  • Protective covering for landscape ties and timbers and other building materials
    Patent number: 7503990
    Abstract: Apparatus and methods for preventing splinters and minimizing the number of injuries attributable to falling onto pressure-treated wooden members, such as landscape ties or timbers used in play areas and landscape projects, through the use of a resilient cover. A cover and various embodiments include a moldable or extrudable waterproof material in the form of a channel having a top wall and two opposing side walls. The combination of channel thickness and composition provides an impact resistance suitable to prevent injuries when one falls upon it. The inner dimensions of the channel are such that the channel fits tightly over the top and sides of a construction beam or timber.
