Claim 9:
10. A method of fastening two expanded cellular confinement structures together; the method comprising:
(a) aligning two expanded cell confinement structures so that at least one open slot defined by a first unitary web of cells is aligned with at least one open slot defined by a second unitary web of cells to form an overlap region having opposite first and second sides;
(b) inserting an insertion member of a connection device from the first side of the overlap region through the aligned open slots of the overlap region to provide:
(i) the insertion member on the second side of the overlap region;
(ii) a handle member of the connection device on the first side of the overlap region;
(iii) a shank between the insert member and the handle member extending through the overlap region; and
(iv) a washer section against the first side of the overlap region; the washer section being between the shank and the handle member; the washer section having an outermost radial portion extending radially outwardly of every portion of the handle member; the handle member having a wall extending from the first surface of the washer section without a gap between the wall and the first surface of the washer section; and

(c) rotating the handle member to rotate the connection device within the overlap region.
