. Next, pour your new Asphalt Crack Filler on top.
