Edging for playground pad. Many competitors and installers will use a preessure treated nailer board to hold playground pads in place. We have found the use of flexible edging to be easier to work with, faster to install and the curves that can be created are not possible with 2 by 4 nailer boards. These products will never rot and are recyclable. See the images for how we install the edging and how the final installation can look. Simply backfill up to the edge with landscape material or soil and sod for a seamless transition.
