  • Patent number: 8266844
    Abstract: A paver or landscape edging is provided with enhanced anchoring means. The edging has an elongated, longitudinal strip with a paver-facing surface and an opposed surface, and extensions extending from the opposed surface of the elongated strip, each comprising a first wall edge and a bore for receiving a fastener such as a spike or stake. A strap member extends between neighboring extensions, offset from the first wall edge and defining a gap, or anchoring region, when the edging is placed on a substrate. The installed edging may be anchored by fasteners, and by root systems of a concealing layer placed over the edging that grow around the strap member. In addition, a method for installing pavers provides for the fixing of a portion of the edging on the substrate prior to cutting a strap to allow the edging to be deformed in conformance with a curved or irregular boundary.
