  • Patent number: 8459903
    Abstract: A connection device for fastening two expanded cellular confinement structures includes an insertion member having insertion ends, an insertion member extension, an integral shank, and a handle member. A cellular confinement system includes first and second webs of cells made from strips bonded together in spaced apart areas. The strips form walls of the cells and at least some of the cells define open slots. At least one connection device fastens the first web and the second web together through the open slots. A method of fastening two expanded cellular confinement structures includes aligning two expanded cellular confinement structures; inserting an insertion member of a connection device through open slots; and turning the connection device.

  • Publication number: 20100119766
    Abstract: A connection device for fastening two expanded cellular confinement structures includes an insertion member having first and second opposite insertion ends and an insertion member extension therebetween. An integral shank extends from the insertion member extension and is spaces from each of the first and second insertion ends. A handle member extends generally from the shank at an end of the shank that is remote from the insertion member. The handle member has first and second handle ends and a handle member extension therebetween. The shank is spaced from each of the first and second handle ends. A cellular confinement system includes first and second unitary webs of cells made from elongated plastic strips bonded together in spaced apart areas. The strips form walls of the cells and at least some of the cells define open slots. At least one open slot of a first unitary web of cells is aligned with at least one open slot of a second unitary web of cells to result in a cell overlap region.
