Curb ramps are usually made using waterproof and durable materials.Once they have been installed then you can pretty much leave them alone. For the best maintenance check your curb ramp every month or so to look for cracks or anything stuck into the material. If you find anything that could be detrimental to the curb ramp’s surface then it may need replacing. Curb ramps that have been bolted together will need an occasional once-over too, to check and see if the connections are still strong and not rusty. Rusty bolts will need replacing immediately. If your curb ramp has a reflective surface which has worn through, then you should replace these for new versions. If the treads have completely worn then you also should consider replacing the ramp, so you can maintain good traction.
