Looking for economical suggestions for concrete expansion joint filler.
I have a double wide driveway that is about 30' long so I have many joints that need to be filled.
I plan on back filling with foam backer rod but I need to find a good product to seal the joint.
I live in Minnesota so it needs to withstand the extreme cold and our extreme heat cycles.
I would be looking for something to match the concrete grey color.
Please respond with suggestions/tips, etc.
