CURBING IS IMPORTANT FOR A NUMBER OF REASONS. IT DEFINES THE EDGE OF THE PARKING LOT AND PREVENTS CARS FROM DRIVING OVER THE SIDE, PROTECTS LANDSCAPE AND IT RETAINS LANDSCAPING MATERIALS DURING INCLEMENT WEATHER. TO KEEP WATER FROM RUNNING OFF, WE RECOMMEND YOU PUT IN A CURB TO HELP CATCH WATER AND OTHER MATERIALS TO PREVENT BUILD UP.
