Tenant damaged concrete

Two years ago I had a rental built that has a 20 foot curved concrete walk way. We have had the same tenants for two years and they just moved out. While moving out they drug a safe all the way down the walk way leaving gouges down all 20 feet of the walk way. I called a local concrete guy an he said it would be easier to repour the entire thing then try and fix it. How do I deduct from the deposit for this type of damage? I don’t think it is economical to fix.
