Pulled out my rotted 1x4 expansion wood and will have 1-2" void under backer rod when installed. Any requirement to put something like sand under it?
Can this rod be easily compressed to fit into narrow spaces?
Can this be used as concrete joint filler?
it is stiff enough to force into the void in the garage door bottom seal? I just replaced the seal and was looking for something to help keep shape
