Abstract: A connection device for fastening two expanded cellular confinement structures includes: an insertion member; an integral shank extending perpendicular from the insertion member; and an integral handle member extending perpendicular from the shank at an end of the shank remote from the insertion member. One or more barbs may project from the insertion member. The device can have a washer section between the handle member and insertion member. The handle can be curved, or it can be in the shape of a polygon.

Abstract: A vented cell structure for confinement and interlock of earth materials comprising polymeric strips bonded together on their faces in a side by side relationship at bonding areas which are staggered from strip to strip such that the plurality of strips may be stretched in a direction perpendicular to the face of the strips to form a layer of cells. The strips form walls of the cells, and each of the cells has an open interior. At least some of the strips having openings through the strips providing communication with the open interior of the cells. The strips have improved coefficients of friction and interaction over the prior art. In some examples, at least one of the openings has an open area of greater than 804 mm2.
