A method of preventing injury by retrofitting a play area or landscape project defined by at least one rectangular pressure-treated wooden member, comprising the steps of: fitting a channel comprised of a resilient material having a top wall, two opposing side walls, a lip located at the bottom of at least one of the opposing side walls providing a flange substantially perpendicular to the at least one of the two opposing side walls, and a thickness sufficient to provide impact resistance, snugly over at three sides of at least one rectangular pressure-treated wooden member defining a play area or landscape project; forming a trench within the ground adjacent and at substantially the depth in the ground as the at least one rectangular pressure treated member; inserting a lower edge of at least one of the opposing side walls into the trench below the ground upon which the at least one rectangular pressure treated member rests; covering the lip located at the bottom of at least one of the opposing side walls with at least dirt in order to secure the position of the at least one rectangular pressure treated member; and fastening the channel to the at least one rectangular pressure-treated rectangular wooden member.
