This product was intended to allow for one ethernet cable and one water hose to be laid across the driveway without being damaged. It works to my satisfaction. We have one car and one pickup truck, and the items have not been damaged at all over several months of using thus product. FYI: The area where these are placed is ten feet wide, so three were required. Interlocking them was no problem at all. Also... it is best if they are bolted to any driveway, because it is highly likely vehicles can cause them to move.
